Saptarini NM, Kelutur FJ, Corpuz MJAT. Exploring the Antidiarrheal Properties of Papaya Leaf: Insights In Vivo Study in Mice-Model and In Silico Analysis at M3 Muscarinic Acetylcholine Receptor Interaction. SCIENTIFICA 2024; 2024:1558620. [PMID: 38962530 PMCID: PMC11221971 DOI: 10.1155/2024/1558620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 04/23/2024] [Accepted: 05/13/2024] [Indexed: 07/05/2024]
Abstract
Diarrhea caused by gut motility involves 5-HT3 serotonin receptor (5-HT3R) antagonist, M3 muscarinic acetylcholine receptor (M3-AchR), and H1 histamine receptor (H1R) via their respective agonist. Papaya (Carica papaya L.) leaf is an herbal medicine to treat diarrhea in Indonesia, though this has not yet been proven scientifically. This study aimed to determine the antidiarrheal properties of papaya leaf through in vivo and in silico studies. In the mice model, papaya leaves were infused with distilled water and subjected to in vivo antidiarrheal study using castor oil-induced diarrhea. In silico molecular docking study of nineteen secondary metabolites was carried out on the M3-AchR (PDB ID: 5ZHP) using AutoDock Tools 1.5.6, while ADMET was predicted by pre-ADMET. The results showed that papaya leaf infusion caused a decrease in the total number of feces, an increase in the onset time of diarrhea, a reduction in the frequency of diarrhea, and an increase in the percentage of inhibition of diarrhea. Quercetin 3-rutinoside, a flavonoid glycoside, is potentially an antidiarrheal remedy at M3-AchR. ADMET prediction showed good distribution on the target and was not toxic, but absorption needed to be considered. We concluded that the antidiarrheal activity of papaya leaf infusion was dose-dependent. Based on a molecular docking study, the flavonoid glycoside was very effective as an antidiarrheal remedy. ADMET prediction showed a specific distribution to the target and was not toxic.

[PMID: 38803577 PMCID: PMC11129909 DOI: 10.1155/2024/5922487] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 04/26/2024] [Accepted: 04/29/2024] [Indexed: 05/29/2024] Open
Abstract
Diarrhea continues to be one of the top causes of death in children under the age of five, particularly in developing nations. In Ethiopian traditional medicine, a variety of medicinal plants are used to treat diarrhea. One of these plants is Maytenus addat (Loes.) Sebsebe (fam. Celastraceae), which is endemic to the Afromontane forests, especially along forest margins, of Ethiopia. The air-dried powdered leaves of M. addat were macerated with 80% methanol to yield a crude extract. Additionally, the powdered plant material underwent sequential solvent extraction using chloroform, methanol, and water to obtain solvent fractions. The 80% methanol leaf extract, solvent fractions, and an isolated compound from M. addat were evaluated for their antidiarrheal activity using castor oil-induced diarrheal model, anti-enteropooling test, and charcoal meal test in mice. The results showed that the 80% methanolic leaf extract significantly reduced the onset of diarrhea, the weight of feces, and the frequency of defecation in all the tested doses. The methanol and water fractions of the hydroalcoholic extract also exhibited dose-dependent antidiarrheal activity, with the methanol fraction showing the highest activity at 400 mg/kg dose. Subsequently, the most active methanol fraction was subjected to C-18 solid phase extraction, resulting in the isolation of a 3-hydroxyflavone, identified as quercetin by ESI-qToF-MS, 1H, and 13C-NMR spectroscopic techniques. Quercetin demonstrated a strong antidiarrheal activity in a dose-dependent manner. Thus, the present study provided evidence that the leaves of M. addat possess genuine antidiarrheal activity upholding the traditional medicinal use of the plant for the treatment of diarrhea. The findings also suggest that quercetin is responsible, in full or in part, for the activity of the plant.

In Vitro Assessment of Myorelaxant and Antispasmodic Effects of Stigmas, Tepals, and Leaves Hydroethanolic Extracts of Crocus sativus. J Food Biochem 2023.

Abstract
The valorization of Crocus sativus focuses mainly on the plant’s stigma because it is one of the most expensive and valuable spices in the world and has great value in the food, cosmetics, and pharmacological industries. Due to this high stigma value, the other parts of the plant are considered as by-products; our study aimed to evaluate the myorelaxant and antispasmodic activities of the byproducts (tepals and leaves) to compare them with the stigma of the plant. To investigate the myorelaxant and antispasmodic activities of the Crocus sativus on isolated rabbit and rat jejunum, we used an in vitro technic with an organ bath and an isotonic transducer. Our results showed that the STG (hydroethanolic extract of stigmas) and LV (hydroethanolic extract of leaves) had a moderate myorelaxant effect with IC50 = 6.61 ± 1.5 and 5.08 ± 0.45 mg/ml, respectively. TPL (hydroethanolic extract of tepals) had a significant (
) inhibitory effect on the amplitude of the rabbit jejunum basic contractions with an IC50 = 1.36 ± 0.15 mg/ml. TPL also caused a significant (
) antispasmodic activity depending on the dose of the contraction induced by CCh (10−6 M) and KCl (25 mM). The antispasmodic effect of the TPL is slightly altered in the presence of nifedipine by a percentage of 26.8%. This difference is statistically significant (
). Therefore, the extract could induce the inhibitory effect on L-type voltage-dependent Ca2+ channels, but not on the guanylate cyclase and nitric oxide pathways. That confirmed that the TPL has a comparable effect to the verapamil. The HPLC-DAD analysis of various parts of C. sativus shows that the three extracts contain the kaempferol flavanol compound, the STG also was revealed to be rich in carotenoids crocin, and these isomers are trans and cis-crocin, safranal, and picrocrocin. In contrast, the TPL revealed the presence of isorhamnetin and quercetin, but the LV was rich in hesperidin and mangiferin. In conclusion, this study supports the traditional use of this plant to treat digestive problems and will allow us to explore future possibilities for treating bowel spasms using natural molecules derived from saffron.

Abstract
Introduction: Quercus L. genus (Oak) belongs to the family Fagaceae and their galls are used commercially in leather tanning, dyeing, and ink preparation. Several Quercus species were traditionally used to manage wound healing, acute diarrhea, hemorrhoid, and inflammatory diseases. The present study aims to investigate the phenolic content of the 80% aqueous methanol extract (AME) of Q. coccinea and Q. robur leaves as well as to assess their anti-diarrheal activity. Methods: Polyphenolic content of Q. coccinea and Q. robur AME were investigated using UHPLC/MS. The antidiarrheal potential of the obtained extracts was evaluated by conducting a castor oil-induced diarrhea in-vivo model. Result and Discussion: Twenty-five and twenty-six polyphenolic compounds were tentatively identified in Q. coccinea and Q. robur AME, respectively. The identified compounds are related to quercetin, kaempferol, isorhamnetin, and apigenin glycosides and their aglycones. In addition, hydrolyzable tannins, phenolic acid, phenyl propanoides derivatives, and cucurbitacin F were also identified in both species AME of Q. coccinea (250, 500, and 1000 mg/kg) exhibited a significant prolongation in the onset of diarrhea by 17.7 %, 42.6%, and 79.7% respectively while AME of Q. robur at the same doses significantly prolonged the onset of diarrhea by 38.6%, 77.3%, and 2.4 folds respectively as compared to the control. Moreover, the percentage of diarrheal inhibition of Q. coccinea was 23.8%, 28.57%, and 42,86% respectively, and for Q. robur 33.34%, 47.3%, and 57.14% respectively as compared to the control group. Both extracts significantly decreased the volume of intestinal fluid by 27%, 39.78%, and 50.1% for Q. coccinea respectively; and by 38.71%, 51.19%, and 60% for Q. robur respectively as compared to the control group. In addition, AME of Q. coccinea exhibited a peristaltic index of 53.48, 47.18, and 42.28 with significant inhibition of gastrointestinal transit by 18.98%, 28.53%, and 35.95 % respectively; while AME of Q. robur exhibited a peristaltic index of 47.71, 37, and 26.41 with significant inhibition of gastrointestinal transit by 27.72%, 43.89%, and 59.99% respectively as compared with the control group. Notably, Q. robur showed a better antidiarrheal effect in comparison with Q. coccinea and, the highest effect was observed for Q. robur at 1000 mg/kg as it was nonsignificant from the loperamide standard group in all measured parameters.

