[PMID: 38530746 DOI: 10.1002/cbdv.202400394] [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: 02/14/2024] [Revised: 03/26/2024] [Accepted: 03/26/2024] [Indexed: 03/28/2024]
Abstract
Physochlaina is a genus of flowering plants belonging to the family Solanaceae and consists of 10 species distributed in various Asian countries. The species of the genus have been traditionally used to cure a variety of illnesses due to their highly valuable medicinal properties, including cancer, asthma, cough, weakness, stomachache, diarrhea, swelling, spasms, toothache, boils, ulcers, rheumatic pain, chronic bronchitis, gastric problems, abdominal pain, palpitation, and insomnia. The species have gained significant attention due to their remarkable ethnopharmacological and ethnomedicinal significance. The researchers have isolated so far 71 biologically active secondary metabolites from different Physochlaina species, which include flavonoids, alkaloids, coumarins, phenolic acids, iridoids, and sterols. These compounds exhibit diverse biological activities, such as antibacterial, anti-oxidant, anti-inflammatory, cytotoxic, and anticancer properties. The present review has been compiled with the intention of providing a comprehensive overview of the botany, distribution, traditional uses, phytochemical profile, and biological activities of the genus Physochlaina for future exploration of plant-based drugs and therapeutic approaches. The present review contributes to understanding the significant pharmacological potential of Physochlaina species and unraveling their chemical composition, highlighting their relevance in developing therapeutic agents. Till date, numerous pharmacological properties and isolated phytochemicals of Physochlaina species that support the species traditional and ethnobotanical history have been documented in a number of scientific publications. However, greater emphasis should be paid to in vivo investigations on various extracts and their phytoconstituents as well as mechanistic analysis to help drug developers better understand how to use Physochlaina species as significant therapeutic resources for herbal formulations using various techniques.

Abstract
Background: Kashmir Himalaya hosts the most diverse and rich flora in the world, which serves as grazing land for millions of small ruminants in the area. While most plant species are beneficial, some can be poisonous, causing economic losses and animal health issues for livestock. Consequently, this study is the first comprehensive report on the traditional phyto-toxicological knowledge in District Muzaffarabad and the assessment of its authenticity through experimental studies in rats. Methods: The data regarding traditional knowledge was gathered from 70 key respondents through semi-structured interviews, which was quantitatively analyzed and authenticated through plant extract testing on Wistar female rats and comparison with published resources. Results: A total of 46 poisonous plant species belonging to 23 families and 38 genera were reported to be poisonous in the study area. Results revealed that leaves were the most toxic plant parts (24 species, 52.1%), followed by the whole plant (18 species, 39.1%), stem (17 species, 36.9%), and seeds (10 species, 21.7%). At the organ level, liver as most susceptible affected by 13 species (28.2%), followed by the gastrointestinal tract (15 species, 32.6%), nervous system (13 species, 8.2%), dermis (8 species, 17.3%), renal (7 species, 15.2%), respiratory (4 species, 8.7%), cardiovascular system (3 species, 6.5%), and reproductive system (2 species, 4.3%). The poisonous plant species with high Relative frequency citation (RFC) and fidelity level (FL) were Nerium oleander (RFC, 0.6; FL, 100), Lantana camara (RFC, 0.6; FL, 100), and Ricinus communis (RFC, 0.6; FL, 100). Experimental assessment of acute toxicity assay in rats revealed that Nerium oleander was the most toxic plant with LD50 of (4,000 mg/kg), trailed by Ricinus communis (4,200 mg/kg), L. camara (4,500 mg/kg), and Datura stramonium (4,700 mg/kg); however, other plants showed moderate to mild toxicity. The major clinical observations were anorexia, piloerection, dyspnea, salivation, tachypnea, constipation, diarrhea, tremor, itchiness, and dullness. Conclusion: This study showed that numerous poisonous plants pose a significant risk to the livestock industry within Himalayan territory, leading to substantial economic losses. Consequently, it is of utmost importance to conduct further comprehensive studies on the phytotoxicity of plants.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Toxicity studies in appropriate animal models are an integral and very important component of pre-clinical studies in drug development. Brugmansia aurea lagerh. is used for both medicinal and non-medical purposes, including treating skin infections, different types of physical discomfort, inflammation, cough, hallucinations, and evil protection. AIM OF THE STUDY This study was designed to detect any hazardous effects of B. aurea on animals and find out its LD50. MATERIALS & METHODS An acute toxicity study was performed to find out the LD50 value and sub-acute toxicity study was performed to find out the toxicity on repeated dose administration till 28 days. Both studies were performed according to the organization of economic cooperation and development (OECD) 425 and 407 respectively. For the acute oral toxicity study, animals were divided into two groups, group I normal control (NC) and group II received a 2000mg/kg dose of B.aurea leaves extract. In the sub-acute toxicity study, male and female animals were divided into eight groups, I-IV for males and V-VIII for females received control, 100, 200 & 400mg/kg B. aurea leaves extract respectively. Hematological and biochemical markers were estimated at the end of each study. RESULTS Results revealed that no mortality and morbidity were observed in acute oral as well as sub-acute toxicity studies. Oxidative stress markers were increased significantly in all organs of the treatment groups in both studies. Animals significantly decreased their food and water intake in an acute oral toxicity study. A slight difference in renal function tests was observed in the acute oral toxicity study when compared with the normal control group. No significant change in histopathology was observed in both studies on selected organs. CONCLUSION This study concluded that B. aurea can be safely used for pharmacological purposes.

