Abstract
Since diarrhoea is reportedly the third largest cause of fatality among kids, therefore it is considered to be one of the major areas of concerns among developing nations. The main causative agents of diarrhoea include Escherichia coli, Vibrio cholera, and Shigella spp where E. coli shares the maximum contribution. The roots of the plant Eriosema chinense Vogel. (Fabaceae) are traditionally used by the native tribes of Meghalaya, India to treat diarrhoea. From previous reports, the plant and its marker eriosematin E have been reported to have antidiarrhoeal potential against pathogenic and nonpathogenic diarrhoea. Therefore, the objective of the current investigation was to use in silico studies to determine the efficacy of eriosematin E against different diarrhoeagenic strains of E. coli. Six different pathovars of E. coli i.e. enteropathogenic E. coli (EPEC), enterotoxigenic E. coli (ETEC), enterohaemorrhagic E. coli (EHEC), enteroaggregative E. coli (EAEC), uropathogenic E. coli (UPEC) and enteroinvasive E. coli (EIEC) were subjected to docking simulation studies utilizing Glide module of Schrodinger Maestro 2018-1 MM Share Version. Based on the obtained binding energy and balance between H-bonding, hydrophobic, and salt bridge interactions eriosematin E was found to be most effective against EPEC followed by EAEC and ETEC, while UPEC and EHEC were moderately affected. The molecular dynamics studies suggested a higher affinity of eriosematin E towards heat-labile enterotoxin b-pentamer from ETEC. The in vitro antibacterial studies against the universal strain S. aureus 12981 and E. coli 10418 revealed the effectiveness of eriosematin E showing MIC values of ≥256 µg/mL.Communicated by Ramaswamy H. Sarma.

COVID-19-Associated Sepsis: Potential Role of Phytochemicals as Functional Foods and Nutraceuticals. Int J Mol Sci 2024; 25:8481. [PMID: 39126050 PMCID: PMC11312872 DOI: 10.3390/ijms25158481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2024] [Revised: 07/30/2024] [Accepted: 08/01/2024] [Indexed: 08/12/2024] Open
Abstract
The acute manifestations of coronavirus disease 2019 (COVID-19) exhibit the hallmarks of sepsis-associated complications that reflect multiple organ failure. The inflammatory cytokine storm accompanied by an imbalance in the pro-inflammatory and anti-inflammatory host response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection leads to severe and critical septic shock. The sepsis signature in severely afflicted COVID-19 patients includes cellular reprogramming and organ dysfunction that leads to high mortality rates, emphasizing the importance of improved clinical care and advanced therapeutic interventions for sepsis associated with COVID-19. Phytochemicals of functional foods and nutraceutical importance have an incredible impact on the healthcare system, which includes the prevention and/or treatment of chronic diseases. Hence, in the present review, we aim to explore the pathogenesis of sepsis associated with COVID-19 that disrupts the physiological homeostasis of the body, resulting in severe organ damage. Furthermore, we have summarized the diverse pharmacological properties of some potent phytochemicals, which can be used as functional foods as well as nutraceuticals against sepsis-associated complications of SARS-CoV-2 infection. The phytochemicals explored in this article include quercetin, curcumin, luteolin, apigenin, resveratrol, and naringenin, which are the major phytoconstituents of our daily food intake. We have compiled the findings from various studies, including clinical trials in humans, to explore more into the therapeutic potential of each phytochemical against sepsis and COVID-19, which highlights their possible importance in sepsis-associated COVID-19 pathogenesis. We conclude that our review will open a new research avenue for exploring phytochemical-derived therapeutic agents for preventing or treating the life-threatening complications of sepsis associated with COVID-19.

Evaluation of In Vivo Antidiarrheal Activities of 80% Methanol Extract and Solvent Fractions of Peels of Colocasia esculenta (Araceae). EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2024; 2024:2728282. [PMID: 39035348 PMCID: PMC11259501 DOI: 10.1155/2024/2728282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 04/20/2024] [Accepted: 04/24/2024] [Indexed: 07/23/2024]
Abstract
Background Diarrhea is the common gastrointestinal disorder accounting for 2.5 billion episodes and 1.5 million deaths annually. Limitations and inaccessibility of currently available medications are the main problem associated with treatment of diarrhea. Hence, medicinal plants are usually preferred to manage diarrhea because they may contain constituents with high activity and fewer side effects. Even though the dose, safety, and efficacy of Colocasia esculenta (L.) Schott are not substantiated scientifically, several societies use it for the treatment of diarrhea. Objective This study was targeted at exploring the in vivo antidiarrheal activities of 80% methanol extract and solvent fractions of peels of Colocasia esculenta (L.) Schott in Swiss albino mice. Methods The plant was collected and extracted with 80% methanol, followed by fractionation with distilled water, chloroform, and diethyl ether. Castor oil-induced diarrhea, enteropooling, and motility tests were used to evaluate antidiarrheal activity. The test groups received graded doses of 100 mg/kg, 200 mg/kg, and 400 mg/kg. Negative controls received 10 ml/kg of 2% Tween 80 while positive controls received loperamide (3 mg/kg) or atropine (5 mg/kg). Results The crude and solvent fractions of the plant extract have induced significant effects in reduction of the number and weight of wet stools at all tested doses. However, delay in onset of diarrhea was observed only at 400 mg/kg (P < 0.001) for both crude extract and solvent fractions. In antienteropooling test, 80% methanol extract and solvent fractions have significantly reduced the weight and volume of intestinal contents, especially at 200 mg/kg and 400 mg/kg. Regarding the antimotility test, the crude extract reduced motility at all tested doses, whereas the solvent fractions reduced intestinal motility mainly at 400 mg/kg (P < 0.001). Conclusion The study has revealed that the 80% methanol extract and solvent fractions of the plant possess antidiarrheal activities supporting the traditional antidiarrheal claims of the plant.

Abstract
Background People frequently complain of long-term constipation. The cost associated with using modern medications to treat constipation is significant, and the probability of encountering side effects is notably high. These limitations restrict their effectiveness in therapy, remain unresolved, and underscore the need for research on alternative therapeutic approaches. Plants of the genus Artemisia have been used to treat constipation. Therefore, the aim of this study was to evaluate the laxative effects of aqueous A. abyssinica leaf and stem extracts of Artemisia abyssinica in mice. Methods The laxative activity of A. abyssinica leaf and stem extracts was evaluated using three models: laxative activity, gastrointestinal motility, and gastrointestinal secretion. In this study, bisacodyl was used as a standard laxative and loperamide was used to induce constipation. Results In the laxative test, 200 (P<0.05) and 400 mg/kg (p<0.01) doses of plant extract significantly increased the percentage of fecal water content. Moreover, the highest dose of extract increased the frequency of defecation after 12 h (p<0.05). In the remaining two models, the experimental plans also showed significantly higher gastrointestinal motility and noticeable accumulation of intestinal fluid. Conclusion The results of this study indicate that aqueous leaf and stem extracts of A. abyssinica have laxative effects.

Abstract
Background Liver disease is any disease that negatively affects the normal function of the liver, and it is a major health problem that challenges not only healthcare professionals, but also the pharmaceutical industry and drug regulatory agencies. Similarly, diarrhea is the second leading cause of death among children under five globally next to pneumonia. The available synthetic drugs for the treatment of liver disorders and diarrhoea have limited safety and efficacy. Objective To evaluate the in vivo hepatoprotective and antidiarrheal activities of hydroalcoholic leaf and fruit extracts of Schinus molle L. (Anacardiaceae) in mice. Methods Hepatoprotective activity of the extracts was evaluated by using CCl4 induced hepatotoxicity in mice model. In this model, mice were divided into groups and treated as follows. The normal control and toxicant control groups were treated with the vehicle used for reconstitution, the positive control was treated with the standard drug (silymarin), and the test groups were treated with different doses of plant extracts daily in the morning for seven days. Additionally, all groups except the normal control were treated with CCl4 (2 mg/kg, IP) on the 4th day of treatment, 30 min post-dose. On the 7th day, blood was collected from each mouse via a cardiac puncture. The collected blood was centrifuged, and serum levels of ALT, AST, and ALP were determined using an automated chemistry analyser. Data were analysed using one-way analysis of variance (ANOVA) followed by Tukey's post-hoc test.The antidiarrheal activity of the extract was investigated using castor oil-induced diarrhoea, enteropooling, and small intestine transit. The test groups received various doses (100, 200, and 400 mg/kg) of the extract, whereas the positive control received loperamide (3 mg/kg), and the negative control received the vehicle (distilled water, 10 ml/kg). Result Hepatoprotective activity: The leaf and fruit crude extracts showed significant improvement in the body weight and liver weight of mice compared to the untreated toxicant control. Additionally, treatment with hydromethanol leaf and fruit extracts caused a significant (P < 0.05) improvement in liver biomarkers compared to the toxicant control. Similarly, the n-butanol and chloroform fractions of the fruit extract caused a significant reduction (P < 0.01) in serum AST, ALT, ALP and Bilirubin levels and a significant (P < 0.001) increase in total protein compared to the toxicant control. However, none of the three solvent fractions (n-butanol, chloroform, and aqueous) of the fruit extract significantly affected (P > 0.05) the level of albumin compared with the toxicant control.Antidiarrheal activity: In the castor oil-induced diarrheal model, the 80 % methanol extract delayed the onset of defaecation and significantly reduced the number and weight of faeces at all tested doses compared to the negative control. In the enteropooling test, 80 ME significantly (P < 0.001) reduced the weight and volume of intestinal fluid at all tested doses compared with the negative control. Results from the charcoal meal test revealed that the extracts produced a significant anti-motility effect at all tested doses compared with the negative control. Conclusion This study confirmed the hepatoprotective and antidiarrheal activities of hydroalcoholic extracts. The highest test dose produced the maximum hepatoprotective and antidiarrheal activities in all models.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE A comprehensive checklist and analysis of medicinal plant species and their uses in Mozambique, and a comparison with South Africa provided a more profound understanding of the broad concept of Traditional African Medicine as a healing culture and the need for a more informative classification system. AIMS OF THE STUDY This study was aimed at recording all medicinal plants reported in Mozambique according to literature and answer four main questions. 1. How many medicinal plant species have been recorded for Mozambique? Of those, how many are indigenous to Mozambique, and how many are introduced or cultivated exotics? 2. What are the main medicinal uses in Mozambique and which species are used for which ailments? 3. What are the similarities and differences between the medicinal floras of Mozambique and South Africa - are the same species used for the same ailments and is there evidence of cultural exchange? 4. Do the data provide new insights into Traditional African Medicine as one of the oldest medicine systems in the world? MATERIALS AND METHODS A literature survey was done to compile the medicinal checklist of Mozambique using 29 available literature sources, which were found from published books, journal articles, reports, unpublished theses, dissertations, and online databases. RESULTS A total of 731 medicinal plant species and infraspecific taxa from 447 genera and 120 families was recorded for Mozambique. Of these, 590 (81%) are indigenous, and 87 are non-indigenous (50 naturalised and 37 cultivated exotics). Of the 731 medicinal plant species, 494 (68%) are also used medicinally in South Africa and 148 (30%) are used for the same or similar ailments. Many of the shared taxa and uses have been recorded in the adjoining KwaZulu-Natal Province of South Africa, which has similar vegetation types. CONCLUSION The similarity between Mozambique and South Africa (and especially the KwaZulu-Natal Province) not only suggest an exchange of traditional knowledge but also indicates the existence of a hitherto unnamed medicinal system of the southern and eastern African Bantu-speaking cultures that is in need of detailed comparative studies.