Abstract
Cassava (Manihot esculenta Crantz) is considered one of the essential tuber crops, serving as a dietary staple food for various populations. This systematic review provides a comprehensive summary of the nutritional and therapeutic properties of cassava, which is an important dietary staple and traditional medicine. The review aims to evaluate and summarize the phytochemical components of cassava and their association with pharmacological activities, traditional uses, and nutritional importance in global food crises. To collect all relevant information, electronic databases; Cochrane Library, PubMed, Scopus, Web of Science, Google Scholar, and Preprint Platforms were searched for studies on cassava from inception until October 2022. A total of 1582 studies were screened, while only 34 were included in this review. The results of the review indicate that cassava has diverse pharmacological activities, including anti-bacterial, anti-cancer, anti-diabetic, anti-diarrheal, anti-inflammatory, hypocholesterolemic effects, and wound healing properties. However, more studies that aim to isolate the phytochemicals in cassava extracts and evaluate their pharmacological property are necessary to further validate their medical and nutritional values.

Abstract
The present study was conducted to investigate the protective action of Salvia officinalis flowers aqueous extract (SOFAE) against combined gastro-intestinal (GI) disorders-induced by ethanol and castor oil administration in rats. Adult male Wistar rats were divided into seven groups of ten each and various doses of SOFAE (50, 100, and 200 mg kg−1, b.w., p.o.) and sulfasalazine (100 mg kg−1, b.w., p.o.) were daily administrated during 15 days. After, animals were intoxicated with a single oral administration of ethanol (4 g kg−1, b.w., p. o.) and castor oil (5 mL kg−1, b.w., p.o.). We found that SOFAE contains several phytoactive compounds with a strong ABTS scavenging ability. In vivo, we showed that SOFAE protected against EtOH/CO-induced macroscopic and histological alterations in GI tract accompanied by intestinal fluid accumulation and gastric juice decrease. SOFAE significantly counteracted lipoperoxydation increase and reversed the depletion of both enzymatic and non-enzymatic antioxidants. More importantly, SOFAE significantly reduced the levels of inflammatory markers (CRP and ALP) in plasma and mucosal GI tract. In conclusion, our data clearly indicate that the SOFAE exerted a potential protective effect against EtOH-induced peptic ulcer combined with CO-induced diarrhea in rats. These effects could be associated with its antioxidant and anti-inflammatory properties.

Abstract
Monterey cypress (Cupressus macrocarpa) is a decorative plant; however, it possesses various pharmacological activities. Therefore, we explored the phytochemical profile of C. macrocarpa root methanol extract (CRME) for the first time. Moreover, we investigated its antidiarrheal (in vivo), antibacterial, and antibiofilm (in vitro) activities against Salmonella enterica clinical isolates. The LC-ESI-MS/MS analysis of CRME detected the presence of 39 compounds, besides isolation of 2,3,2″,3″-tetrahydro-4'-O-methyl amentoflavone, amentoflavone, and dihydrokaempferol-3-O-α-l-rhamnoside for the first time. Dihydrokaempferol-3-O-α-l-rhamnoside presented the highest antimicrobial activity and the range of values of MICs against S. enterica isolates was from 64 to 256 µg/mL. The antidiarrheal activity of CRME was investigated by induction of diarrhea using castor oil, and exhibited a significant reduction in diarrhea and defecation frequency at all doses, enteropooling (at 400 mg/kg), and gastrointestinal motility (at 200, 400 mg/kg) in mice. The antidiarrheal index of CRME increased in a dose-dependent manner. The effect of CRME on various membrane characters of S. enterica was studied after typing the isolates by ERIC-PCR. Its impact on efflux and its antibiofilm activity were inspected. The biofilm morphology was observed using light and scanning electron microscopes. The effect on efflux activity and biofilm formation was further elucidated using qRT-PCR. A significant increase in inner and outer membrane permeability and a significant decrease in integrity and depolarization (using flow cytometry) were detected with variable percentages. Furthermore, a significant reduction in efflux and biofilm formation was observed. Therefore, CRME could be a promising source for treatment of gastrointestinal tract diseases.

Abstract
BACKGROUND Diarrhea is a multifactorial gastrointestinal disorder responsible for about 5 million deaths annually. The chemical composition, the antioxidant activity of Crataegus azarolus berries aqueous extract (CABAE) as well as its protective effects against castor oil-induced diarrhea, oxidative stress, and inflammation in rat were studied. METHODS Sixty male rats were used and divided into six groups of ten animals in each: Control (C), castor oil (CO), CO+various doses of CABAE (100, 200, and 400 mg/kg b.w., p.o.), and CO+loperamide (LOP, 10 mg/kg b.w., p.o.). KEY RESULTS The CABAE showed relatively high levels of total polyphenols, flavonoids, and tannins. The LC-HRESIMS technique allowed the identification of 5 phenolic compounds and the major component is quinic acid. In vivo studies showed that CABAE protected against castor oil-induced diarrhea and intestinal fluid accumulation. The CABAE counteracted castor oil-induced lipoperoxidation, preserved GSH and thiol groups levels, and prevented the depletion of antioxidant enzyme activities, such as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). The CABAE administration also protected against castor oil-induced inflammatory markers (ALP and CRP) increase. More importantly, castor oil induced an increase of intracellular mediators, such as hydrogen peroxide, free iron, and calcium, while CABAE pretreatment significantly reversed them to near control levels. CONCLUSION The Crataegus azarolus berries aqueous extract significantly protected against diarrhea due in part to its antioxidant and anti-inflammatory properties.

Abstract
The angiotensin (Ang) II converting enzyme (ACE II) pathway has recently been shown to be associated with several beneficial effects on the body, especially on the cardiac system and gastrointestinal tract. ACE II is responsible for converting Ang II into the active peptide Ang-(1-7), which in turn binds to a metabotropic receptor, the Mas receptor (MasR). Recent studies have demonstrated that Diminazene Aceturate (DIZE), a trypanosomicide used in animals, activates the ACE II pathway. In this study, we aimed to evaluate the antidiarrheal effects promoted by the administration of DIZE to activate the ACE II/Ang-(1-7)/MasR axis in induced diarrhea mice models. The results show that activation of the ACE II pathway exerts antidiarrheal effects that reduce total diarrheal stools and enteropooling. In addition, it increases Na+/K+-ATPase activity and reduces gastrointestinal transit and thus inhibits contractions of intestinal smooth muscle; decreases transepithelial electrical resistance, epithelial permeability, PGE2-induced diarrhea, and proinflammatory cytokines; and increases anti-inflammatory cytokines. Enzyme-linked immunosorbent assay (ELISA) demonstrated that DIZE, when activating the ACE II/Ang-(1-7)/MasR axis, can still interact with GM1 receptors, which reduces cholera toxin-induced diarrhea. Therefore, activation of the ACE II/Ang-(1-7)/MasR axis can be an important pharmacological target for the treatment of diarrheal diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Argentine traditional medicine it is recorded the use of Jodina rhombifolia (Hook. & Arn.) Reissek (Santalaceae) leaves for treating various affections that compromise the intestinal normal functioning. AIM OF THE STUDY The aim of this study was to assess the effect of J. rhombifolia leaves lyophilized aqueous extract on the intestinal function by means of in vivo and ex vivo experimental assays for determinate the antidiarrheal and antispasmodic capacity. Furthermore, was to evaluate its acute toxicity potential by oral and intraperitoneal administration of extract. MATERIALS AND METHODS The in vivo assays were conducted by the experimental techniques of intestinal transit in mice, intestinal fluid accumulation in rats and Castor oil-induced diarrhea in mice. In the ex vivo assays, isolated rat duodenum and ileum segments were used for to evaluate the antispasmodic activity through contractile concentration-response curves induced by Carbachol and CaCl2. The acute toxicity of the extract was also investigated by oral and intraperitoneal administration. RESULTS The extract intraperitoneal administration at the doses 125, 250 and 500 mg/kg, caused a marked reduction in the normal intestinal transit and in the number of diarrheal episodes in a dose-dependent manner. However, the extract did not produce significant changes in the intestinal fluid accumulation with any of the tested dose. The extract demonstrated a non-competitive inhibitory effect on the contractions of intestinal smooth muscle experimentally provoked by the spasmogenic agents Carbachol and CaCl2 in a dose-dependent manner (IC50 = 10.57 ± 1.38 and 6.29 ± 1.54 mg extract/ml Tyrode solution in the isolated organ bath, respectively). ANOVA indicated a significative effect of treatment (p < 0.001). CONCLUSIONS The scientific evidence achieved based in the used experimental models allows us to indicate that J. rhombifolia leaves lyophilized aqueous extract manifest an antispasmodic activity on intestinal smooth muscle without observation of apparent toxicity symptoms.