Toxic effect of Syzygium guineense ethanolic extract on female reproduction in rats: An evidence from a 10 week repeated-dose toxicity study. Heliyon 2023; 9:e17335. [PMID: 37383196 PMCID: PMC10293715 DOI: 10.1016/j.heliyon.2023.e17335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Revised: 06/10/2023] [Accepted: 06/14/2023] [Indexed: 06/30/2023] Open
Abstract
Introduction It has been reported that some herbal products affect reproduction. To date, reproductive toxicity of Syzygium guineense has not been investigated although the plant is widely used in treating fertility related problems. Thus, the objective of the current study was to investigate the toxic effects of 70% ethanol extract of S. guineense leaves on the reproductive function and histopathology of reproductive organs in female rats. Methods Eighty female Wistar albino rats were randomly divided into four groups where each group consisted of 20 rats. Rats in the first three groups were treated with S. guineense extract at doses of 250, 500 and 1000 mg/kg body weight, respectively. The fourth group served as a control group. The rats were treated for ten consecutive weeks. The length of estrous cycle, reproductive indices, pregnancy outcomes, and number of postnatal deaths were recorded. At necropsy, organ weight was measured, gross and histopathological examinations of ovaries, uterus, and vagina were conducted. Results Treatment of rats, with high dose (1000 mg/kg) of S. guineense, significantly prolonged the duration of estrous cycle and reduced weight of uterus and ovaries as well as the number of total and live birth pups. However, there were no significant changes observed in reproductive indices and gross morphology as well as histopathology of ovaries, uterus, and vagina. Conclusion Administration of high doses of S. guineense could be toxic to some aspects of the reproductive system of female rats and might also affect reproduction. Therefore, consuming high dose of S. guineense leaves is not recommended.

Monocrotaline induces acutely cerebrovascular lesions, astrogliosis and neuronal degeneration associated with behavior changes in rats: A model of vascular damage in perspective. Neurotoxicology 2023; 94:59-70.

Abstract
Pyrrolizidine alkaloids (PAs) are secondary plant metabolites playing an important role as phytotoxins in the plant defense mechanisms and can be present as contaminant in the food of humans and animals. The PA monocrotaline (MCT), one of the major plant derived toxin that affect humans and animals, is present in a high concentration in Crotalaria spp. (Leguminosae) seeds and can induce toxicity after consumption, characterized mainly by hepatotoxicity and pneumotoxicity. However, the effects of the ingestion of MCT in the central nervous system (CNS) are still poorly elucidated. Here we investigated the effects of MCT oral acute administration on the behavior and CNS toxicity in rats. Male adult Wistar were treated with MCT (109 mg/Kg, oral gavage) and three days later the Elevated Pluz Maze test demonstrated that MCT induced an anxiolytic-like effect, without changes in novelty habituation and in operational and spatial memory profiles. Histopathology revealed that the brain of MCT-intoxicated animals presented hyperemic vascular structures in the hippocampus, parahippocampal cortex and neocortex, mild perivascular edema in the neocortex, hemorrhagic focal area in the brain stem, hemorrhage and edema in the thalamus. MCT also induced neurotoxicity in the cortex and hippocampus, as revealed by Fluoro Jade-B and Cresyl Violet staining, as well astrocyte reactivity, revealed by immunocytochemistry for glial fibrillary acidic protein. Additionally, it was demonstrated by RT-qPCR that MCT induced up-regulation on mRNA expression of neuroinflammatory mediator, especially IL1β and CCL2 in the hippocampus and cortex, and down-regulation on mRNA expression of neurotrophins HGDF and BDNF in the cortex. Together, these results demonstrate that the ingestion of MCT induces cerebrovascular lesions and toxicity to neurons that are associated to astroglial cell response and neuroinflammation in the cortex and hippocampus of rats, highlighting CNS damages after acute intoxication, also putting in perspective it uses as a model for cerebrovascular damage.