A scoping review on efficacy and safety of medicinal plants used for the treatment of diarrhea in sub-Saharan Africa. Trop Med Health 2024; 52:6. [PMID: 38173018 PMCID: PMC10763068 DOI: 10.1186/s41182-023-00569-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Accepted: 12/18/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND In sub-Saharan Africa (SSA), significant morbidity and mortality have been linked to diarrhea, which is frequently caused by microorganisms. A rise in antimicrobial-resistant pathogens has reignited the search for alternative therapies. This scoping review aims to map the literature on medicinal plants in relation to their anti-diarrheal potential from SSA. METHODS Studies published from 1990 until April 2022 on medicinal plants used for the treatment of diarrhea from each country in SSA were searched on Scopus, Web of Science, Science Direct and PubMed. The selection of articles was based on the availability of data on the in vitro and/or in vivo, ethnobotanical, and cross-sectional studies on the efficacy of medicinal plants against diarrhea. A total of 67 articles (ethnobotanical (n = 40); in vitro (n = 11), in vivo (n = 7), cross-sectional (n = 3), in vitro and in vivo (n = 2) and ethnobotanical and in vitro (n = 2), were considered for the descriptive analysis, which addressed study characteristics, herbal intervention information, phytochemistry, outcome measures, and toxicity findings. RESULTS A total of 587 different plant species (from 123 families) used for diarrhea treatment were identified. Most studies were conducted on plants from the Fabaceae family. The plants with the strongest antimicrobial activity were Indigofera daleoides and Punica granatum. Chromatographic methods were used to isolate six pure compounds from ethyl acetate extract of Hydnora johannis, and spectroscopic methods were used to determine their structures. The majority of anti-diarrheal plants were from South Africa (23.9%), Ethiopia (16.4%), and Uganda (9%). This study highlights the value of traditional remedies in treating common human diseases such as diarrhea in SSA. CONCLUSION Baseline knowledge gaps were identified in various parts of SSA. It is therefore recommended that future ethnobotanical studies document the knowledge held by other countries in SSA that have so far received less attention. Additionally, we recommend that future studies conduct phytochemical investigations, particularly on the widely used medicinal plants for the treatment of diarrheal illnesses, which can serve as a foundation for future research into the development of contemporary drugs.

Abstract
Restrictions on the use of antimicrobial compounds have led to a surge of interest in alternative solutions, such as natural, plant-based compounds. In our study, we investigated the efficacy of three feed supplements containing different additives, namely, probiotics (Lactobacillus spp., "Test substance A"), turmeric (Curcuma longa L., "Test substance B"), and fenugreek (Trigonella foenum graecum, "Test substance C"). In the experiment, we tested 180 birds of the Bábolna Tetra-SL laying hybrid breed that were infected with Salmonella enteritidis strains. The birds were randomly divided into six groups: three groups treated with the different additives, a negative control group, a positive control group, and an antibiotic-treated group using enrofloxacin. We examined the maturation and the time course of shedding of Salmonella; at the end of rearing, pathological and histopathological examinations were performed. When Salmonella was isolated from the cloacal swab samples, the enrofloxacin-treated group had a high number of animals shedding Salmonella by day 9, which was like the group treated with test material C. The greatest reduction in Salmonella shedding was observed in the groups treated with test materials A and B. In terms of pathological parameters, villus length and crypt depth were significantly better in the group treated with test material C compared to the positive and negative controls, and when comparing the body weight of the tested animals, the group treated with test material B had a significantly larger absorption surface area compared to the positive control group. Overall, the supplement with test material C proved to be the most effective. In the future, it is worthwhile to investigate the combination of the tested active substances for their possible synergistic effects and to perform a dose-response study to select the optimal dosage.

Abstract
Background Olinia rochetiana has been used traditionally to cure diarrheal disease. Therefore, this study aimed to investigate the acute toxicity and antidiarrheal effect of O. rochetiana leaf extracts. Methods Cold maceration was used to extract plant leaf powder with 80% methanol. The extract's antidiarrheal action was tested against a castor oil-induced diarrheal model, a charcoal meal test, and enteropooling tests at doses of 100, 200, and 400 mg/kg. Negative controls received the vehicle at 10 mL/kg, while positive controls received loperamide at 3 mg/kg. Results From the study, no apparent toxicity was observed when a single dose of 2000 mg/kg was administered. In the castor oil-induced model, the extract delayed the onset of diarrhea, reduced stool frequency, and decreased wet feces weight and number in a dose-dependent manner at 200 mg/kg (p < 0.05) and 400 mg/kg (p < 0.01). The percent reduction in moist feces at 100, 200, and 400 mg/kg was 54.2, 23.97, and 18.26%, respectively, indicating a significant dose-dependent decrease. In a charcoal meal test, the extracts at 200 and 400 mg/kg revealed a peristaltic index of 65 and 46%, respectively, with considerable inhibition of charcoal transport at 23 and 39%. The weight and volume of intestinal contents dropped significantly at a dose of 400 mg/kg (p < 0.01), which is 0.43 mg/kg, in the enteropooling test when compared with the tested dose. The computed in vivo antidiarrheal index revealed diarrheal inhibition values of 46.06 and 71.06% at 200 and 400 mg/kg, respectively. Conclusion In the current investigation, O. rochetiana showed significant antidiarrheal activity with no symptoms of toxicity in mice.

Integrated traditional herbal medicine in the treatment of gastrointestinal disorder: the pattern of use and the knowledge of safety among the Eastern Region Saudi population. BMC Complement Med Ther 2023; 23:373. [PMID: 37872543 PMCID: PMC10591345 DOI: 10.1186/s12906-023-04197-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Accepted: 10/04/2023] [Indexed: 10/25/2023] Open
Abstract
BACKGROUND Herbal medicine is commonly integrated with conventional medicine in Saudi Arabia, especially for the management of digestive disorders. However, the majority of Saudis use herbal remedies without prior consultation with a physician, which raises concerns about their appropriate and safe use. The aim of this study was to assess the level of awareness among the Saudi population regarding the proper utilization and potential adverse effects of frequently used herbs for the treatment of gastrointestinal (GI) diseases. METHODS A cross-sectional survey was conducted in Saudi Arabia from January to March 2021. An electronic self-administered questionnaire was distributed. RESULTS A total of 543 participants from different age groups, educational levels, and cities across Saudi Arabia completed the study questionnaire. The most commonly used herbs at home by the participants were: myrrh, parsley, black seed, chamomile, mint, anise, clove, and green tea. 57.7% of the participants perceived herbs as safer than conventional medicines; 27.3% reported that using herbal remedies over conventional medicine was a family tradition, and 21.4% used herbs because they were cheaper than conventional medicines. CONCLUSION Herbal remedies, including myrrh, parsley, blackseed, chamomile, mint, and anise, are commonly employed for the treatment of gastrointestinal disorders in Saudi Arabia. However, the knowledge level of participants regarding potential side effects and drug-herb interactions was found to be deficient. As such, there is a pressing need for educational campaigns and community awareness programs to elucidate the proper usage of herbal remedies and to caution against their potential adverse effects.

C.B.Rob.) leaf extract in chemical-induced models of albino rats. JOURNAL OF ETHNOPHARMACOLOGY 2023; 308:116189. [PMID: 36791925 DOI: 10.1016/j.jep.2023.116189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 01/15/2023] [Accepted: 01/17/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Diarrhea is one of the leading causes of preventable death in developing countries, mainly caused by bacterial infections and traditional therapies are very common in diarrheal incidences. Meda Pata (Litsea glutionsa) has a long history of use as traditional medicine for diarrhea, dysentery, and spasm in Bangladesh, India, and some other Asian countries. AIM OF THE STUDY This research reports the antidiarrheal effects of Meda Pata (Litsea glutinosa leaf extract, LGLEx) in animal models. The work has been supported by in silico molecular docking study to verify the effects. MATERIALS AND METHODS The antidiarrheal effect of LGLEx was investigated in castor oil-induced diarrhea, magnesium sulfate-induced diarrhea, and gastrointestinal motility test models. Antidiarrheal effects were supported by a molecular docking study through an interaction between LGLEx's GC-MS analyzed imidazole-containing compounds and muscarinic acetylcholine receptor (PDB: 4U14) and 5-HT3 receptor (PDB: 5AIN). RESULTS LGLEx potentially reduced the diarrheal incidences in in vivo assays reducing gastrointestinal motility. The maximum diarrheal inhibition was obtained in the castor oil-induced model (62.63%) and and BaSO4-induced model (73.14%), which were statistically significant (P < 0.05) when compared to the reference drug loperamide. In the castor-oil and BaSO4-induced models, peristaltic movement was reduced by 25.96% and 32.17%, respectively. Biochemical markers particularly IgE, C-reactive proteins, and serum electrolytes were significantly (P < 0.0) restored in treated groups. A Molecular docking analysis revealed that two compounds (1-Ethyl-2-hydroxymethylimidazole and 1,6-Anhydro-beta-D-glucofuranose demonstrated the highest binding affinity with target receptors muscarinic acetylcholine receptor (PDB: 4U14) and 5-HT3 receptor (PDB: 5AIN) confirming their drug likeliness. The findings indicate a high potential antidiarrheal impact that warrants further investigation for its therapeutic application.