Evaluation of Various Solvent Extracts of Tetrastigma leucostaphylum (Dennst.) Alston Leaves, a Bangladeshi Traditional Medicine Used for the Treatment of Diarrhea. Molecules 2020; 25:molecules25214994. [PMID: 33126608 PMCID: PMC7662597 DOI: 10.3390/molecules25214994] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 10/24/2020] [Accepted: 10/26/2020] [Indexed: 12/23/2022] Open
Abstract
Tetrastigma leucostaphylum (TL) is an important ethnic medicine of Bangladesh used to treat diarrhea and dysentery. Hence, current study has been designed to characterize the antidiarrheal (in vivo) and cytotoxic (in vitro) effects of T. leucostaphylum. A crude extract was prepared with methanol (MTL) and further partitioned into n-hexane (NTL), dichloromethane (DTL), and n-butanol (BTL) fractions. Antidiarrheal activity was investigated using castor oil induced diarrhea, enteropooling, and gastrointestinal transit models, while cytotoxicity was evaluated using the brine shrimp lethality bioassay. In antidiarrheal experiments, all doses (100, 200, and 400 mg/kg) of the DTL extract significantly reduced diarrheal stool frequency, volume and weight of intestinal contents, and gastrointestinal motility in mice. Similarly, in the cytotoxicity assay, all extracts exhibited activity, with the DTL extract the most potent (LC50 67.23 μg/mL). GC-MS analysis of the DTL extract identified 10 compounds, which showed good binding affinity toward M3 muscarinic acetylcholine, 5-HT3, Gut inhibitory phosphodiesterase, DNA polymerase III subunit alpha, and UDP-N-acetylglucosamine-1 carboxyvinyltransferase enzyme targets upon molecular docking analysis. Although ADME/T analyses predicted the drug-likeness and likely safety upon consumption of these bioactive compounds, significant toxicity concerns are evident due to the presence of the known phytotoxin, 2,4-di-tert-butylphenol. In summary, T. leucostaphylum showed promising activity, helping to rationalize the ethnomedicinal use and importance of this plant, its safety profile following both acute and chronic exposure warrants further investigation.

Individual and synergistic protective properties of Salvia officinalis decoction extract and sulfasalazine against ethanol-induced gastric and small bowel injuries. RSC Adv 2020; 10:35998-36013. [PMID: 35517119 PMCID: PMC9056994 DOI: 10.1039/d0ra03265d] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Accepted: 09/22/2020] [Indexed: 12/12/2022] Open
Abstract
The present study was carried out to determine the phytochemical composition of Salvia officinalis flowers decoction extract (SOFDE) as well as its individual and/or synergistic actions with sulfasalazine against ethanol (EtOH)-induced peptic ulcer in Wistar rats. In this respect, rats were divided into six groups of eight animals each: control, EtOH, EtOH + sulfasalazine (SULF, 100 mg kg-1, b.w., p.o.), mixture: MIX (SOFDE, 50 mg kg-1 b.w., p.o. + SULF, 50 mg kg-1, b.w., p.o.) and EtOH + two doses of SOFDE (100 and 200 mg kg-1 b.w., p.o.). In vitro, the phytochemical and the antioxidant properties were determined using colorimetric analysis. HPLC-PDA/ESI-MS assay was used to identify the distinctive qualitative profile of phenolic compounds. Our results firstly indicated that SOFDE is rich in total tannins, flavonols, anthocyanins and a moderate concentration of total carotenoids. Chromatographic techniques allowed the identification of 13 phenolic compounds and the major ones are quinic acid, protocatechuic acid, gallic acid and salviolinic acid. SOFDE also exhibited an important in vitro antioxidant activity using the β-carotene bleaching method. In vivo, SOFDE and the mixture provide significant protection against ethanol-induced gastric and duodenal macroscopic and histological alterations. Also, SOFDE alone or in combination with SULF, showed a significant protection against the secretory profile disturbances, lipid peroxidation, antioxidant enzyme activities and non-enzymatic antioxidant level depletion induced by alcohol administration. Importantly, we showed that EtOH acute intoxication increased gastric and intestinal calcium, free iron, magnesium and hydrogen peroxide (H2O2) levels, while SOFDE/MIX treatment protected against all these intracellular mediators' deregulation. We also showed that alcohol treatment significantly increased the C-reactive protein (CRP) and alkaline phosphatase (ALP) activities in plasma. The SOFDE and MIX treatment significantly protected against alcohol-induced inflammation. More importantly, we showed in the present work that the mixture exerted a more important effect than SOFDE and SULF each alone indicating a possible synergism between these two molecules. In conclusion, our data suggests that SOFDE and SULF exerted a potential synergistic protective effect against all the macroscopic, histological and biochemical disturbances induced by EtOH intoxication. This protection might be related in part to its antioxidant and anti-inflammatory properties as well as by negatively regulating Fenton reaction components such as H2O2 and free iron.

Antidiarrheal activity of farnesol in rodents: Pharmacological actions and molecular docking. Eur J Pharmacol 2020; 874:172986.

Abstract
Diarrhea is a condition in which the individual has about three or more daily bowel movements, followed by changes in stool consistency. It is currently considered as one of the worst public health problems due to the number of cases and deaths involved and difficulty of treatment. Thus, the use of natural products is an alternative for new treatments. Among these possibilities is Farnesol (C15H26O), a sesquiterpene found in different herbal species that has known biological activities. The objective of this study was to evaluate the antidiarrheal activity of Farnesol (FOH). Initially, FOH activity was evaluated in models of diarrhea and enteropooling induced by castor oil and PGE2. To evaluate motility, the opioid and cholinergic pathways were studied. In addition, the effect of FOH was investigated in the secretion model in intestinal loops treated with cholera toxin. FOH was evaluated for the ability to absorb fluids in intestinal loops and interact with GM1 receptors using the ELISA method and molecular docking. The dose of 50 mg/kg of FOH showed the best results in all antidiarrheal activity tests with castor oil and PGE2, being considered as the standard dose, reducing motility by anticholinergic mechanisms. There was a reduction in fluid secretion when FOH interacted directly with GM1 receptors; cholera toxin and molecular docking showed strong interaction between farnesol and these targets. In view of the results presented, the antidiarrheal activity occurs through anticholinergic, anti-inflammatory and anti-secretory action, making farnesol a potential candidate for the development of a new drug to treat diarrheal diseases.