Abstract
Background Ethnopharmacological relevance: Brugmansia, a genus of the Solanaceae family, has historically been utilized in many different parts of the world as an anti-inflammatory for treating skin infections, wounds, and bodily aches and pains. The current study aimed to investigate the potential benefits of a methanolic extract of Brugmansia aurea in the management of diabetes and underlying complications in alloxanized-induced diabetic rats. Materials and methods Animals were divided into nine groups (n = 6). Four groups received different standard oral hypoglycemic agents; three groups received 100, 200, and 400 mg/kg of B. aurea leaf extract for six consecutive weeks, and the remaining two were normal and disease control groups. All groups received alloxan (150 mg/kg) except for the normal control. Only those animals whose glucose levels were raised to 200 mg/dl were selected for the study. After a 6-week dosage period, various biochemical parameters, as well as HbA1c, antioxidant profile, oral glucose tolerance test (OGTT), insulin sensitivity, histopathology, and insulin resistance, were measured and compared with the untreated diabetic group. Results Brugmansia aurea leaf extract at a dose of 400 mg/kg showed potent antidiabetic activity by reducing blood glucose levels (p < 0.001) after 6 weeks of treatment. OGTT data showed that B. aurea exhibited significant (p < 0.001) glucose tolerance by significantly reducing blood glucose levels in just 2 h post-treatment. Other tests showed that plant extract significantly increased (p < 0.001) insulin sensitivity and decreased (p < 0.001) insulin resistance. The biochemical profile showed reduced triglyceride and cholesterol, while the antioxidant profile showed restoration of antioxidant enzymes in the pancreas, kidney, and liver tissues of treated rats. Conclusion The present study indicated that crude extracts of B. aurea increase insulin sensitivity and reduce hyperlipidemia in diabetic rats, which rationalizes the traditional medicinal use of this plant as an antidiabetic agent.

Abstract
INTRODUCTION Alkaloids and glycosides are the active ingredients of the herb Dendrobium nobile, which is used in traditional Chinese medicine. The pharmacological effects of alkaloids include neuroprotective effects and regulatory effects on glucose and lipid metabolism, while glycosides improve the immune system. The pharmacological activities of the above chemical components are significantly different. In practice, the stems of 3-year-old D. nobile are usually used as the main source of Dendrobii Caulis. However, it has not been reported whether this harvesting time is appropriate. OBJECTIVE The aim of this study was to compare the chemical characteristics of D. nobile in different growth years (1-3 years). METHODS In this study, ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UPLC-Q/TOF-MS) was employed to analyze the constituents of D. nobile. The relative abundance of each constituent was analyzed with multivariate statistical analyses to screen the characteristic constituents that contributed to the characterization and classification of D. nobile. Dendrobine, a component of D. nobile that is used for quality control according to the Chinese Pharmacopoeia, was assayed by gas chromatography. RESULTS As a result, 34 characteristic constituents (VIP > 2) were identified or tentatively identified as alkaloids and glycosides based on MS/MS data. Moreover, the content of alkaloids decreased over time, whereas the content of glycosides showed the opposite trend. The absolute quantification of dendrobine was consistent with the metabolomics results. CONCLUSION Our findings provide valuable information to optimize the harvest period and a reference for the clinical application of D. nobile.