Abstract
The rising burden of antimicrobial resistance and increasing infectious disease outbreaks, including the recent COVID-19 pandemic, has led to a growing demand for the development of natural products as a valuable source of leading medicinal compounds. There is a wide variety of active constituents found in plants, making them an excellent source of antimicrobial agents with therapeutic potential as alternatives or potentiators of antibiotics. The structural diversity of phytochemicals enables them to act through a variety of mechanisms, targeting multiple biochemical pathways, in contrast to traditional antimicrobials. Moreover, the bioactivity of the herbal extracts can be explained by various metabolites working in synergism, where hundreds to thousands of metabolites make up the extract. Although a vast amount of literature is available regarding the use of these herbal extracts against bacterial and viral infections, critical assessments of their quality are lacking. This review aims to explore the efficacy and antimicrobial effects of herbal extracts against clinically relevant gastrointestinal infections including pathogenic Escherichia coli, toxigenic Clostridioides difficile, Campylobacter and Salmonella species. The review will discuss research gaps and propose future approaches to the translational development of plant-derived products for drug discovery purposes for the treatment and prevention of gastrointestinal infectious diseases.

Antidiarrheal activity of the extracts of Valeriana jatamansi Jones on castor oil-induced diarrhea mouse by regulating multiple signal pathways. JOURNAL OF ETHNOPHARMACOLOGY 2022; 298:115560. [PMID: 35863616 DOI: 10.1016/j.jep.2022.115560] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 07/10/2022] [Accepted: 07/13/2022] [Indexed: 06/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Valeriana jatamansi Jones, a traditional medicine, is used for various medicinal purposes worldwide. This species is popular for its gastro-protective properties and has been verified to exert antidiarrheal effects. Qiuxieling mixture, an oral liquid preparation used to treat diarrhea in children in clinical practice, was extracted from V. jatamansi Jones. AIM OF THE STUDY Although Qiuxieling mixture has a good preventive effect on diarrhea children, the disgusting smell makes it intolerable. Therefore, we extracted odorless products from V. jatamansi Jones and Qiuxieling mixture. The present study is aimed to investigate the protective effects of two ethanolic extracts of V. jatamansi Jones and Qiuxieling mixture against castor oil-induced diarrhea and their possible mechanisms in mice. MATERIALS AND METHODS The two extracts of V. jatamansi Jones and Qiuxieling mixture were detected by HPLC. A castor oil-induced diarrheal model was used to evaluate the antidiarrheal effects. The expression of Occludin in the small intestine was measured by IHC. Western blotting and immunofluorescence were used to detect the expression of proteins related to the oxidative stress and GSDMD-mediated pyroptosis signaling pathways. ELISA was used to detect the expression of IL-6 and IL-1β in the small intestine of mice with diarrhea. RESULTS The two extracts of V. jatamansi Jones and Qiuxieling mixture dose-dependently reduced the diarrhea index and the diarrhea rate, delayed the onset of diarrhea, and decreased the weight of the intestinal content. Meanwhile, they reversed the decreased expression of Occludin and restored the activity of Na+-K+-ATPase in the intestines of diarrheal mice. In addition, they reversed the depletion of GSH, attenuated the activation of the ERK/JNK pathway, promoted the Nrf2/SOD1 signaling pathways, and decreased the release of ROS in the intestines of diarrheal mice. Moreover, they suppressed GSDMD-mediated pyroptosis by downregulating the NLRP3/caspase-1/GSDMD signaling pathway. CONCLUSIONS The two extracts of V. jatamansi Jones and Qiuxieling mixture exerted protective effects on castor oil-induced diarrhea in mice through a variety of mechanisms, including antioxidant stress, restoration of tight junctions between intestinal mucosal cells and regulation of the GSDMD-mediated pyroptosis pathway.

Abstract
OBJECTIVE To evaluate the antidiarrheal effect of ethanol extract of Glycyrrhiza uralensis Fisch root (GFR) in vivo and jejunal contraction in vitro. METHODS In vivo, 50 mice were divided into negative control, positive control (verapamil), low-, medium- and high-dose GFR (250, 500, 1,000 mg/kg) groups by a random number table, 10 mice in each group. The antidiarrheal activity was evaluated in castor oil-induced diarrhea mice model by evacuation index (EI). In vitro, the effects of GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) on the spontaneous contraction of isolated smooth muscle of rabbit jejunum and contraction of pretreated by Acetylcholine (ACh, 10 µmol/L) and KCl (60 mmol/L) were observed for 200 s. In addition, CaCl2 was accumulated to further study its mechanism after pretreating jejunal smooth muscle with GFR (1 and 3 g/L) or verapamil (0.03 and 0.1 µmol/L) in a Ca2+-free-high-K+ solution containing ethylene diamine tetraacetic acid (EDTA). RESULTS GFR (500 and 1,000 mg/kg) significantly reduced EI in castor oil-induced diarrhea model mice (P<0.01). Meanwhile, GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) inhibited the spontaneous contraction of rabbit jejunum (P<0.05 or P<0.01). Contraction of jejunums samples pretreated by ACh and KCl with 50% effective concentration (EC50) values was 1.05 (0.71-1.24), 0.34 (0.29-0.41) and 0.15 (0.11-0.20) g/L, respectively. In addition, GFR moved the concentration-effect curve of CaCl2 down to the right, showing a similar effect to verapamil. CONCLUSIONS GFR can effectively against diarrhea and inhibit intestinal contraction, and these antidiarrheal effects may be based on blocking L-type Ca2+ channels and muscarinic receptors.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 292:115186. [PMID: 35292376 DOI: 10.1016/j.jep.2022.115186] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 03/04/2022] [Accepted: 03/09/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In French Polynesia, many pathologies common or endemic to the territory cause diarrhea. This is the case for rotavirus gastroenteritis, salmonella food poisoning, ingestion of water contaminated by bacteria, and ciguatera. To treat these ailments, the population may employ traditional medicine for cultural reasons, geographical isolation, and poor health coverage. Polynesian remedies are often used without medical consultation and there is no data on their benefit-risk balance. A few ethnobotanical studies have been carried out in order to identify the traditional remedies used for various ailments, but few studies have focused on gastrointestinal pathologies. In this context, an ethnobotanical survey was carried out to identify treatments used for diarrhea and ciguatera, inventory the plants used, better understand the local representation of these remedies, and provide efficacy and safety data on these uses. MATERIALS AND METHODS From February to April 2021, a semi-structured survey was conducted on six islands in French Polynesia, including one island in the Windward Islands archipelago (Tahiti), three islands in the Marquesas archipelago (Hiva Oa, Nuku Hiva, Tahuata), and two islands in the Leeward Islands archipelago (Raiatea, Tahaa). A total of 133 people was interviewed including 34 specialists (of which 29 experts in herbalism). RESULTS These people mentioned the use of 27 plants for the treatment of diarrhea, and 24 for the treatment of ciguatera. Citrus aurantiifolia, Psidium guajava and Cordyline fruticosa were the three most cited plant species used for treating diarrhea, while Cocos nucifera, Punica granatum and Barringtonia asiatica were the most cited for ciguatera. A large majority of plants are widespread and introduced plants, which is congruent with the history of Polynesian people. While some plants are well known for similar uses (e.g. Psidium guajava for diarrhea, Heliotropium arboreum for ciguatera), others are less well known and may present toxicity risks (e.g. Barringtonia asiatica for ciguatera). CONCLUSION Traditional Polynesian medicine is an integral part of the local culture so important to be preserved and valued. However, more pharmacological and toxicological studies are still needed to determine the benefit-risk balance of some of these remedies and to allow their official integration into the Polynesian health system.

Abstract
Membrane pan-assay interference compounds (PAINS) are a class of molecules that interact nonspecifically with lipid bilayers and alter their physicochemical properties. An early identification of these compounds avoids chasing false leads and the needless waste of time and resources in drug discovery campaigns. In this work, we optimized an in silico protocol on the basis of umbrella sampling (US)/molecular dynamics (MD) simulations to discriminate between compounds with different membrane PAINS behavior. We showed that the method is quite sensitive to membrane thickness fluctuations, which was mitigated by changing the US reference position to the phosphate atoms of the closest interacting monolayer. The computational efficiency was improved further by decreasing the number of umbrellas and adjusting their strength and position in our US scheme. The inhomogeneous solubility-diffusion model (ISDM) used to calculate the membrane permeability coefficients confirmed that resveratrol and curcumin have distinct membrane PAINS characteristics and indicated a misclassification of nothofagin in a previous work. Overall, we have presented here a promising in silico protocol that can be adopted as a future reference method to identify membrane PAINS.

Antidiarrheal Effect of 80% Methanol Extract and Fractions of the Leaves of Ocimum lamiifolium in Swiss Albino Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:6838295. [PMID: 35664936 PMCID: PMC9162844 DOI: 10.1155/2022/6838295] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 03/17/2022] [Accepted: 05/18/2022] [Indexed: 11/18/2022]
Abstract
Introduction Worldwide, in children of under five years of age, diarrhea is responsible for more than 760,000 annual deaths. It is treated with both modern drugs and traditional medicinal plants, including O. lamiifolium. But the use of this plant as an antidiarrheal agent is not scientifically validated. Therefore, this study was aimed to evaluate antidiarrheal efficacy of the plant. Method The leaf powder was macerated by 80% methanol and then fractionated using n-hexane, n-butanol, and distilled water. Antidiarrheal activity was evaluated through different models (castor oil-induced diarrhea, enteropooling, and motility) using onset, number of wet feces, fluid content, weight and volume of intestinal content, and motility as test parameters by administering treatment doses to groups of mice. Group I received 10 mL/kg of the dissolving vehicle, Group II received either loperamide or atropine, and Groups III-V received extract doses of 100, 200, and 400 mg/kg, respectively. One-way ANOVA was used to analyze the data, followed by Tukey's post-hoc test. Results The crude extract exhibited a significant effect on the fluid content of feces at all tested doses. Additionally, the n-butanol and distilled water fractions revealed significant effects on onset of diarrhea at 400 mg/kg (p < 0.05), while the n-hexane fraction showed significant effects on number of wet feces, onset, and fluid content of feces at all tried doses. The crude extract and all the fractions (at 200 and 400 mg/kg) decreased the weight and volume of intestinal content significantly. Similarly, both the crude extract and distilled water fraction at 400 mg/kg as well as n-butanol and n-hexane fractions at 200 and 400 mg/kg showed meaningful differences on peristaltic index as compared to the negative control. Conclusion The results revealed that the leaf extract of O. lamiifolium has an antidiarrheal activity, which supports the traditional medical practice.