Abstract
Anadenanthera colubrina var. cebil (Griseb.) Altschul (Fabaceae family), commonly known as the red angico tree, is a medicinal plant found throughout Brazil’s semi-arid area. In this study, a chemical analysis was performed to investigate the antidiarrheal activity and safety profile of red angico gum (RAG), a biopolymer extracted from the trunk exudate of A. colubrina. Upon FT-IR spectroscopy, RAG showed bands in the regions of 1608 cm−1, 1368 cm−1, and 1029 cm−1, which relate to the vibration of O–H water molecules, deformation vibration of C-O bands, and vibration of the polysaccharide C-O band, respectively, all of which are relevant to glycosidic bonds. The peak molar mass of RAG was 1.89 × 105 g/mol, with the zeta potential indicating electronegativity. RAG demonstrated high yield and solubility with a low degree of impurity. Pre-treatment with RAG reduced the total diarrheal stool and enteropooling. RAG also enhanced Na+/K+-ATPase activity and reduced gastrointestinal transit, and thereby inhibited intestinal smooth muscle contractions. Enzyme-Linked Immunosorbent Assay (ELISA) demonstrated that RAG can interact with GM1 receptors and can also reduce E. coli-induced diarrhea in vivo. Moreover, RAG did not induce any signs of toxicity in mice. These results suggest that RAG is a possible candidate for the treatment of diarrheal diseases.

Abstract
Background:
Peptic ulcer is a deep gastrointestinal erosion disorder that involves
the entire mucosal thickness and can even penetrate the muscular mucosa. Nowadays, several
plants and compounds derived from it have been screened for their antiulcer activity. In
the last few years, there has been an exponential growth in the field of herbal medicine. This
field has gained popularity in both developing and developed countries because of their natural
origin and less side effects.
Objective:
This review aims to provide a comprehensive summary of currently available
knowledge of medicinal plants and phytoconstituents reported for their anti-ulcer properties.
Methods:
The worldwide accepted database like SCOPUS, PUBMED, SCIELO, NISCAIR,
ScienceDirect, Springerlink, Web of Science, Wiley, SciFinder and Google Scholar were
used to retrieve available published literature.
Results:
A comprehensive review of the present paper is an attempt to list the plants with
antiulcer activity. The review narrates the dire need to explore potential chemical moieties
that exert an antiulcer effect, from unexploited traditional plants. Furthermore, the present
study reveals the intense requirement to exploit the exact mechanism through which either
the plant extracts or their active constituents exhibit their antiulcer properties.
Conclusion:
This article is the compilation of the plants and its constituents reported for the
treatment of peptic ulcers. The Comprehensive data will surely attract the number of investigators
to initiate further research that might lead to the drugs for the treatment of ulcers. As
sufficient scientific data is not available on plants, most of the herbals cannot be recommended
for the treatment of diseases. This can be achieved by research on pure chemical
structures derived from plants or to prepare new lead compounds with proven beneficial
preclinical in vitro and in vivo effects. However, a lot remains to be done in further investigations
for the better status of medicinal plants.

Nigusse T, Zhang L, Wang R, Wang XN, Li J, Liu C. Flavonoids in a crude extract of Catha edulis inhibit rat intestinal contraction via blocking Ca 2+ channels. Neurogastroenterol Motil 2019; 31:e13602. [PMID: 31012198 DOI: 10.1111/nmo.13602] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Revised: 03/29/2019] [Accepted: 04/01/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND Animal studies show that Catha edulis inhibits gastrointestinal tract motility. However, there is little or no information on its effect on colon motility and the mechanism of action and active constituents responsible for this effect. This study therefore attempted to discern the effect, suggest the mechanism, and identify the active compounds from the crude extract. METHODS A crude extract of Catha edulis was fractionated and subfractionated using column chromatography and HPLC. The activity of all fractions and subfractions was evaluated on rat colon longitudinal muscle. Nuclear magnetic resonance (NMR) spectroscopic data elucidations were used to identify the active compounds. An ileal segment preparation was used to investigate the possible mechanism of action. RESULTS The crude extract of Catha edulis (0.05-0.5 mg/mL) inhibited spontaneous contraction of rat colon and ileum (P < 0.05), and tetrodotoxin (TTX, 10 µmol/L) failed to block this effect. Similar to verapamil (0.01-0.1 μmol/L), the Catha edulis extract (0.05-0.5 mg/mL) inhibited high K+ (80 mmol/L)-induced sustained ileal contraction and decreased the response to Ca2+ . Analysis of the NMR data showed that quercetin, kaempferol, and myricetin were the active phytochemicals. All the identified compounds were flavonoids and significantly inhibited (P < 0.05) spontaneous contraction of the rat colon longitudinal muscle compared to controls. CONCLUSIONS The crude extract of Catha edulis has a spasmolytic effect on the rat ileum, which is mediated through blocking Ca2+ channels, and quercetin, kaempferol, and myricetin were found to be the causative compounds.

Investigation of the Biological Activities and Characterization of Bioactive Constituents of Ophiorrhiza rugosa var. prostrata (D.Don) & Mondal Leaves through In Vivo, In Vitro, and In Silico Approaches. Molecules 2019; 24:molecules24071367. [PMID: 30965575 PMCID: PMC6480688 DOI: 10.3390/molecules24071367] [Citation(s) in RCA: 64] [Impact Index Per Article: 12.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Revised: 03/29/2019] [Accepted: 04/04/2019] [Indexed: 11/17/2022] Open
Abstract
Ophiorrhiza rugosa var. prostrata is one of the most frequently used ethnomedicinal plants by the indigenous communities of Bangladesh. This study was designed to investigate the antidiarrheal, anti-inflammatory, anthelmintic and antibacterial activities of the ethanol extract of O. rugosa leaves (EEOR). The leaves were extracted with ethanol and subjected to in vivo antidiarrheal screening using the castor oil-induced diarrhea, enteropooling, and gastrointestinal transit models. Anti-inflammatory efficacy was evaluated using the histamine-induced paw edema test. In parallel, in vitro anthelmintic and antibacterial activities were evaluated using the aquatic worm and disc diffusion assays respectively. In all three diarrheal models, EEOR (100, 200 and 400 mg/kg) showed obvious inhibition of diarrheal stool frequency, reduction of the volume and weight of the intestinal contents, and significant inhibition of intestinal motility. Also, EEOR manifested dose-dependent anti-inflammatory activity. Anthelmintic action was deemed significant (P < 0.001) with respect to the onset of paralysis and helminth death. EEOR also resulted in strong zones of inhibition when tested against both Gram-positive and Gram-negative bacteria. GC-MS analysis identified 30 compounds within EEOR, and of these, 13 compounds documented as bioactive showed good binding affinities to M3 muscarinic acetylcholine, 5-HT3, tubulin and GlcN-6-P synthase protein targets in molecular docking experiments. Additionally, ADME/T and PASS analyses revealed their drug-likeness, likely safety upon consumption and possible pharmacological activities. In conclusion, our findings scientifically support the ethnomedicinal use and value of this plant, which may provide a potential source for future development of medicines.

Abstract
Diarrhea is one of the leading causes of infant death in the world accounting for high child mortality rate. It is also present in different pathophysiologies related to several etiological agents. The aim of this study is to investigate the antidiarrheal effect of α -Terpineol (α-TPN) in different diarrhea models in rodents. The antidiarrheal effect of α-TPN in the treatment of acute diarrhea and enteropooling induced by castor oil or PGE2 in Swiss mice pretreated orally with saline (NaCl 0.9%), Loperamide (5 mg/kg) and α-TPN (6.25, 12.5, 25 and 50 mg/kg) was analyzed. Additionally, parameters of severity, total weight of faeces and post-treatment for 4 h were evaluated. Modulation of the opioid and cholinergic pathways was performed and intestinal transit model using activated charcoal as marker was also used. The effect of α-TPN on secretory diarrhea was investigated using the model of fluid secretion in intestinal loops isolated from cholera toxin-treated mice. α-TPN showed antidiarrheal effect (*p < 0.05), reducing the total stool amount (*55%, *48%, *44%, *24%) and diarrheal (*47%, *66%; *56%, 10%) respectively for the doses tested. All doses investigated in the enteropooling test presented significant changes (*46%, *78%, *66%, *41% respectively) in relation to the control. α-TPN through the muscarinic pathway reduced the gastrointestinal transit (*31%), besides inhibiting PGE2-induced diarrhea (*39%). α-TPN also reduced fluid formation and loss of Cl- ions, by interacting directly with GM1 receptors and cholera toxin, thus increasing the uptake of intestinal fluids. The results suggest an anti-diarrheal activity of α-TPN due to its anticholinergic action, ability to block PGE2 and GM1 receptors and interaction with cholera toxin in secretory diarrhea, making it a promising candidate drug for the treatment of diarrheal diseases.