Abstract
Poisonous plants cause tremendous economic losses to the livestock industry. These economic losses are deterioration in their health, decreased productivity, deformed offspring, and reduced longevity. The current study is the first comprehensive report on poisonous plants of Azad Jammu and Kashmir which systematically documents the phytotoxicological effect and mode of action in livestock. The information was gathered from 271 informants including 167 men and 104 women through semi-structured interviews and literature search through available databases. The data collected through interviews was analyzed with quantitative tools viz. the factor informant consensus and fidelity level. A total of 38 species of flowering plants belonging to 23 families and 38 genera were reported. Family Asteraceae (5 spp) was the most dominant, followed by Solanaceae (4 spp), Fabaceae (4 spp), Euphorbiaceae (4 spp) and Convolvulaceae (3 spp). Among all the species collected, herbs were the dominant life form (22 spp, 57.89%), trailed by shrubs (11 spp, 28.95%), and trees (5 spp, 13.16%). Whole plant toxicity was reported to be the highest (15 spp, 39.47%), followed by leaf toxicity (12 spp, 31.58%), seed toxicity (4 spp, 7.89%), fruit toxicity (3 spp, 10.53%), latex toxicity (2 spp, 5.26%), flowers toxicity (1 spp, 2.63%), and berries toxicity (1 spp, 2.63%). The most toxic route of administration was found oral (39 spp, 40.63%), followed by intraperitoneal (24 spp, 25%), and intravenous (21 spp, 21.88%). The most commonly affected organ was found liver (20.41%), followed by gastrointestinal tract (20.341%), CNS (16.33%), skin (14.29%), kidneys (12.24%), lungs (4.04%), reproductive organs (2.04%), spleen (1.75%), blood (1.75%), heart (1.75%), urinary tract (1.75%), and pancreas (1.75%). The maximum Fic value was found for dermatological disorders (0.91), followed by the endocrine system (0.90), gastrointestinal (0.82), neurology (0.77), nephrology (0.67), cardiovascular (0.67), urinary (0.67), respiratory (0.60), sexual (0.60) disorders. Senecio vulgaris, and Ageratum conyzoides were the most important plants with fidelity level (0.95) and (0.87). Nerium oleander, Lantana camara, Leucaena leucocephala, and Ricinus communis were the important poisonous plant with maximum fidelity level (100%). Ricinus communis with reported lowest LD50 (<20 mg/kg) was the top-ranked poisonous plant followed by Lantana camara and Justicia adhatoda (25-50 mg/kg), Nerium Oleander (157.37 mg/kg), and Datura innoxia (400 mg/kg). We found that knowledge about poisonous plants is less prevailing in the rural areas of Azad Kashmir compared to the knowledge about medicinal plants and poisonous nature of reported plants is due to production of toxic substances and presence of essential oils.

Wijayabandara K, Campbell S, Vitelli J, Shabbir A, Adkins S. Review of the Biology, Distribution, and Management of the Invasive Fireweed ( Senecio madagascariensis Poir). PLANTS (BASEL, SWITZERLAND) 2021; 11:107. [PMID: 35009110 PMCID: PMC8747533 DOI: 10.3390/plants11010107] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 12/22/2021] [Accepted: 12/24/2021] [Indexed: 06/14/2023]
Abstract
Whilst exotic invasive species are a major threat to natural and modified ecosystems around the world, management programs to reduce their impacts often fail due to a lack of information about their biology and how best to control them in various situations. This paper reviews the currently available information on the biology, distribution, and management options for the invasive weed Senecio madagascariensis Poir. (fireweed). In addition, we developed a model to predict the climatic suitability of this weed around the world based on the current climate. Senecio madagascariensis originates from southern Africa but it has been introduced to several other countries including Australia. Climatic suitability suggests that there are large areas around the world suitable for the weed's growth where it is currently not present. The weed poses a major threat to livestock industries in these countries through its ability to reduce pasture production and poison animals. A range of control techniques have been used to try and manage S. madagascariensis. This paper highlights how a better understanding of the biology of S. madagascariensis can help determine the most effective treatments to impose and to further develop integrated management strategies. Besides using traditional approaches, the use of competitive pastures and more tolerant livestock (such as sheep and goats) are some of the other options recommended as part of an integrated approach. On-going research to identify host-specific biological control agents is also considered a priority.