Abstract
Background Withaniasomnifera is an important medicinal plant for the treatment of diarrhea in Ethiopian folklore medicine. The aim of this study was to evaluate the antidiarrheal activity of Withania somnifera leaves in Swiss albino mice. Materials and Methods Hydromethanolic crude extraction and solvent fractionation were done using cold maceration technique. 80% methanol was used as a solvent in crude extraction, while distilled water, n-butanol, and chloroform were employed during fractionation. Castor oil-induced diarrhea, enteropooling, and gastrointestinal motility models were employed to evaluate antidiarrheal activity. Mice were randomly divided into five groups (six mice per group): negative control, which received 2% Tween 80 in distilled water; positive control, which received 3 mg/kg loperamide; and three test groups (III, IV, and V), which were treated with 100 mg/kg, 200 mg/kg, and 400 mg/kg of crude extract and solvent fractions, respectively. Results The crude extract, aqueous, and n-butanol fractions significantly delayed the onset of diarrhea at 200 mg/kg and 400 mg/kg dose. There was a significant reduction in the number and weight of stools at all tested doses of the crude extract and aqueous fraction, and at 200 mg/kg and 400 mg/kg of n-butanol fraction. Significant reduction in volume and weight of intestinal contents was observed at all tested doses of the crude extract, and at 200 mg/kg and 400 mg/kg of aqueous and n-butanol fractions. All tested doses of the crude extract and 200 mg/kg and 400 mg/kg of the aqueous and n-butanol fractions significantly reduced the motility of charcoal meal. Conclusion This study demonstrated that the crude extract and solvent fractions of the Withania somnifera leaves have antidiarrheal activity and supported the folklore use of the plant.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:1345006. [PMID: 35222665 PMCID: PMC8872661 DOI: 10.1155/2022/1345006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 11/24/2021] [Accepted: 01/29/2022] [Indexed: 01/02/2023]
Abstract
Polyalthia suberosa (Roxb.) is a plant used to cure coughs, dysentery, fevers, joint aches, rheumatic pain, inflammation, and a variety of skin diseases. The aim of the study was to evaluate the ethyl acetate extract of Polyalthia suberosa (P. suberosa) leaves and their effects on mice for neuropharmacological, analgesic, and antidiarrheal activities. For neurological studies, the hole cross, hole board, open field, and thiopental sodium-induced sleep duration measurement methodologies were used. The castor oil-induced diarrhea inhibition test was used to assess antidiarrheal action, and the acetic acid-induced writhing inhibition test was used to determine analgesic effectiveness. The extract was given in doses of 250 and 500 mg kg−1 body weight. As a standard drug, diazepam at a dosage of 3 mg kg−1 was used. The extract was also given to groups, and sleep time was measured and recorded. The onset of the anxiolytic effect of the extract at both doses was found to be significant (p < 0.001), and sleep time increased to 273 minutes. For assessing analgesic activity, the extract along with standard diclofenac was administered and found to be 55.02 percent and 64.33 percent, respectively, for the extracts, and diclofenac was found to be 67.44 percent (p < 0.001). For antidiarrheal activity, it was compared with the standard drug, loperamide. The decrease for plant extracts was 50.07 percent and 70.06 percent at 250 mg kg−1 and 500 mg kg−1, respectively, whereas it was 85.01 percent for loperamide (3 mg kg−1) (p < 0.00). In this study, it was found that ethyl acetate extract of Polyalthia suberosa leaves had strong CNS depressant, analgesic, and antidiarrheal activities, which indicates that it may be used in contemporary medicine.

Searching for plant-derived antivirals against dengue virus and Zika virus. Virol J 2022; 19:31. [PMID: 35193667 PMCID: PMC8861615 DOI: 10.1186/s12985-022-01751-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Accepted: 01/23/2022] [Indexed: 12/21/2022] Open
Abstract
Background The worldwide epidemics of diseases as dengue and Zika have triggered an intense effort to repurpose drugs and search for novel antivirals to treat patients as no approved drugs for these diseases are currently available. Our aim was to screen plant-derived extracts to identify and isolate compounds with antiviral properties against dengue virus (DENV) and Zika virus (ZIKV).
Methods Seven thousand plant extracts were screened in vitro for their antiviral properties against DENV-2 and ZIKV by their viral cytopathic effect reduction followed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method, previously validated for this purpose. Selected extracts were submitted to bioactivity-guided fractionation using high- and ultrahigh-pressure liquid chromatography. In parallel, high-resolution mass spectrometric data (MSn) were collected from each fraction, allowing compounds into the active fractions to be tracked in subsequent fractionation procedures. The virucidal activity of extracts and compounds was assessed by using the plaque reduction assay. EC50 and CC50 were determined by dose response experiments, and the ratio (EC50/CC50) was used as a selectivity index (SI) to measure the antiviral vs. cytotoxic activity. Purified compounds were used in nuclear magnetic resonance spectroscopy to identify their chemical structures. Two compounds were associated in different proportions and submitted to bioassays against both viruses to investigate possible synergy. In silico prediction of the pharmacokinetic and toxicity (ADMET) properties of the antiviral compounds were calculated using the pkCSM platform. Results We detected antiviral activity against DENV-2 and ZIKV in 21 extracts obtained from 15 plant species. Hippeastrum (Amaryllidaceae) was the most represented genus, affording seven active extracts. Bioactivity-guided fractionation of several extracts led to the purification of lycorine, pretazettine, narciclasine, and narciclasine-4-O-β-D-xylopyranoside (NXP). Another 16 compounds were identified in active fractions. Association of lycorine and pretazettine did not improve their antiviral activity against DENV-2 and neither to ZIKV. ADMET prediction suggested that these four compounds may have a good metabolism and no mutagenic toxicity. Predicted oral absorption, distribution, and excretion parameters of lycorine and pretazettine indicate them as candidates to be tested in animal models. Conclusions Our results showed that plant extracts, especially those from the Hippeastrum genus, can be a valuable source of antiviral compounds against ZIKV and DENV-2. The majority of compounds identified have never been previously described for their activity against ZIKV and other viruses.

Abstract
BACKGROUND This study investigated the antidiarrheal potential of the aqueous extract (AECR) and hydroalcoholic extract of Campomanesia reitziana leaves (HECR), its ethyl acetate (EAF) and dichloromethane fractions (DCMF), and myricitrin isolated from EAF. METHODS The total phenols and flavonoids were measured, followed by chromatography and myricitrin isolation. The 2,2-diphenyl-1-picryl-hydrazyl scavenger activity, the cytotoxicity, and the effects on LPS-induced nitrite production in intestinal epithelial cells (IEC-6) were quantified. The effect of HECR, EAF, DCMF, and AECR on intestinal motility (IT), gastric emptying (GE), and castor oil-induced diarrhea in mice was determined, as well as its antimicrobial activity. KEY RESULTS The administration of AECR 10% (10 ml/kg, p.o), but not HECR (300 mg/kg), reduced the GE and IT by 52 and 51%. The EAF and DCMF at 300 mg/kg also reduced IT but did not change GE. Moreover, AECR and EAF, but not DCMF, inhibited the castor oil-induced diarrhea and naloxone or metoclopramide pretreatment did not change these effects. Myricitrin did not change IT and the evacuation index of mice. Finally, the dry residue of AECR inhibited bacterial growth and EAF showed bacteriostatic activity against S. aureus, E. coli, and S. typhimurium and antifungal for C. albicans. However, none of the preparations alter the viability of Giardia spp. trophozoites. CONCLUSIONS The AECR and EAF can be effective to treat diarrhea acting through opioid- or dopaminergic type 2 receptor-independent mechanisms and by its antimicrobial actions.

Abstract
BACKGROUND Globally in 2019, diarrhea was the second leading cause of mortality in children, accounting for more than half a million under-five deaths yearly. Several societies use Coffea arabica Linn for the treatment of diarrhea. However, its use is not scientifically validated. OBJECTIVE The study was conducted to evaluate antidiarrheal activity of 80% methanol extract and solvent fractions of roasted seed of Coffea arabica Linn in mice. METHODS Coffea arabica Linn seed was roasted, milled, extracted, and fractionated using hexane, ethyl acetate, and distilled water. Castor oil-induced diarrhea, enteropooling, and motility tests were conducted. Effects on onset, number of feces, weight of feces, fluid content, volume and weight of intestinal content, and motility were evaluated by administering 100 mg/kg, 200 mg/kg, and 400 mg/kg of each extract. Negative controls received 10 ml/kg of the vehicle, and positive controls received either loperamide (3 mg/kg) or atropine (1 mg/kg). Data were analyzed using one-way ANOVA followed by Tukey's post hoc test. RESULTS Ethyl acetate fraction at all tested doses significantly prolonged (p < 0.05) onset of diarrhea. The number and weight of feces were also reduced significantly by crude extract and ethyl acetate fraction. Reduction in fluid content was observed at 200 mg/kg and 400 mg/kg of the crude extract (p < 0.01) and aqueous fraction (p < 0.001) as well as all tested doses of ethyl acetate fraction (p < 0.001). Similarly, the crude extract, ethyl acetate fraction, and aqueous fraction showed a significant reduction in the volume and weight of intestinal content. At 400 mg/kg, the crude extract, hexane fraction, aqueous fraction, and all doses of ethyl acetate fraction showed significant antimotility activity. CONCLUSION The results of this study revealed that the roasted seed of Coffea arabica Linn has antidiarrheal activity.

Abstract
Introduction In Ethiopia, different medicinal plants have been claimed and used to treat diarrheal diseases. However, these claimed effects for most medicinal plants have not been scientifically verified. One of such plants in Ethiopian folkloric medicine is Moringa stenopetala, which is usually consumed as a vegetable in southern Ethiopia. Thus, this study aimed to evaluate the antidiarrheal and antisecretory effects of 80% methanolic leaf extract of Moringa stenopetala in different mice models. Method Using Swiss albino mice, castor oil-induced diarrhea, charcoal meal-based gastrointestinal motility, and castor oil-induced secretion models were employed to assess antidiarrheal activity. In all of the test models, animals were randomly assigned into five groups consisting of six animals in each group. Group I received 0.5 ml of the vehicle (2% tween-80), while group II was treated with standard drug (3 mg/kg loperamide) in the respective models, whereas groups III to V received 150, 300, and 450 mg/kg of the methanolic leaf extracts of Moringa stenopetala. Onset, frequency, consistency, and weight of stool (diarrhea) were recorded, and different parameters and percentage proportions were calculated. Data were analyzed using one-way ANOVA followed by Tukey's test, and p < 0.05 was considered statistically significant at 95% confidence of interval. Result In the castor oil-induced diarrheal model, the percentage inhibition of diarrhea was 48.5, 58.6, and 60% for the respective doses of 150, 300, and 450 mg/kg of the extract. And, the extract showed a 36.8, 54.4, and 55.9% reduction of peristalsis in charcoal meal-based gastrointestinal motility test compared to the negative control group. Moreover, in the antisecretory assay, the 150, 300, and 450 mg/kg doses of MEMS inhibited fluid contents of the stool by 11.5, 54.54, and 61.82%, respectively, relative to the vehicle-treated group. Conclusion The findings revealed that the 80% methanolic leaf extract of Moringa stenopetala extract has shown antidiarrheal activity.