Antidiarrheal activity of a novel sulfated polysaccharide from the red seaweed Gracilaria cervicornis. JOURNAL OF ETHNOPHARMACOLOGY 2018; 224:27-35. [PMID: 29803569 DOI: 10.1016/j.jep.2018.05.033] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2017] [Accepted: 05/23/2018] [Indexed: 06/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The use of marine seaweeds as a source of natural compounds with medicinal purposes is increasing in Western countries in the last decades, becoming an important alternative in the traditional medicine of many developing countries, where diarrhea still remains a severe public health problem, with high rates of mortality and morbidity. Sulfated polysaccharides (PLS) extracted from red seaweeds can exhibit therapeutic effects for the treatment of gastrointestinal disorders. Thus, the pharmacological properties of the PLS from Gracilaria cervicornis, an endemic seaweed found in the Brazilian northeast coast, was evaluated as an alternative natural medication for diarrhea. AIM OF THE STUDY This study aimed to evaluate the antidiarrheal activity of sulfated polysaccharides (PLS) extracted from the red seaweed G. cervicornis in Swiss mice pre-treated with castor oil or cholera toxin. MATERIALS AND METHODS The seaweed Gracilaria cervicornis was collected at Flecheiras beach (city of Trairí, State of Ceará, Brazil) and the PLS was obtained through enzymatic extraction and administered in mice (25-30 g) before diarrhea induction with castor oil or cholera toxin. For the evaluation of the total number of fecal output and diarrheal feces, the animals were placed in cages lined with adsorbent material. The evaluation of intestinal fluid accumulation (enteropooling) on castor oil-induced diarrhea in mice occurred by dissecting the small intestine and measuring its volume. The determination of Na+/K+-ATPase activity was measured in the small intestine supernatants by colorimetry, using commercial biochemistry kits. The gastrointestinal motility was evaluated utilizing an activated charcoal as a food tracer. The intestinal fluid secretion and chloride ion concentration were evaluated in intestinal closed loops in mice with cholera toxin-induced secretory diarrhea. The binding ability of PLS with GM1 and/or cholera toxin was evaluated by an Enzyme-Linked Immunosorbent Assay (ELISA). RESULTS The G. cervicornis PLS showed antidiarrheal effects in both acute and secretory diarrhea, reducing the total number of fecal output, diarrheic stools, intestinal fluid accumulation, and increasing small intestine Na+/K+-ATPase activity on castor oil-induced diarrhea. However, the PLS did not affect gastrointestinal motility, indicating that this compound has a different action mechanism than loperamide. In secretory diarrhea, the PLS decreased intestinal fluid secretion and small intestine chloride excretion, binding with GM1 and/or cholera toxin and blocking their attachment to the enterocyte cell surface. CONCLUSIONS In conclusion, PLS has a significant antidiarrheal effect in acute and secretory diarrhea. Further investigation is needed towards its use as a natural medicine to treat diarrhea.

Abstract
Due to the shortcomings associated with modern synthetic antidiarrhoeal drugs, it is important to find newer, safer and cheaper antidiarrhoeal agents from natural sources. The study was conducted to evaluate the anti-diarrhoeal activity of the fractions of the stem-bark of Terminalia avicennioides in laboratory animal models. The effect of different concentrations (1.0 × 10−3, 2.0 × 10−3, 4.0 × 10−3 and 8.0 × 10−3 mg/mL) of the aqueous methanol (AMF), ethyl acetate (EAF) and hexane (HXF) fractions of T. avicennioides were tested against spontaneous and acetylcholine-induced contractions of rabbit jejunum as well as on histamine-induced contraction of guinea pig ileum. Similarly, the effects of the AMF on gastro-intestinal transit time, castor oil-induced diarrhoea and castor oil-induced enteropooling were evaluated. The AMF, EAF and HXF at concentrations of 1.0 × 10−3, 2.0 × 10−3, 4.0 × 10−3 and 8.0 × 10−3 mg/mL attenuated the contractile effects of both the spontaneous and acetylcholine-induced contractions of rabbit jejunum and that of histamine-induced contraction of guinea pig ileum in a concentration-dependent manner. The AMF at doses of 200, 300 and 500 mg/kg produced significant (p < 0.05) reductions in gastrointestinal transit time of charcoal and incidence of castor oil-induced diarrhoea in mice relative to the untreated control. Similarly, at doses of 300 and 500 mg/kg, AMF significantly (p < 0.05) reduced the weight and volume of intestinal fluid in the treated mice when compared to the untreated animals. The results of this study showed that the stem-bark of T. avicennioides possesses spasmolytic effect and could be a potential antidiarrhoeal agent. However, detailed pharmacological trials are required to justify the clinical use of the plant for treating diarrhoea.

Abstract
Rosa species, rose hips, are widespread wild plants that have been traditionally used as medicinal compounds for the treatment of a wide variety of diseases. The therapeutic potential of these plants is based on its antioxidant effects caused by or associated with its phytochemical composition, which includes ascorbic acid, phenolic compounds and healthy fatty acids among others. Over the last few years, medicinal interest in rose hips has increased as a consequence of recent research that has studied its potential application as a treatment for several diseases including skin disorders, hepatotoxicity, renal disturbances, diarrhoea, inflammatory disorders, arthritis, diabetes, hyperlipidaemia, obesity and cancer. In this review, the role of different species of Rosa in the prevention of treatment of various disorders related to oxidative stress, is examined, focusing on new therapeutic approaches from a molecular point of view.

Abstract
INTRODUCTION The myrtle (Myrtus communis) belongs to the Myrtaceae family; it is one of the central plants as part of the list of medicinal plants in the Tunisian Pharmacopoeia. Myrtle berry was used for its astringent, tonic, and antiseptic properties, to treat diarrhea, hemorrhoids, and gastrointestinal injury. METHODS Adult male wistar rats were used to evaluate the normal gastro-intestinal transit and gastric emptying as well as castor oil-induced diarrhea, enteropooling tests, and small intestine oxidative stress. The effect of myrtle berries juice (MBJ) (5 and 10ml/kg, bw. p.o.) was after compared to the loperamide and clonidine effects. RESULTS MBJ significantly and dose-dependently inhibited the intestinal motility and gastric emptying. We also found that MBJ administration induced a significant dose-dependent protection against diarrhea and intestinal fluid accumulation. Castor oil-induced intestinal hypersecretion was accompanied by an oxidative stress status in the intestine, which was attenuated by MBJ administration. CONCLUSION We suggest that MBJ had a potent protective effects against castor oil-induced diarrhea in part due, to its antioxidant and antisecretory properties.

Abstract
INTRODUCTION Rhus tripartita (Anacardiacae) is a plant which is traditionally used for the treatment of ulcer and diarrhea in Tunisia. However, the scientific basis for this usage has not been well established. The core aim of the present study is to evaluate the antidiarrheal activity of Rhus tripartita root methanolic extract (RRE). MATERIAL AND METHODS The antidiarrheal activity of RRE oral doses (50, 100, 200 and 300mg/kg) was evaluated using the castor oil-induced diarrhea, the intestinal fluid emptying method and the normal intestinal transit test. The antibacterial activity was tested against four pathogenic bacteria using two methods. The RRE was also phytochemical studied. RESULTS Diarrhea experiments showed a protective effect of the RRE which produced a significant (p<0.05) and dose-dependent reduction of all the diarrhea parameters. It delayed the onset of diarrhea, produced a significant decrease in the frequency of defecation and the diarrhea score severity and decreased the volume of intestinal fluid induced by castor oil as well as the propulsion intestinal transit. The effect of the extract at the highest dose (300mg/kg) was similar to that of loperamide, the standard anti-diarrheal drug (10mg/kg). The anti-bacterial activity test showed that RRE exhibited a great inhibition activity against four pathogenic bacteria strains (Esherichia coli, Salmonella typhimurium, Salmonella argenosa, Staphylococcus aureus). Oral administration of the extract up to 3g/kg did not produce any acute toxicity in rats. The preliminary phytochemical screening of the RRE revealed the presence of flavonoids, tannins, and polyphenols. CONCLUSION Results showed that RRE at 300mg/kg possesses the highest anti-diarrheal activity possibly mediated by the inhibitory effects on gastrointestinal propulsion and intestinal fluid accumulation.