[PMID: 33571613 DOI: 10.1016/j.jep.2021.113910] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/07/2020] [Revised: 01/21/2021] [Accepted: 02/04/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Brugmansia belongs to the Solanaceae family and contains approximately 7-8 species distributed in America, Europe, Africa, and Asia. The genus Brugmansia plants are used in the traditional medicine of different parts of the world for the treatment of inflammations, rheumatic arthritis, wounds, skin infections, headache, asthma, colic, aches, and so on. AIM OF THE REVIEW To the best of our knowledge, this is the first review study that focuses on the phytochemistry, pharmacology, toxicity, and traditional uses of Brugmansia species in order to understand the link between the traditional uses, phytochemistry, and modern therapeutic uses, and provide a scientific fundamental for further research in the phytochemical and pharmacological activities of their species. MATERIALS AND METHODS The information reported in this study was retrieved from the scientific database such as ScienceDirect, PubMed, Springer, CNKI, Wiley, Google Scholar, and Baidu Scholar, up until May 2020. The key search word was "Brugmansia." Additionally, information was derived by search on the reference lists of included articles and Ph.D. dissertations. RESULTS As traditional uses, Brugmansia species are used against a wide range of diseases such as body pain, inflammatory conditions, skin infection, wound, and other diseases. Also, these species are used as a hallucinogen, protection from evil, and magical rituals. Phytochemical investigations have led to reporting approximately 189 chemical compounds in this genus. Among these components, tropane alkaloids, terpenes, and flavonoids are the most representative components of Brugmansia species. The plant extracts and chemical constituents of Brugmansia species exhibit a broad spectrum of biological and pharmacological activities, including anti-inflammatory, cytotoxic, antioxidant, antibacterial, antispasmodic, anti-asthmatic, antinociceptive, antiprotozoal activities, and so on. CONCLUSION This review summarized and analyzed the information of traditional uses, phytochemical, pharmacological activities, and toxicity of the genus Brugmansia plants, which show their species have interesting chemical constituents with different biological activities. The traditional uses of some species from this genus have been estimated by pharmacological activities, such as the anti-inflammatory, antispasmodic, antiasthma, antinociceptive, anti-addictive, and antiprotozoal activity. However, the traditional uses of many species have not been confirmed, also the secondary metabolites of the many species have not yet been determined and have never been pharmacologically estimated. Considerably more research is needed to assert the ethnopharmacological uses, determine the chemical constituents, toxicity, and pharmacological activities of the genus Brugmansia species. The present review will be helpful for further research in the phytochemistry and pharmacology of Brugmansia species.

Sub-chronic toxicity of ethanol leaf extract of Syzygium guineense on the biochemical parameters and histopathology of liver and kidney in the rats. Toxicol Rep 2021; 8:822-828. [PMID: 33868962 PMCID: PMC8044796 DOI: 10.1016/j.toxrep.2021.03.032] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Revised: 03/28/2021] [Accepted: 03/31/2021] [Indexed: 11/29/2022] Open
Abstract
Long-term use of Syzygium guineense leaf extract reduced the food intake and weight gain in rats. The serum level of liver and kidney enzymes of rats was increased by the treatment of high dose of Syzygium guineense leaf. Use of Syzygium guineense leaf extract showed hypoglycemic effect in rats.
Background Syzygium guineense Wall. leaf is being used as a traditional medicine against hypertension and diabetes mellitus. Unlike its efficacy, the safety profile of this plant upon long-term administration has not been investigated yet. Therefore, this study investigated the sub-chronic toxicity of S. guineense leaves in rats. Methods Wistar albino rats, 10/sex/group were randomly assigned into four groups. Group I-III respectively received 250, 500, and 1000 mg/kg of body weight of 70 % ethanol extract ofS. guineense leaves for 90 consecutive days. Group IV (control) received distilled water. Throughout the experiment, clinical observations were carried out, food intake and weight of the rats also were measured. Finally, different biochemical parameters, organ weight, and histopathology of liver and kidneys were evaluated. Results Administration of 70 % ethanol extract ofS. guineense leaves decreased food intake and body weight gain of the test animals. Rats treated with 1000 mg/kg of S. guineense extract showed significantly increased serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase levels. Serum urea levels also increased in female rats treated with 500 and 1000 mg/kg body weight of S. guineense. Moreover, the blood glucose level of rats treated with 1000 mg/kg body weight was significantly decreased compared to the control group. However, the histology of the liver and kidneys were not significantly altered by any of the doses administered. Conclusion Administration ofS. guineense in rats at a dose of 1000 mg/kg body weight affected the food consumption, weight gain, and serum levels of liver and kidney enzymes suggesting that S. guineense intake at high doses may be toxic. Therefore, liberal consumption of S. guineense leaves should be taken curiously and cautiously.