Abstract
Tannic Acid (TA) is a naturally occurring antioxidant polyphenol that has gained popularity over the past decade in the field of biomedical research for its unique biochemical properties. Tannic acid, typically extracted from oak tree galls, has been used in many important historical applications. TA is a key component in vegetable tanning of leather, iron gall ink, red wines, and as a traditional medicine to treat a variety of maladies. The basis of TA utility is derived from its many hydroxyl groups and its affinity for forming hydrogen bonds with proteins and other biomolecules. Today, the study of TA has led to the development of many new pharmaceutical and biomedical applications. TA has been shown to reduce inflammation as an antioxidant, act as an antibiotic in common pathogenic bacterium, and induce apoptosis in several cancer types. TA has also displayed antiviral and antifungal activity. At certain concentrations, TA can be used to treat gastrointestinal disorders such as hemorrhoids and diarrhea, severe burns, and protect against neurodegenerative diseases. TA has also been utilized in biomaterials research as a natural crosslinking agent to improve mechanical properties of natural and synthetic hydrogels and polymers, while also imparting anti-inflammatory, antibacterial, and anticancer activity to the materials. TA has also been used to develop thin film coatings and nanoparticles for drug delivery. In all, TA is fascinating molecule with a wide variety of potential uses in pharmaceuticals, biomaterials applications, and drug delivery strategies.

Abstract
The development of multifunctional biomaterials as both tissue regeneration and drug delivery devices is currently a major focus in biomedical research. Tannic Acid (TA), a naturally occurring plant polyphenol, displays unique medicinal abilities as an antioxidant, an antibiotic, and as an anticancer agent. TA has applications in biomaterials acting as a crosslinker in polymer hydrogels improving thermal stability and mechanical properties. We have developed injectable cell seeded collagen beads crosslinked with TA for breast reconstruction and anticancer activity following lumpectomy. This study determined the longevity of the bead implants by establishing a degradation time line and TA release profile in vivo. Beads crosslinked with 0.1% TA and 1% TA were compared to observe the differences in TA concentration on degradation and release. We found collagen/TA beads degrade at similar rates in vivo, yet are resistant to complete degradation after 16 weeks. TA is released over time in vivo through diffusion and cellular activity. Changes in mechanical properties in collagen/TA beads before implantation to after 8 weeks in vivo also indicate loss of TA over a longer period of time. Elastic moduli decreased uniformly in both 0.1% and 1% TA beads. This study establishes that collagen/TA materials can act as a drug delivery system, rapidly releasing TA within the first week following implantation. However, the beads retain TA long term allowing them to resist degradation and remain in situ acting as a cell scaffold and tissue filler. This confirms its potential use as an anticancer and minimally invasive breast reconstructive device following lumpectomy.

Evaluation of Antidiarrheal Activity of 80% Methanolic Extract of the Leaves of Cordia africana (Lamiaceae) in Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:3627878. [PMID: 34873407 PMCID: PMC8643234 DOI: 10.1155/2021/3627878] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Revised: 10/29/2021] [Accepted: 11/06/2021] [Indexed: 11/26/2022]
Abstract
Background Diarrheal disease is a major cause of morbidity and mortality throughout the world, particularly in developing countries. Currently available drugs are linked with adverse effects, contraindications, and risk of resistance. Traditionally, the leaf concoction of Cordia africana is claimed to be used for diarrhea. However, the safety and efficacy of the leaf extract have not been scientifically approved yet. Therefore, the study was conducted to validate its antidiarrheal activity and safety profile in mice. Method The hydromethanolic extract was obtained by the cold maceration technique in 80% methanol. Phytochemical screening tests were done for secondary metabolites by using standard tests. The antidiarrheal activity of the test extract at the doses of 100, 200, and 400 mg/kg was evaluated by using castor oil-induced diarrheal, gastrointestinal transit, and enteropooling models in mice. Result In an acute toxicity study, there were no visible signs of toxicity and mortality following a single oral administration of 2000 mg/kg. Phytochemical screening tests revealed the presence of alkaloids, saponins, flavonoids, terpenoids, phenols, and tannins. The hydromethanolic extract significantly prolonged the onset of diarrhea and reduced the weight of wet and total feces at 100 (P < 0.01), 200 (P < 0.001), and 400 mg/kg (P < 0.001) in the castor oil-induced diarrheal model. However, in the gastrointestinal transit model, a significant (P < 0.001) reduction in the charcoal meal travel was observed in the middle (200 mg/kg) and higher (400 mg/kg) test doses. Similarly, the extract produced a significant (P < 0.001) reduction in the weight and volume of intestinal contents at the aforementioned doses. Conclusion The study demonstrated that the test extract showed promising antidiarrheal activity. Hence, this study supports its antidiarrheal use in Ethiopian folklore medicine.

In Vitro Selective Antibacterial and Antiproliferative Effects of Ethanolic Extracts from Cambodian and Philippine Plants Used in Folk Medicine for Diarrhea Treatment. Front Pharmacol 2021; 12:746808. [PMID: 34899301 PMCID: PMC8661004 DOI: 10.3389/fphar.2021.746808] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Accepted: 10/08/2021] [Indexed: 12/12/2022] Open
Abstract
Bacterial diarrhea remains a global health problem, especially in developing tropical countries. Moreover, dysbiosis caused by diarrheagenic bacteria and inappropriate antimicrobial treatment has been associated with intestinal carcinogenesis. Despite the rich tradition of the use of herbs for the treatment of gastrointestinal disorders in Cambodian and Philippine folk medicine, many of them have not yet been systematically studied for their in vitro selective inhibitory effects on intestinal bacteria and cells. In the present study, in vitro inhibitory activities of 35 ethanolic extracts derived from 32 Cambodian and Philippine medicinal plants were determined by broth microdilution method against 12 pathogenic bacteria. Furthermore, cytotoxicity against intestinal cancer cells (Caco-2 and HT-29) using thiazolyl blue tetrazolium bromide cytotoxicity assay and safety to six beneficial intestinal bacteria (bifidobacteria and lactobacilli) and intestinal normal cells (FHs 74 Int) were determined for the antimicrobially active extracts. Selectivity indices (SIs) were calculated among the averages of minimum inhibitory concentrations (MICs), half-maximal inhibitory concentrations (IC50), and 80% inhibitory concentrations of proliferation (IC80) for each type of the tested agents. The extracts of Artocarpus blancoi (Elmer) Merr. (Moraceae), Ancistrocladus tectorius (Lour.) Merr. (Ancistrocladaceae), and Pentacme siamensis (Miq.) Kurz (Dipterocarpaceae) produced significant growth-inhibitory effects (MICs = 32-512 μg/ml) against intestinal pathogenic bacteria at the concentrations nontoxic to normal intestinal cells (IC80 values >512 μg/ml; SIs = 0.11-0.2). Moreover, the extract of P. siamensis (Miq.) Kurz was relatively safe to beneficial bacteria (MICs ≥512 μg/ml; SI = 0.1), and together with A. blancoi (Elmer) Merr., they selectively inhibited intestinal cancer cells (IC50 values ≥51.98 ± 19.79 μg/ml; SIs = 0.3 and 0.6). Finally, a strong selective antiproliferative effect on cancer cells (IC50 values 37.89 ± 2.68 to 130.89 ± 13.99 μg/ml; SIs = 0.5) was exerted by Ehretia microphylla Lam. (Boraginaceae), Lagerstroemia cochinchinensis Pierre ex Gagnep. (Lythraceae), and Melastoma saigonense (Kuntze) Merr. (Melastomataceae) (leaves with flower buds). The results suggest that the above-mentioned species are promising materials for the development of new selective antibacterial and antiproliferative agents for the treatment of infectious diarrhea and associated intestinal cancer diseases. However, further research is needed regarding the isolation and identification of their active constituents.

Frontiers in antibiotic alternatives for Clostridioides difficile infection. World J Gastroenterol 2021; 27:7210-7232.

Abstract
Clostridioides difficile (C. difficile) is a gram-positive, anaerobic spore-forming bacterium and a major cause of antibiotic-associated diarrhea. Humans are naturally resistant to C. difficile infection (CDI) owing to the protection provided by healthy gut microbiota. When the gut microbiota is disturbed, C. difficile can colonize, produce toxins, and manifest clinical symptoms, ranging from asymptomatic diarrhea and colitis to death. Despite the steady-if not rising-prevalence of CDI, it will certainly become more problematic in a world of antibiotic overuse and the post-antibiotic era. C. difficile is naturally resistant to most of the currently used antibiotics as it uses multiple resistance mechanisms. Therefore, current CDI treatment regimens are extremely limited to only a few antibiotics, which include vancomycin, fidaxomicin, and metronidazole. Therefore, one of the main challenges experienced by the scientific community is the development of alternative approaches to control and treat CDI. In this Frontier article, we collectively summarize recent advances in alternative treatment approaches for CDI. Over the past few years, several studies have reported on natural product-derived compounds, drug repurposing, high-throughput library screening, phage therapy, and fecal microbiota transplantation. We also include an update on vaccine development, pre- and pro-biotics for CDI, and toxin antidote approaches. These measures tackle CDI at every stage of disease pathology via multiple mechanisms. We also discuss the gaps and concerns in these developments. The next epidemic of CDI is not a matter of if but a matter of when. Therefore, being well-equipped with a collection of alternative therapeutics is necessary and should be prioritized.

Abstract
Diarrhea, often caused by microorganisms, has been associated with high morbidity and mortality in Africa. Increased rates of antimicrobial-resistant pathogens have reignited the quest for alternative therapies. This review aimed at identifying medicinal plants used in the treatment of human diarrheal cases in Rwanda and analyzing their ethnobotany, ethnopharmacology, and phytochemistry. We searched PubMed/Medline, Google Scholar, ScienceDirect, and the Web of Science for published articles on medicinal plants used to treat diarrhea in Rwanda. Additionally, specialized herbarium documents of different institutes were reviewed. Articles were assessed for relevance, quality, and taxonomical accuracy before being included in this review. Overall, 63 species of medicinal plants belonging to 35 families were recorded. Asteraceae was the predominant family with six species, followed by Fabaceae and Lamiaceae, with five species each. The most reported species with anti-diarrheal properties were Vernonia amygdalina Delile, Tetradenia riparia (Hochst.) Codd, Clerodendrum myricoides R. Br. and Chenopodium ugandae (Aellen) Aellen. Leaves (66.7%) and roots (17.5%) were the commonly used plant parts in the preparation of medicine. Phytochemicals from medicinal plants with antidiarrheic activities were sesquiterpene lactones (V. amygdalina); terpene, sterols, saponosides, and flavonoids (C. ugandae); saponins and tannins (T. riparia); and tannins, flavonoids, and alkaloids (C. myricoides). Six studies tested the antimicrobial activities of the plants against bacteria and viruses known to cause diarrhea. Erythrina abyssinica, Euphorbia tirucalli, Dracaena afromontana, and Ficus thonningii are socio-culturally important. Further research on toxicity and posology is needed to ensure the safety of medicinal plants.