Quercetin Feeding in Newborn Dairy Calves Cannot Compensate Colostrum Deprivation: Study on Metabolic, Antioxidative and Inflammatory Traits. PLoS One 2016; 11:e0146932. [PMID: 26752173 PMCID: PMC4709053 DOI: 10.1371/journal.pone.0146932] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2015] [Accepted: 12/26/2015] [Indexed: 01/07/2023] Open
Abstract
Immaturity of the neonatal immune system is causative for high morbidity in calves and colostrum intake is crucial for acquiring passive immunity. Pathogenesis is promoted by reactive oxygen species accumulating at birth if counter-regulation is inadequate. The flavonol quercetin exerts antioxidative and anti-inflammatory effects that may enhance neonatal health. The aim of this work was to study effects of quercetin feeding on metabolic, antioxidative and inflammatory parameters in neonatal calves to investigate whether quercetin could compensate for insufficient colostrum supply. Twenty-eight newborn calves were assigned to two dietary groups fed colostrum or milk-based formula on day 1 and 2 and milk replacer thereafter. From day 2 onwards, 7 calves per diet group were additionally fed quercetin aglycone (50 mg/(kg body weight × day)). Blood samples were taken repeatedly to measure plasma concentrations of flavonols, glucose, lactate, total protein, albumin, urea, non-esterified fatty acids, triglycerides, cholesterol, insulin, glucagon, cortisol, immunoglobulins, fibrinogen, haptoglobin and serum amyloid A. Trolox equivalent antioxidative capacity, ferric reducing ability of plasma, thiobarbituric acid reactive species and F2-isoprostanes were analyzed to evaluate plasma antioxidative status. Expression of tumor necrosis factor, interleukin-1α, interleukin-1β, serum amyloid A, haptoglobin, fibrinogen, C-reactive protein, catalase, glutathione peroxidase and superoxide dismutase mRNA were measured in liver tissue on day 8. Plasma flavonol concentrations were detectable only after quercetin-feeding without differences between colostrum and formula feeding. Plasma glucose, lactate, total protein, immunoglobulins, triglycerides, cholesterol, trolox equivalent antioxidative capacity and thiobarbituric acid reactive species were higher after colostrum feeding. Body temperature, fecal fluidity and plasma concentrations of cortisol and haptoglobin were higher in formula- than in colostrum-fed groups. Hepatic mRNA expression of tumor necrosis factor was higher after quercetin feeding and expression of C-reactive protein was higher after formula feeding. Data confirm that colostrum improves neonatal health and indicate that quercetin feeding cannot compensate for insufficient colostrum supply.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Caladium bicolor (Araceae) is a horticulture plant also used by some traditional medicine practitioners in the treatment of diarrhoea and other gastrointestinal disorders. This study was conducted to evaluate the antidiarrhoeal activity of the aqueous leaf extract of C. bicolor and its possible mechanisms of action in rodents. MATERIALS AND METHODS Normal and castor oil-induced intestinal transit and castor oil-induced diarrhoea tests were carried out in mice while gastric emptying and enteropooling tests were conducted in rats following the administration of distilled water (10 ml/kg, p.o.), C. bicolor extract (1-50mg/kg, p.o.) and loperamide (5mg/kg, p.o.). The probable mechanisms of action of C. bicolor was investigated following pre-treatment with yohimbine (10mg/kg, s.c.; α2-adrenoceptor antagonist), pilocarpine (1mg/kg, s.c.; non-selective muscarinic receptor agonist), prazosin (1mg/kg, s.c.; α1-adrenoceptor antagonist) and propranolol (1mg/kg, i.p.; non-selective β-adrenoceptor antagonist) 15 min prior to administration of C. bicolor extract (50mg/kg, p.o.). After 30 min of pre-treatment with these drugs, the mice were subjected to the castor oil-induced intestinal transit test. RESULTS C. bicolor extract did not produce significant (p>0.05) effect on normal intestinal transit unlike loperamide which caused significant (p<0.001) inhibition (61.57%). The extract caused significant (p<0.001) dose-dependent inhibition of castor oil-induced intestinal transit with peak effect, 100% inhibition, elicited at the dose of 50mg/kg compared to 86.97% inhibition for loperamide. Yohimbine and pilocarpine most significantly (p<0.001) reversed this effect of the extract. In the castor oil-induced diarrhoea test, the extract (1mg/kg) and loperamide significantly (p<0.05, 0.01) delayed the onset of diarrhoea. For diarrhoea score, the extract (1 and 50mg/kg) inhibited diarrhoea development (47.53% and 43.83% inhibition, respectively) like loperamide (5mg/kg; 54.94%). The in vivo antidiarrhoeal index of the extract at 1 and 50mg/kg was 50.07% and 42.81% respectively compared to 58.15% for loperamide. CONCLUSIONS The results obtained in this study suggest that the aqueous leaf extract of C. bicolor possess antidiarrhoeal activity due to its anti-motility effect possibly via antagonist action on intestinal muscarinic receptors and agonist action on intestinal α2-adrenoceptors. This justifies the use of the extract in traditional medicine for the treatment of diarrhoea.

Abstract
OBJECTIVES The present study was carried out to determine the antidiarrheal effects of myrtle (Myrtus communis L.) berries seeds aqueous extract (MBSAE) from Tunisia as well as the involvement of its antimicrobial and antioxidant properties in such protection. METHODS Adult male wistar rats were used and divided into six groups of ten each: control, Castor oil, Castor oil + Loperamide and Castor oil + various doses of MBSAE. Animals were per orally (p.o.) pre-treated with MBSAE for one hour and intoxicated by castor oil acute oral administration. KEY FINDINGS Our results demonstrated that the MBSAE is rich in total and condensed tannins and exhibited a broad spectrum of antibacterial activity. In vivo, we found that MBSAE administration induced a significant dose-dependent protection against diarrhoea and intestinal fluid accumulation. Castor oil-induced intestinal hypersecretion was accompanied by an oxidative stress status in the intestine. More importantly, we showed that acute diarrhoea was accompanied by an increase in intestinal mucosa hydrogen peroxide (H2 O2 ), calcium and free iron levels while MBSAE pre-treatment reversed all castor oil-induced intracellular mediators disturbances. CONCLUSIONS We suggest that MBSAE had a potent protective effects against castor oil-induced acute diarrhoea due in part to its antioxidant and antimicrobial properties.

Abstract
Scientific proof for flavonoids as a health tool in calf nutrition is inconsistent. We investigated the effects of the most abundant flavonoid, quercetin, and of a green tea extract (GTE) containing various catechins on the metabolic and antioxidative traits in dairy calves to clarify their potential health-promoting effects. Male newborn German Holstein calves (n=7 per group) received either no flavonoid (control group), 10mg of quercetin equivalents as quercetin aglycone or as rutin/kg of body weight (BW) per day, or 10mg/kg of BW per day of a GTE from d 2 to 26 of life. The supplements were provided with the morning and evening feeding. The calves were fed colostrum and milk replacer, and BW, feed intake, and health status were evaluated daily. Blood samples were collected from a jugular vein on d 1, 5, 12, 19, and 26 before the morning feeding to investigate the metabolic and antioxidative status of the calves. The growth performance and health status remained unchanged, but the GTE-fed calves had fewer loose feces than the controls. The plasma concentrations of quercetin changed over time and were higher in the rutin-fed group than in the control group, whereas the catechins were below the detection limit. The plasma Trolox equivalent antioxidative capacity and ferric reducing ability of plasma were measured as markers for plasma antioxidative capacity. The concentrations of Trolox equivalent antioxidative capacity increased, whereas ferric reducing ability of plasma decreased after the first day of life in all the groups. The oxidative stress markers in the plasma were measured as thiobarbituric acid reactive substances and F2-isoprostanes, but these did not indicate treatment or time effects. The plasma concentrations of total protein, albumin, urea, lactate, glucose, and nonesterified fatty acids and of insulin and cortisol varied over time, but no group differences were caused by the flavonoid supplementation. In summary, orally administered quercetin and catechins at the dosages used in the present study resulted in weak effects on health and no effects on the metabolic and antioxidative status of newborn dairy calves.