Abstract
Many natural products have biological effects on humans and animals. Poisoning caused by natural products is common in clinical toxicology cases. Liquid chromatography-high-resolution-mass spectrometry (LC-HRMS) has recently emerged as a powerful analytical tool for large-scale target screening, and the application of LC-HRMS can be expanded to evaluate potential natural product poisoning in clinical cases. We report the construction of an LC-HRMS spectral library of 95 natural products commonly implicated in poisoning, and an LC-HRMS assay was validated for definitive detection of natural products in urine and serum samples. For each compound, the limit of detection (LOD) was determined in the analytical range of 1.0 - 1000 ng/mL for urine samples and 0.50 - 500 ng/mL for serum samples. The mean (SD) of matrix effects for urine samples and that for serum samples were both -21% (22%), and the mean (SD) of recovery for serum samples was 89% (26%). The LC-HRMS assay was successfully applied to identify natural products in clinical cases. The spectral library parameters of each compound are provided in the supplementary material to aid other laboratories in identification of unknown natural toxins and development of similar methods on different mass spectrometry platforms.

Abstract
Introduction: Herbal medicines (HMs) have shown therapeutic and toxicological potentials. Thus, the WHO expanded the pharmacovigilance (PVG) scope to include HMs. This study appraised the state of PVG system in Nigeria for the safety monitoring of HMs using WHO core PVG indicators. Methods: Between January and June 2019, 39 PVG experts were requested to independently appraise the PVG system in Nigeria for safety monitoring of HMs using WHO PVG core structural (CSIs), process (CPIs) and outcome (COIs) indicators. The 27 indicators (CSIs = 10, CPIs = 9 and COIs = 8) were scored 3, 2, 1 and 0 for adequate, fairly adequate, inadequate and uncertain states, respectively. CSIs index (CSII) was determined by dividing the summation of CSIs mean score by total obtainable score (30) and expressed in percentage. This was applied to CPIs and COIs to obtain CPIs index (CPII) and COIs index (COII), respectively. Results: The mean ± standard deviation (SD) of participants’ age was 43.6 ± 10.3 years with mean ± SD work experience of 15.3 ± 9.3 years. Majority had doctoral degree (35.9%; 14/39; P >0.05) and were medical doctors (28.2%; 11/39; P > 0.05). Twelve of the 27 indicators scored at least 2.0 and CSIs, CPIs, and COIs accounted for 75.0% (9/12), 0.0% (0/12) and 25.0% (3/12), respectively (P < 0.05). The total mean score was 27.3 ± 0.2 for CSIs as against 8.0 ± 0.3 for CPIs and 11.2 ± 0.4 for COIs (P < 0.05). The CSII, CPII and COII were 91.0%; 29.6% and 46.7%, respectively (P < 0.05). Conclusion: Most of the structural elements are in place for safety monitoring of HMs in Nigeria. However, the process and outcome of PVG indicate an inadequate state. Thus, deliberate efforts are required to ensure the realization of PVG objectives.

Abstract
Hepatotoxic and genotoxic pyrrolizidine alkaloids have been involved in the acute poisoning of animals and humans. Crotalaria (Fabaceae) species contain these alkaloids. In this work, the diversity and distribution of pyrrolizidine alkaloids in roots, leaves, flowers, and seeds of Crotalaria pallida, Crotalaria maypurensis, Crotalaria retusa, Crotalaria spectabilis, Crotalaria incana, and Crotalaria nitens were studied. Matrix solid-phase dispersion and ultra-high-performance liquid chromatography coupled with Orbitrap mass spectrometry were successfully employed in pyrrolizidine alkaloids extraction and analysis, respectively. Forty-five pyrrolizidine alkaloids were detected and their identification was based on the mass spectrometry accurate mass measurement and fragmentation pattern analysis. The cyclic retronecine-type diesters monocrotaline, crotaleschenine, integerrimine, usaramine, and their N-oxides were predominantly present. Five novel alkaloids were identified for the first time in Crotalaria species, namely 14-hydroxymonocrotaline, 12-acetylcrotaleschenine, 12-acetylmonocrotaline, 12-acetylintegerrimine, and dihydrointegerrimine. Due to a lack of commercially available standards, the response factor of monocrotaline was used for quantification of pyrrolizidine alkaloids and their N-oxides. Seeds and flowers possessed higher pyrrolizidine alkaloids amounts than roots and leaves. Due to their 1,2-unsaturated pyrrolizidine alkaloids content, the ingestion of Crotalaria plant seeds or other parts through herbal products, infusions, or natural remedies is a serious health threat to humans and livestock.