Abstract
In spite of the immense advancement in the diagnostic and treatment modalities, cancer continues to be one of the leading causes of mortality across the globe, responsible for the death of around 10 million patients every year. The foremost challenges faced in the treatment of this disease are chemoresistance, adverse effects of the drugs, and the high cost of treatment. Though scientific studies over the past few decades have foreseen and are focusing on the cancer-preventive and therapeutic potential of natural products and their underlying mechanism of action, many more of these agents are not still explored. Piperlongumine (PL), or piplartine, is one such alkaloid isolated from Piper longum Linn. which is shown to be safe and has significant potential in the prevention and therapy of cancer. Numerous shreds of evidence have established the ability of this alkaloid and its analogs and nanoformulations in modulating various complex molecular pathways such as phosphatidylinositol-3-kinase/protein kinase B /mammalian target of rapamycin, nuclear factor kappa-B, Janus kinases/signal transducer and activator of transcription 3, etc. and inhibit different hallmarks of cancer such as cell survival, proliferation, invasion, angiogenesis, epithelial-mesenchymal-transition, metastases, etc. In addition, PL was also shown to inhibit radioresistance and chemoresistance and sensitize the cancer cells to the standard chemotherapeutic agents. Therefore, this compound has high potential as a drug candidate for the prevention and treatment of different cancers. The current review briefly reiterates the anti-cancer properties of PL against different types of cancer, which permits further investigation by conducting clinical studies.

Abstract
Background Diarrhea is a common health problem worldwide, especially in developing countries. It is the second leading cause of mortality for children. Uncaria gambir Roxb. extract has been used to treat diarrhea and dysentery, and as an astringent medicine, in Asian countries. Here, we investigated the antidiarrheal effect of DLBS1Y62, which is the bioactive fraction of dried sap extract from U. gambir, using castor oil-induced diarrhea and castor oil-induced enteropooling in rats. Methods DLBS1Y62 was obtained by crushing and milling the dried sap extract of U. gambir leaves. Male Wistar rats, 2–3 months old, weighing 200–250 g (n=30), were used for this study. Negative controls received 0.05 mL purified water. Positive controls were treated with 2 mg/kg BW loperamide orally as a suspension. Groups I, II, and III received 6.25, 12.5, and 25 mg/kg BW DLBS1Y62, respectively. Group IV received a combination of 6.25 mg/kg BW DLBS1Y62 and 20 mg/kg BW attapulgite. Diarrheal onset and frequency were observed; then, the weight and volume of intestinal contents were measured. Results DLBS1Y62 at all dose levels and in combination with attapulgite could inhibit the formation of further fecal forms of diarrhea, without delaying the onset of diarrhea. The rats that received DLBS1Y62 25 mg/kg BW had the lowest frequency of diarrhea and average intestinal contents compared with the treatment and negative control groups. DLBS1Y62 at a dose of 25 mg/kg BW also gave similar results to 2 mg/kg BW loperamide as a positive control in reducing diarrheal frequency and intestinal content. Conclusion The results of this study suggest that DLBS1Y62, particularly at a dose of 25 mg/kg BW, containing tannin as a compound, may become an alternative treatment for diarrhea.

Abstract
This study evaluated anti-bacterial, anti-diarrheal, and cytotoxic activities of ten edible fruits (Aegiceras corniculatum, Avicennia officinalis, Bruguiera gymnorrhiza, Ceriops decandra, Heritiera fomes, Nypa fruticans, Phoenix paludosa, Sarcolobusglobosus, Sonneratia caseolaris, and Xylocarpus mekongensis) in the Sundarbans mangrove forest of Bangladesh. Highest antibacterial activity was shown for ethanol:methanol (1:1) extracts of S. caseolaris (2 mg/disc), which demonstrated inhibition zones of 16.7, 17.0, 14.7, 15.7, and 15.7 mm against Escherichia coli, Klebsiella sp., Shigella boydii, Shigella sonnei, and Staphylococcus aureus, respectively. In mice with castor oil-induced diarrhea, S. caseolaris extract (250 mg/kg body weight) showed the highest inhibition (87.7%) and delayed the onset time (273 min) of diarrheal episodes, followed by A. corniculatum extract (inhibition, 83.6%; delayed onset time, 187.4 min). S. caseolaris and A. corniculatum fruit powders were successively fractionated into n-hexane, diethyl ether, chloroform, ethanol, and methanol. Antidiarrheal activity significantly increased with increasing polarity of these fractions. In brine shrimp lethality assay, S. globosus extract demonstrated the highest cytotoxicity (59.2 μg/mL), followed by H. fomes (74.1 μg/mL) and C. decandra (116.7 μg/mL); however, lowest cytotoxicity was shown for A. corniculatum, A. officinalis, and S. caseolaris extracts. Mice treated with A. corniculatum extract did not experience any acute toxicity. These results demonstrate that S. caseolaris and A. corniculatum fruits have potential to treat diarrhea and may act as useful nutraceuticals.

Abstract
Indigenous trade of medicinal plants in South Africa is a multi-million-rand industry and is still highly relevant in terms of primary health care. The purpose of this study was to identify today's most traded medicinal barks, traditionally and contemporaneously used for dermatological, gastrointestinal, and respiratory tract infections; then, to investigate the antimicrobial activity and toxicity of the respective extracts and interpret outcomes in light of pharmacokinetics. Thirty-one popularly traded medicinal barks were purchased from the Faraday and Kwa Mai-Mai markets in Johannesburg, South Africa. Information on the medicinal uses of bark-based medicines in modern commerce was recorded from randomly selected traders. The minimum inhibitory concentration (MIC) method was used for antimicrobial screening, and brine shrimp lethality was used to determine toxicity. New medicinal uses were recorded for 14 bark species. Plants demonstrating some broad-spectrum activities against tested bacteria include Elaeodendron transvaalense, Erythrina lysistemon, Garcinia livingstonei, Pterocelastrus rostratus, Rapanea melanophloeos, Schotia brachypetala, Sclerocarya birrea, and Ziziphus mucronata. The lowest MIC value of 0.004 mg/mL was observed against Staphylococcus epidermidis for a dichloromethane bark extract of E. lysistemon. The tested medicinal barks were shown to be non-toxic against the Artemia nauplii (brine shrimp) bioassay, except for a methanol extract from Trichilia emetica (69.52% mortality). Bacterial inhibition of bark extracts with minimal associated toxicity is consistent with the safety and valuable use of medicinal barks for local muthi market customers. Antimicrobial outcomes against skin and gastrointestinal pathogens are feasible because mere contact-inhibition is required in vivo; however, MIC values against respiratory pathogens require further explaining from a pharmacokinetics or pharmacodynamics perspective, particularly for ingested rather than smoked therapies.

Abstract
Psidium guajava (L.) belongs to the Myrtaceae family and it is an important fruit in tropical areas like India, Indonesia, Pakistan, Bangladesh, and South America. The leaves of the guava plant have been studied for their health benefits which are attributed to their plethora of phytochemicals, such as quercetin, avicularin, apigenin, guaijaverin, kaempferol, hyperin, myricetin, gallic acid, catechin, epicatechin, chlorogenic acid, epigallocatechin gallate, and caffeic acid. Extracts from guava leaves (GLs) have been studied for their biological activities, including anticancer, antidiabetic, antioxidant, antidiarrheal, antimicrobial, lipid-lowering, and hepatoprotection activities. In the present review, we comprehensively present the nutritional profile and phytochemical profile of GLs. Further, various bioactivities of the GL extracts are also discussed critically. Considering the phytochemical profile and beneficial effects of GLs, they can potentially be used as an ingredient in the development of functional foods and pharmaceuticals. More detailed clinical trials need to be conducted to establish the efficacy of the GL extracts.

Abstract
Coronavirus disease 2019 (COVID-19) is a virulent viral disease that has now become a public health emergency of global significance and still without an approved treatment regimen or cure. In the absence of curative drugs and with vaccines development still in progress, alternative approaches to stem the tide of the pandemic are being considered. The potential of a phytotherapeutic approach in the management of the dreaded disease has gained attention, especially in developing countries, with several claims of the development of anti-COVID-19 herbal formulations. This is a plausible approach especially with the increasing acceptance of herbal medicine in both alternative and orthodox medical practices worldwide. Also, the established efficacy of herbal remedies in the treatment of numerous viral diseases including those caused by coronaviruses, as well as diseases with symptoms associated with COVID-19, presents a valid case for serious consideration of herbal medicine in the treatment of COVID-19. However, there are legitimate concerns and daunting challenges with the use of herbs and herbal products. These include issues of quality control, unethical production practice, inadequate information on the composition, use and mechanisms, weak regulatory policies, herb-drug interactions and adverse reactions, and the tendency for abuse. This review discusses the feasibility of intervention with herbal medicine in the COVID-19 pandemic and the need to take proactive measures to protect public health by improving the quality and safety of herbal medicine deployed to combat the disease.