Antidiarrheal activity of cashew GUM, a complex heteropolysaccharide extracted from exudate of Anacardium occidentale L. in rodents. JOURNAL OF ETHNOPHARMACOLOGY 2015; 174:299-307. [PMID: 26297843 DOI: 10.1016/j.jep.2015.08.020] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/21/2015] [Revised: 07/18/2015] [Accepted: 08/18/2015] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Anacardium occidentale L. (Anacardiaceae) is commonly known as the cashew tree. It is native to tropical America and extracts of the leaves, bark, roots, chestnut net and exudate have been traditionally used in northeast Brazil for the treatment of various diseases. The exudate of the cashew tree (cashew gum) has been exploited by locals since ancient times for multiple applications, including the treatment of diarrheal diseases. AIM OF THE STUDY The primary aim of the present study is to evaluate the antidiarrheal activity of cashew gum (CG), a complex heteropolysaccharide from the exudate of the cashew tree, using various models. MATERIALS AND METHODS The antidiarrheal activity of cashew gum (CG) against acute diarrhea was investigated using the castor oil-induced diarrhea model. The effects of CG on gastrointestinal transit and castor oil- and PGE2- induced enteropooling were also examined in rodents. In addition, the effect of CG against secretory diarrhea was investigated using a model of fluid secretion in cholera toxin-treated intestinal closed loops in live mice. RESULTS Cashew gum (30, 60, and 90 mg/kg, p.o.) showed a significant (P<0.05-0.01) antidiarrheal effect in rats with castor oil-induced diarrhea, inhibiting the total amount of stool and diarrheal stools. The 60 mg/kg dose of CG exhibited excellent antidiarrheal activity and significantly reduced the severity of diarrhea (diarrhea scores) in rats. CG (60 mg/kg) significantly (P<0.05) decreased the volume of castor oil- and PGE2-induced intestinal fluid secretion (enteropooling). In addition, similar to loperamide (standard drug, 5 mg/kg, p.o.), CG treatment reduced the distance traveled by a charcoal meal in the 30-min gastrointestinal transit model by interacting with opioid receptors. In cholera toxin-induced secretory diarrhea, CG (60 mg/kg) significantly inhibited the intestinal fluid secretion and decreased Cl(-) ion loss in the cholera toxin(-)treated isolated loops model of live mice by competitively binding to cholera toxin-GM1 receptors. CONCLUSIONS In conclusion, our results indicate that a complex heteropolysaccharide extracted from the exudate of A. occidentale L. has antidiarrheal activity in acute, inflammatory, and secretory diarrhea models, which could justify its traditional use in the treatment of diarrhea in northeast Brazil. The antidiarrheal activity might be explained by the capacity of CG to inhibit gastrointestinal motility and thereby reduce the accumulation of intestinal fluid and the secretion of water and chloride ions in the lumen of the intestine.

Abstract
BACKGROUND The leaf of Zehneria scabra is traditionally used for the management of diarrhea in Ethiopia. Its use, however, has not been scientifically validated for safety and efficacy. The aim of this study was to investigate antidiarrheal and antisecretory effects of hydroalcolic leaf extract of Z. scabra in mice models. METHODS For each of antidiarrheal, gastrointestinal motility and antisecretory activity study Swiss albino mice were divided in to five groups. Group I was treated as control group and received 10 ml/kg of 2% Tween-80 orally; Group II served as a positive control and took standard drug in each of the experiments orally; Group III, IV and V were test groups which received the methanolic extract orally at 100, 200 and 400 mg/kg, respectively. Depending on the model total weight of fecal output, total weight of wet feces, total number of fecal output, number of wet faeces, length of intestinal transit and intestinal weight were collected. Finally, data were analyzed using one-way ANOVA followed by Tukey's post test. RESULT In castor oil induced diarrhea model, the extract dose produced a significant reduction in mean stool score (1.94 ± 0.102) at 200 mg/kg. Moreover, the 100, 200, and 400 mg/kg doses inhibited stool frequency by 40, 45 and 55%, respectively. All test doses of extract and loperamide (3mg/kg) reduced fecal fluid content significantly (p<0.01). The 100 mg/kg dose of extract produced 25.74% reduction of fluid content (p<0.001) while both 200 and 400 mg/kg showed 29.70 % (p<0.001) compared to negative control group. CONCLUSION The extract of Zehineria scabra showed antidiarrheal and antisecretory activity in mice model. Moreover, the extract found to be safe at dose of 2000mg/kg in mice model. The findings suggest the validity of the acclaimed effect of Zehineria scabra as antidiarrheal agent in Ethiopian traditional herbal medicine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Matricaria recutita L. (Chamomile) has been widely used in the Tunisian traditional medicine for the treatment of digestive system disorders. The present work aims to investigate the protective effects of chamomile decoction extract (CDE) against castor oil-induced diarrhea and oxidative stress in rats. METHODS The antidiarrheal activity was evaluated using castor oil-induced diarrhea method. In this respect, rats were divided into six groups: Control, Castor oil, Castor oil+Loperamide (LOP) and Castor oil+various doses of CDE. Animals were per orally (p.o.) pre-treated with CDE during 1h and intoxicated for 2 or 4h by acute oral administration of castor oil. RESULTS Our results showed that CDE produced a significant dose-dependent protection against castor oil-induced diarrhea and intestinal fluid accumulation. On the other hand, we showed that diarrhea was accompagned by an oxidative stress status assessed by an increase of malondialdehyde (MDA) level and depletion of antioxidant enzyme activities as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx). Castor oil also increased gastric and intestinal mucosa hydrogen peroxide (H2O2) and free iron levels. Importantly, we showed that chamomile pre-treatment abrogated all these biochemical alterations. CONCLUSION These findings suggested that chamomile extract had a potent antidiarrheal and antioxidant properties in rats confirming their use in traditional medicine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pupalia lappacea is a medicinal plant found in savannah and woodland localities and forest path sides from Senegal to Southern Nigeria. It has been used in the management of diarrhoea in Nigerian traditional medicine. This study was designed to evaluate the antidiarrhoeal activity of the hydroethanolic leaf extract of Pupalia lappacea (PL). MATERIALS AND METHODS The antidiarrhoeal activity of PL was evaluated using the normal and castor oil-induced intestinal transit, castor oil-induced diarrhoea, gastric emptying and intestinal fluid accumulation tests in rodents. RESULTS PL (100-400mg/kg, p.o.) produced a significant dose-dependent decrease in normal and castor oil-induced intestinal transit compared with the control group (distilled water 10ml/kg, p.o.). This effect was significantly (P<0.05) inhibited by pilocarpine (1mg/kg, s.c.) but not by yohimbine (10mg/kg, s.c.), prazosin (1mg/kg, s.c.), or propranolol (1mg/kg, i.p.). The extract produced a dose-dependent and significant increase in the onset of diarrhoea. PL (100-400mg/kg) also reduced the diarrhoea score, number and weight of wet stools. The in-vivo antidiarrhoeal index (ADIin vivo) of 56.95% produced by the extract at the dose of 400mg/kg was lower compared to that produced by loperamide 5mg/kg (77.75%). However, PL (400mg/kg) significantly increased gastric emptying in rats but significantly reduced the volume of intestinal content in the intestinal fluid accumulation test. Phytochemical analysis of the extract revealed the presence of alkaloids, saponins, and fixed oils and fats. The acute toxicity studies revealed that the extract is relatively safe when given orally; no death was recorded at a dose of 10g/kg. CONCLUSION Results showed that the hydroethanolic leaf extract of Pupalia lappacea possesses antidiarrhoeal activity possibly mediated by antimuscarinic receptor activity.