BMC Complement Med Ther 2021; 21:84. [PMID: 33676495 PMCID: PMC7937208 DOI: 10.1186/s12906-021-03261-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2019] [Accepted: 02/24/2021] [Indexed: 01/04/2023] Open
Abstract
Background Enterotoxigenic Escherichia coli (ETEC) is classically associated with acute secretory diarrhea, which induces 2 million people death in developing countries over a year, predominantly children in the first years of life. Previously, tannins (47.75%) were extracted from Galla Chinensis and prepared as Galla Chinensis oral solution (GOS) which showed significant antidiarrheal activity in a castor oil-induced diarrhea in mice. Whether the tannins extract were also effective in treatment of ETEC-induced diarrhea was determined in this study. Methods Mice were randomly divided into 6 groups (n = 22). The mice in the normal and untreated groups were given normal saline. Three GOS-treated groups were received different concentrations of GOS (5, 10 and 15%, respectively) at a dose of 10 mL/kg. Mice in the positive control group were fed with loperamide (10 mg/kg). The treatment with GOS started 3 days before infection with ETEC and continued for 4 consecutive days after infection. On day 3, mice were all infected with one dose of LD50 of ETEC, except those in the normal group. Survival of mice was observed daily and recorded throughout the study. On days 4 and 7, samples were collected from 6 mice in each group. Results GOS could increase the survival rate up to 75%, while in the untreated group it is 43.75%. The body weights of mice treated with 15% GOS were significantly increased on day 7 in comparison with the untreated group and the normal group. GOS-treatment recovered the small intestine coefficient enhanced by ETEC-infection. The diarrhea index of mice treated with GOS was significantly decreased. GOS increased the levels of IgG and sIgA in the terminal ileum and decreased the levels of pro-inflammatory cytokines (IFN-γ, TNF-α, IL-1β, IL-6 and IL-8) in serum. GOS could increase the amount of intestinal probiotics, Lactobacilli and Bifidobacteria. GOS could alleviate colon lesions induced by ETEC-infection. GOS showed higher potency than loperamide. Conclusions GOS could be a promising drug candidate for treating ETEC infections.

Evaluation of In Vivo Antidiarrheal Activity of Solvent Fractions of Hagenia abyssinica (Rosaceae) in Swiss Albino Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:8828331. [PMID: 33628317 PMCID: PMC7896859 DOI: 10.1155/2021/8828331] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 02/03/2021] [Accepted: 02/04/2021] [Indexed: 12/11/2022]
Abstract
Background Ethiopia has several medicinal plants that have been used for their antidiarrheal activity. Hagenia abyssinica is the most commonly used medicinal plant for the management of diarrhea in Ethiopia. Thus, this study's aim is to investigate the antidiarrheal effect of solvent fractions of H. abyssinica. Methods Antidiarrheal activity of extract fractions obtained from different solvents was evaluated by using small intestine transit, enteropooling, and castor oil-induced diarrhea animal models. In all animal models, the solvent fractions treated groups were treated with three different doses (100 mg/kg, 200 mg/kg, and 400 mg/kg) of the solvent fractions, while the negative control group was treated with a vehicle (distilled water), and positive control group was treated with loperamide. Results The acute toxicity test revealed that the LD50 of H. abyssinica is > 2000 mg/kg. In castor oil-induced, the solvent fractions of H. abyssinica (at 200 mg/kg and 400 mg/kg) significantly (P < 0.05–0.001) prolonged the stool frequency, reduced the weight of feces, and delayed diarrheal onset time as compared with the negative control group. The fractions produced a significant (P < 0.05) antimotility effect at the doses of 200 mg/kg and 400 mg/kg as compared to the negative control. All solvent fractions at the middle and higher doses showed a statistically significant dose-dependent reduction in the volume of intestinal contents and weight of the feces. However, the solvent fractions of H. abyssinica at a dose of 100 mg/kg failed to produce a statistically significant activity in all parameters (number of wet feces, the onset of diarrhea, and number of total feces) when compared with the negative control group. Conclusion The extract fractions obtained from different solvents have shown significant antidiarrheal activity. Thus, this finding supports the claimed traditional use of H. abyssinica leaves for the treatment of diarrhea.

The Active Ingredients Identification and Antidiarrheal Mechanism Analysis of Plantago asiatica L. Superfine Powder. Front Pharmacol 2021; 11:612478. [PMID: 33542689 PMCID: PMC7851704 DOI: 10.3389/fphar.2020.612478] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 11/16/2020] [Indexed: 11/23/2022] Open
Abstract
Plantago asiatica L. is a natural medicinal plant that has been widely used for its various pharmacological effects such as antidiarrheal, anti-inflammatory, and wound healing. This study aims to explore the antidiarrheal active ingredients of Plantago asiatica L. that can be used as quality markers to evaluate P. asiatica L. superfine powder (PSP). Molecular docking experiment was performed to identify the effective components of P. asiatica L., which were further evaluated by an established mouse diarrhea model. Na+/K+-ATPase and creatine kinase (CK) activities and the Na+/K+ concentrations were determined. The gene expression of ckb and Atp1b3 was detected. PSP was prepared and evaluated in terms of the tap density and the angle of repose. The structures of PSPs of different sizes were measured by infrared spectra. The active ingredient contents of PSPs were determined by HPLC. The results indicated that the main antidiarrheal components of P. asiatica L. were luteolin and scutellarein that could increase the concentration of Na+ and K+ by upregulating the activity and gene level of CK and Na+/K+-ATPase. In addition, luteolin and scutellarein could also decrease the volume and weight of small intestinal contents to exert antidiarrheal activity. Moreover, as the PSP size decreased from 6.66 to 3.55 μm, the powder tended to be amorphous and homogenized and of good fluidity, the content of active compounds gradually increased, and the main structure of the molecule remained steady. The optimum particle size of PSP with the highest content of active components was 3.55 μm, and the lowest effective dose for antidiarrhea was 2,000 mg/kg. Therefore, the antidiarrheal active ingredients of PSP were identified as luteolin and scutellarein that exert antidiarrheal activity by binding with Na+/K+-ATPase. PSP was successfully prepared and could be used as a new dosage form for the diarrhea treatment.

Abstract
Introduction Diarrhea is a cause of morbidity and mortality, especially in children. Patients with diarrhea have been suffering from limited treatment options due to poor drug tolerance, side effect, and multi-drug resistance to almost all the current drug treatments. Therefore, it is important to search for a new therapeutic medicine that can effectively prevent the disease and safe. Vernonia amygdalina is an indigenous medicinal plant used traditionally for the treatment of diarrhea in Ethiopia. The aim of this study was therefore to confirm the antidiarrheal activities of 80% methanol leaves extract using mice models. Materials and Methods The antidiarrheal activities of the 80% methanol leaves extract were investigated using castor oil-induced diarrhea, intestinal motility, and enteropooling models in mice. The negative control received distilled water orally, the test groups received three dose levels (100, 200, and 400 mg/kg) of the plant materials, and the positive control is given 3 mg/kg Loperamide orally. Results In the castor oil-induced diarrheal model, the extract delayed onset of diarrhea and reduced fecal parameters at all tested doses significantly as compared with the negative control. Results from the charcoal meal test revealed that the extract produced a significant anti-motility effect at all tested doses as compared with the negative control. In the enteropooling test, the extract produced a significant decline in the volume and weight of intestinal contents. The observed antidiarrheal activity could be associated with the phytochemicals present in this plant extract. It was also observed that the extracts have shown no acute toxicity at a dose of 2 g/kg. Conclusion This study provides the antidiarrheal activity of the crude extract in all three models. Hence, the findings provide scientific support for the traditional use of Vernonia amygdalina leaves as treatment of diarrhea.

Abstract
Protea caffra is used as a diarrhoeal remedy in South African herbal medicine, however, its pharmacological properties remain largely unknown. In the present study, extracts from different Protea caffra organs were screened against drug-sensitive and -resistant diarrhoeagenic pathogens using the microdilution assay (minimum inhibitory concentration, MIC). Twig extracts (70% methanol, MeOH) of the plant were purified and the resultant fractions screened for antibacterial properties (MIC). The chemical profiles of the fractions were determined by Gas Chromatography-Mass Spectrometry (GC-MS), while ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) was used to quantify the phenolic acids in the plant. The mutagenic properties of bioactive extracts were assessed using the Ames test. The extracts demonstrated weak-moderate antibacterial properties (MIC: 0.3–0.6 mg/mL). A cold ethyl acetate fraction of MeOH twig extract exhibited significant antibacterial properties (MIC = 0.078 mg/mL) against Enterococcus faecalis. The presence of antibacterial compounds (1-adamantane carboxylic acid, heptacosanol, levoglucosan, nonadecanol) in the plant was putatively confirmed based on GC-MS analysis. Furthermore, UHPLC-MS/MS analysis revealed varying concentrations of phenolic acids (0.08–374.55 µg/g DW). Based on the Ames test, the extracts were non-mutagenic thereby suggesting their safety. To a certain degree, the current study supports the traditional use of Protea caffra to manage diarrhoea among local communities in South Africa.

Abstract
Background Tannic acid (TA) is potential to reduce diarrhea in weaning pigs, but knowledge about the influence of TA on intestinal barrier integrity and function is still scarce. This experiment was conducted to investigate the effects of dietary TA supplementation on growth performance, diarrhea rate, intestinal barrier integrity and function of weaned pigs. Methods A total of 108 crossbred (Duroc × Landrace × Yorkshire) piglets, with an initial average body weight of 6.60 ± 0.27 kg, were allotted to 3 groups (6 pigs/pen and 6 replicates/group) in a randomized complete block design according to their gender and body weight. Piglets were fed the basal diet with 0 (control, CON), 0.2% and 1.0% TA, respectively. The trial lasted for 28 d. Results Compared with the CON group, dietary 0.2% and 1.0% TA supplementation didn’t affect ADFI, ADG and F:G (P > 0.05), but reduced diarrhea rate, diarrhea index and diarrhea score of piglets (P < 0.05), reduced diamine oxidase (DAO) activity and D-lactic acid concentration in serum (P < 0.01). The higher occludin expression and localization were observed in the duodenum, jejunum and ileum after supplementation with 0.2% or 1.0% TA (P < 0.05). Adding 0.2% TA to diet significantly decreased crypt depth, increased villus height/crypt depth ratio in the duodenum (P < 0.05), and dietary 1.0% TA tended to decrease crypt depth (P < 0.10) and significantly decreased villus height (P < 0.05) of the ileum. Moreover, lower malondialdehyde content in the ileum was detected in the pigs fed 1.0% TA (P < 0.05). In the duodenum, both 0.2% and 1.0% TA groups had higher occludin (OCLN) mRNA and 0.2% TA group had higher zonula occludens-2 (ZO-2) level (P < 0.05). Meanwhile, dietary 1.0% TA supplementation tended to up-regulate OCLN mRNA levels in the jejunum (P < 0.10) and 0.2% TA supplementation tended to up-regulate zonula occludens-1 (ZO-1) mRNA levels in the ileum (P < 0.10). Conclusion In conclusion, dietary supplementation of 0.2% or 1.0% TA could effectively alleviate post-weaning diarrhea without altering growth performance in weaned piglets, which might be achieved by improving intestinal barrier integrity and function.