Abstract
CONTEXT Ardisia elliptica Thunb Lam. (Myrsinaceae) is widely used traditionally in the treatment of diarrhea related health disorders in Bangladesh. OBJECTIVE The crude ethanol extract of Ardisia elliptica fruits (EFA) was evaluated for its antioxidant and antidiarrhoeal activities. MATERIALS AND METHODS DPPH radical scavenging, nitric oxide scavenging, reducing power and Fe(++) ion chelating ability were used for determining antioxidant activities and animal models were used for antidiarrheal activities such as the castor oil and magnesium sulfate-induced diarrhea, enteropooling induced by the administration of castor oil and magnesium sulfate at the doses of 250 and 500 mg/kg. RESULTS The extract possessed a significant DPPH free radical scavenging activity with an IC50 value of 30.75 μg/ml compared to ascorbic acid (IC50: 7.89 μg/ml). The IC50 values of the extract and ascorbic acid were 51.72 and 38.68 μg/ml, respectively, in nitric oxide scavenging assay. The IC50 value of the extract for Fe(++) ion chelating ability (41.30 μg/ml) was also found to be significant compared to the IC50 value of EDTA (22.57 μg/ml). The EFA also showed a significant protection (p < 0.001) against experimentally induced diarrhea by castor oil and magnesium sulfate as evidenced by a decrease in the number of defecation with respect to control. The diarrhea induced by castor oil and magnesium sulfate enteropooling was prevented by all the tested doses. CONCLUSION Therefore, the obtained results confirm the antioxidant and antidiarrheal activity of EFA and thus support the traditional uses of this plant as a modality for antioxidant and antidiarrheal activity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Flos populi (male inflorescence of Populus tomentosa Carrière) has been traditionally used in East Asian countries for the treatment of various inflammatory diseases, strengthening the spleen and stomach, anti-rheumatic, anti-tumor and anti-diarrhoeal. AIM OF THE STUDY To evaluate the in vivo or in vitro anti-diarrhoeal and anti-microbial activity of Flos populi aqueous extract. MATERIALS AND METHODS Acute toxicity of Flos populi aqueous extract (FPAE) was investigated. Castor oil-induced diarrhoea method was used to evaluate the anti-diarrhoeal activity, inhibition of defecation and diarrhoea were determined in mice, effects on castor oil-induced enteropooling, intestinal transit and intestinal fluid secretion in rats or mice. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of FPAE against strains of three clinical bacterial isolates and one reference strain were used to test the anti-microbial activity. RESULTS The FPAE reduced the frequency of diarrhoea episodes and decreased the propulsion of charcoal meal through the gastrointestinal tract in a dose dependent manner. FPAE (100-500 mg/kg, p.o.) produced dose-dependent and significant (P<0.01) protection of mice against castor oil-induced diarrhoea. FPAE, dose-dependently and significantly (P< 0.01) delayed the onset of castor-oil induced diarrhoea, decreased the frequency of defecation, and reduced the severity of diarrhoea. Compared with control animals, FPAE, dose-dependently and significantly (P< 0.01) decreased the volume of castor oil-induced intestinal fluid secretion, and reduced the number, weight and wetness of faecal droppings. There was no deaths or abnormalities in behaviour seen in the acute toxicity test. The aqueous extract displayed anti-microbial effects to three species of bacteria in anti-microbial test. CONCLUSION The findings of this study indicate that FPAE possesses anti-diarrhoeal property in rats and mice and confirm the ethnomedicinal use of Flos Populi as a valuable natural remedy for the treatment, management and/or control of diarrhoea. These results may support the fact that this plant is traditionally used to cure diarrhoea.

Abstract
CONTEXT Carpolobia lutea G. Don (Polygalaceae) leaf is reputable as an antidiarrheal agent among the Efik and Ibibio tribe of Akwa Ibom State, Nigeria. The crude extract is reported to show antidiarrheal and antiulcer effects in rodents. OBJECTIVE The isolation and characterization of drug molecules from the leaf fraction with antidiarrheal bioactivity and determination of mechanism of action are reported. MATERIAL AND METHODS Gradient extraction by maceration yielding n-hexane, chloroform, ethyl acetate, and ethanol fractions (770 mg/kg) were used to establish the fractions suitable for drug discovery. The antidiarrheal effect of the leaf fractions of Carpolobia lutea was evaluated using castor oil-induced diarrhea, castor oil-induced intestinal transit, and enteropooling. RESULTS Results indicate that all fractions produced a significant (p < 0.01-0.001) decrease in castor oil-induced diarrhea in rats. This effect was not antagonized by isosorbide dinitrate (150 mg/kg, p.o), diphenoxylate (5 × 10⁻³ mg/kg p.o) and yohimbine (1 mg/kg, s.c.) except for the chloroform fraction. The ethyl acetate fraction produced 100% inhibition of intestinal transit, an effect greater than pure drug. Phytochemical analysis of the ethyl acetate fraction yielded polyphenolic compounds. CONCLUSION The leaf fractions contain two types of antidiarrheal agents, one mediating its effect through α₁-presynaptic adrenoceptor while the other does not. Polyphenols isolated may in part lend credence for observed antidiarrheal activity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pyrenacantha staudtii Engl. (Icacinaceae) is a plant which is traditionally used for the treatment of blemnorrhea, hernia, insomnia, intestinal pain and diarrhea in Nigeria. Therefore the core aim of the present study is to evaluate antidiarrheal activity of Pyrenacantha staudtii aqueous extract (PSE). MATERIALS AND METHODS The antidiarrheal activity was evaluated using castor oil-induced diarrhea method. The effects of Pyrenacantha staudtii aqueous extract on gastrointestinal motility, intestinal transit and enteropooling were also examined in rodents. The acute toxicity effect of the aqueous extract of Pyrenacantha staudtii was also investigated. RESULTS Pyrenacantha staudtii aqueous extract (PSE, 100-400mg/kg, p.o.) produced dose-dependent and significant (P<0.05-0.01) protection of rats and mice against castor oil-induced diarrhea, inhibited intestinal transit, and delayed gastric emptying. PSE, produced dose-dependent and significant (P<0.05-0.01) antimotility effect, caused dose-related inhibition of castor-oil-induced enteropooling in animals, comparable to atropine (1mg/kg, p.o.). Like loperamide (10mg/kg, p.o.), PSE, dose-dependently and significantly (P<0.05-0.01) delayed the onset of castor-oil induced diarrhea, decreased the frequency of defecation, and reduced the severity of diarrhea in the rodents. Compared with control animals, PSE, dose-dependently and significantly (P<0.05-0.01) decreased the volume of castor oil-induced intestinal fluid secretion, and reduced the number, weight and wetness of fecal droppings. CONCLUSION The findings of this study indicate that PSE possesses antidiarrheal property in rats and mice. These findings confirm the ethnomedicinal use of Pyrenacantha staudtii leaf as a valuable natural remedy for the treatment, management and/or control of diarrhea.

Abstract
A series of 1-substituted imidazoles 1a-d and 2a-d were synthesized and screened for antispasmodic and antidiarrheal activities. Antispasmodic activity was tested at various concentrations on isolated tissue preparations; concentration-response curves were plotted and compared with atropine. All compounds were found to inhibit contraction of the guinea pig ileum. Castor oil-induced diarrhea model in rats was used for evaluation of antidiarrheal activity. Parameters such as intestinal transit and volume of intestinal fluid were measured for antidiarrheal activity at 40 mg kg-1 dose and compared with the standard drug loperamide at 6 mg kg-1 dose. Defecation frequency in the test group was found to be significantly lower (p < 0.01) compared to the control group and comparable with that of the standard. The present study reveals that the compounds exert antidiarrheal activity through possible inhibition of intestinal movement and reduction of capillary permeability in the abdominal cavity.