Abstract
BACKGROUND Diarrhoea has been the major cause of death especially in children of developing countries. Brucea antidysenterica is one of the several medicinal plants used traditionally for the treatment of diarrhoea in Ethiopia. Hence, the present study was undertaken to investigate the antidiarrhoeal and antibacterial activities of the root extract of B. antidysenterica. METHODS Plant material was extracted by maceration technique using 80% methanol. The antidiarrhoeal activity was tested using castor oil-induced diarrhoea, castor oil-induced charcoal meal test, and castor oil-induced enteropooling models in mice. Whilst, the antibacterial activity of the crude extract was evaluated using agar well diffusion and broth microdilution methods. RESULTS The 80% methanolic crude extract significantly delayed the diarrhoeal onset at the two higher doses (p < 0.001) and it has also inhibited the number and weight of faecal output at all tested doses as compared with the negative control. Moreover, it showed a significant anti-motility effect (p < 0.001) at all tested doses. Whereas it displayed a significant reduction in the weight and volume of intestinal contents at the doses of 200 and 400 mg/kg (p < 0.01). The highest concentration (800 mg/mL) of test extract showed maximum zone of inhibition in all tested standard strains of bacteria (18.3 mm-22 mm). While MIC and MBC values (0.39 mg/mL and 1.56 mg/mL) showed that S. flexneri was the most susceptible pathogen for test extract. CONCLUSION The study revealed that the root extract of B. antidysenterica has antidiarrhoeal and antibacterial activities.

Abstract
The phytochemical investigation of the methanol extract of the stem bark of Gilbertiodendron dewevrei led to the isolation of two new secondary metabolites, 5,7-dihydroxy-4'-methoxyisoflavan-2,4-dione (1) and 23-hydroxy-2-tricosanone (2) along with 19 known compounds (3-21). The structure of these compounds were established by interpretation of their spectral data, mainly HR-TOFESIMS, 1 D NMR (1H, 13C and DEPT) and 2 D NMR (1H-1H COSY, HSQC, HMBC, and NOESY), and by comparison with those reported in the literature. The methanol extract and some isolates were screened for their antiradical, antibacterial, and inhibitory properties against acetylcholinesterase.

Chemotherapeutic Potential of Carthamus Oxycantha Root Extract as Antidiarrheal and In Vitro Antibacterial Activities. Antibiotics (Basel) 2020; 9:antibiotics9050226. [PMID: 32370087 PMCID: PMC7277192 DOI: 10.3390/antibiotics9050226] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2020] [Revised: 04/29/2020] [Accepted: 04/29/2020] [Indexed: 02/07/2023] Open
Abstract
Our research work was designed to investigate the curative and preventive effects of Carthamus oxycantha root extract against diarrhea and microorganisms. For the antibacterial experiment, the agar well diffusion method was used against standard bacteria Staphylococcus aureus, Escherichia coli, Pseudomonas aeroginosa, and Salmonella typhi, while for the assessment of antidiarrheal activity, castor oil and the magnesium sulfate-induced diarrhea method was used on albino, laboratory-bred (BALB/c) mice at a dose rate of 200 and 400 mg/kg (body weight, b.w) orally. The methanol extract of C. oxycantha significantly (p < 0.001) decreased the frequency of defecation, and wet stools in a dose depended on the manner of after receiving magnesium sulfate (2 g/kg (b.w)) and castor oil (1.0 mL/mice). Furthermore, the extract of C. oxycantha showed concentration-dependent antimicrobial properties against S. aureus followed by S. typhi, E. coli, and P. aeroginosa bacterial strains, with inhibitions ranging from 10.5–15 mm. These findings show significant results that C. oxycantha is effective as an antidiarrheal and antibacterial agent. However, further works are needed to establish its mode of action.

Evaluation of the Antidiarrheal Activity of Hydromethanol Crude Extracts of Ruta chalepensis and Vernonia amygdalina in Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:8318713. [PMID: 32351606 PMCID: PMC7174968 DOI: 10.1155/2020/8318713] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Revised: 02/25/2020] [Accepted: 03/20/2020] [Indexed: 11/18/2022]
Abstract
Background The herbal medicine practitioners in Ethiopia have used a wide range of medicinal plants as antidiarrheal agents. Among these, Ruta chalepensis and Vernonia amygdalina were claimed to have antidiarrheal activity in Ethiopian folklore medicine. Hence, the aim of the present study was to evaluate the antidiarrheal activity of the crude extracts of Ruta chalepensis and Vernonia amygdalina in mice. Methods The crude extracts were obtained by cold maceration with 80% methanol, and its antidiarrheal activities were evaluated using a castor oil-induced diarrheal model. The test groups were treated with 100, 200, and 400 mg/kg body weight (bw) of the crude extract of each plant, while the positive controls and negative controls were given loperamide (3 mg/kg.bw) and 2% Tween 80 (10 ml/kg.bw), respectively. Results In the castor oil-induced model, the crude extract of Ruta chalepensis (200 and 400 mg/kg.bw) significantly prolonged the onset of diarrhea in mice. Besides, it also showed a significant reduction in the frequency of stooling and weight of feces. Contrastingly, the crude extract of Vernonia amygdalina had a significant effect in delaying the onset of time of diarrhea and reduction of the frequency of stool and the weight of feces only at the maximum tested dose (400 mg/kg.bw). Conclusion The present study demonstrated that the crude leaves extract of Ruta chalepensis (200 and 400 mg/kg.bw) and Vernonia amygdalina (400 mg/kg.bw) possessed significant antidiarrheal activity in the castor oil-induced diarrheal model.

Ong HG, Kim YD. Medicinal plants for gastrointestinal diseases among the Kuki-Chin ethnolinguistic groups across Bangladesh, India, and Myanmar: A comparative and network analysis study. JOURNAL OF ETHNOPHARMACOLOGY 2020; 251:112415. [PMID: 31917280 DOI: 10.1016/j.jep.2019.112415] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Revised: 11/10/2019] [Accepted: 11/17/2019] [Indexed: 05/20/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Kuki-Chin is a composite ethnolinguistic group made up of many distinct groups and subgroups that are linked by a common history, culture, and population distribution in the Kuki-Chin region, shared geopolitically by Bangladesh, India, and Myanmar. This region is shown to be in a hotspot of digestive disease activity based on official reports and in concordance with data from related ethnopharmacological field surveys. Our work provides a comparative analysis of medicinal plant knowledge for the treatment of gastrointestinal diseases (GAS-Ds) among the Kuki-Chin ethnic groups found across the three countries. AIM OF THE STUDY The objectives were (1) to identify the medicinal plants and herbal therapies for the treatment of GAS-Ds reported in related Kuki-Chin ethnobotanical publications, (2) to find the similarities and differences in medicinal plant knowledge among the country-affiliated groups by comparing plant and disease information, and (3) to determine significant plant taxa and their pattern(s) of use as digestive disease herbal remedies by analyzing disease-plant networks. MATERIALS AND METHODS Secondary data were gathered from 34 related studies through internet search of ethnobotanical information from field studies published in journals, reports, books, and dissertations/theses. These data represented 22 Kuki-Chin ethnolinguistic groups inhabiting 23 districts across six states comprising the Kuki-Chin region: the Chittagong Division (Bangladesh); Mizoram, Assam, Manipur, and Tripura States (India); and Chin State (Myanmar). Scientific names of plants and digestive diseases collated from secondary sources were validated and standardized following the Plant List and the International Classification of Primary Care Second Edition, respectively. RESULTS AND DISCUSSION A total of 482 species in 330 genera and 118 families of vascular plants were recorded for the treatment of 29 standardized GAS-Ds. On the basis of the number of use-reports, regional native species Phyllanthus emblica, Centella asiatica, and Aegle marmelos, as well as the non-natives Carica papaya, Portulaca oleracea, and Psidium guajava were found to be the most preferred. Comparative analysis of medicinal species showed that groups in India revealed the highest number of medicinal plant taxa, followed by those in Bangladesh and Myanmar. The most prevalent GAS-Ds were shown to be abdominal pain epigastric, gastroenteritis presumed infections, and diarrhoea, as supported by the number of use-reports and medicinal taxa used for their treatment, and their informant consensus factor values. Analyses of disease-plant networks graphically showed both GAS-Ds distribution patterns in the region and potential medicinal plant (group) candidates for further studies. CONCLUSION Overall, this study revealed an astonishingly rich diversity of medicinal plants used to treat digestive diseases among the Kuki-Chin. A comparative analysis showed variations and remarkable distinctions in medicinal plant knowledge among country-affiliated groups, as likely influenced by external sociocultural factors and geopolitical barriers, as well as the availability of ethnobotanical data. The use of network analysis reflected not only shared common affinities and patterns of plant use based on the taxonomic composition and species selection, but also disease prevalence and distribution patterns. The information found here can hopefully spur interest among future researchers and policy makers to better improve both the (ethno) medicinal research capacity and healthcare system in the region.

Phytochemical Profiles and Antioxidant Activity of Grasses Used in South African Traditional Medicine. PLANTS 2020; 9:plants9030371. [PMID: 32192145 PMCID: PMC7154885 DOI: 10.3390/plants9030371] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Revised: 02/21/2020] [Accepted: 03/02/2020] [Indexed: 11/29/2022]
Abstract
Grasses are a valuable group of monocotyledonous plants, used as nourishing foods and as remedies against diseases for both humans and livestock. Phytochemical profiles of 13 medicinal grasses were quantified, using spectrophotometric methods and ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC–MS), while the antioxidant activity was done using DPPH and ferric-reducing-power assays. The phytochemical analysis included the total soluble phenolic content, flavonoids, proanthocyanidins, iridoids and phenolic acids. Among the 13 grasses, the root methanolic extracts of Cymbopogon spp., Cymbopogon nardus and Cenchrus ciliaris contained the highest concentrations of total soluble phenolics (27–31 mg GAE/g DW) and flavonoids (4–13 mg CE/g DW). Condensed tannins and total iridoid content were highest (2.3 mg CCE/g DW and 3.2 mg HE/g DW, respectively) in Cymbopogon nardus. The most common phenolic compounds in the grass species included ρ-coumaric, ferulic, salicylic and vanillic acids. In the DPPH radical scavenging assay, the EC50 values ranged from 0.02 to 0.11 mg/mL for the different grasses. The best EC50 activity (lowest) was exhibited by Cymbopogon nardus roots (0.02 mg/mL) and inflorescences (0.04 mg/mL), Cymbopogon spp. roots (0.04 mg/mL) and Vetiveria zizanioides leaves (0.06 mg/mL). The highest ferric-reducing power was detected in the whole plant extract of Cynodon dactylon (0.085 ± 0.45; r2 = 0.898). The observed antioxidant activity in the various parts of the grasses may be due to their rich pool of phytochemicals. Thus, some of these grasses provide a source of natural antioxidants and phytochemicals that can be explored for their therapeutic purposes.