Abstract
Antirhea borbonica (A. borbonica) is an endemic plant from the Mascarene archipelago in the Indian Ocean commonly used in traditional medicine for its health benefits. This study aims (1) at exploring polyphenols profiles from two types of extracts—aqueous (herbal infusion) and acetonic (polyphenol rich) extracts from A. borbonica leaves—and (2) at evaluating their potential toxicity in vivo for the first time. We first demonstrated that, whatever type of extraction is used, both extracts displayed significant antioxidant properties and acid phenolic and flavonoid contents. By using selective liquid chromatography–tandem mass spectrometry, we performed polyphenol identification and quantification. Among the 19 identified polyphenols, we reported that the main ones were caffeic acid derivatives and quercetin-3-O-rutinoside. Then, we performed a Fish Embryo Acute Toxicity test to assess the toxicity of both extracts following the Organisation for Economic Cooperation and Development (OECD) guidelines. In both zebrafish embryos and larvae, the polyphenols-rich extract obtained by acetonic extraction followed by evaporation and resuspension in water exhibits a higher toxic effect with a median lethal concentration (LC50: 5.6 g/L) compared to the aqueous extract (LC50: 20.3 g/L). Our data also reveal that at non-lethal concentrations of 2.3 and 7.2 g/L for the polyphenol-rich extract and herbal infusion, respectively, morphological malformations such as spinal curvature, pericardial edema, and developmental delay may occur. In conclusion, our study strongly suggests that the evaluation of the toxicity of medicinal plants should be systematically carried out and considered when studying therapeutic effects on living organisms.

Abstract
INTRODUCTION Indolizines are structural isomers with indoles. Although several indole-based commercial drugs are available in the market, none of the indolizine-based drugs are available up-to-date. Natural and synthetic indolizines have a wide-range of pharmaceutical importance such as antitumor, antimycobacterial, antagonist, and antiproliferative activities. This prompted us to search and collect all possible data about the pharmacological importance of indolizine to open an avenue to the researchers in exploring more medicinal applications of such biologically important compounds. AREAS COVERED The current review article covers the advancements in the biological and pharmacological activities of indolizine-based compounds during the last decade. The covered areas of this work involved anticancer, anti-HIV-1, anti-inflammatory, antimicrobial, anti-tubercular, larvicidal, anti-schizophrenia, CRTh2 antagonist's activities in addition to enzymatic inhibitory activity. EXPERT OPINION The discovery of indolizine drugs will be a major breakthrough as compared with their widely available drug-containing indole isosteres. Major work collected here was focused on anticancer, anti-tubercular, anti-inflammatory, and enzymatic inhibitory activities. The SAR study of the reported biologically active indolizines is summarized throughout the review whenever highlighted to the rationale the behavior of inhibitory action. Several indolizines with certain functions provided great enhancement in the therapeutic activities comparing with reference drugs.

Abstract
Endocannabinoid pharmacology is now relatively well understood with a number of endocannabinoids and endogenous cannabinoid neurotransmitters identified and the pharmacokinetics relatively well ascertained. Further, the cannabinoid receptors are now molecularly and pharmacologically characterised and the cell processes involved in endocannabinoid transcription, synthesis, post-translational modification and protein expression are reported. Endogenous cannabinoids have been shown to have key roles in immune and pain pathways and neuro-behavioural signalling including appetite regulation. Significant recent interest has thus been shown in understanding these pathways to guide the development of agents that inhibit the natural catabolism of endogenous cannabinoids to modify pain and appetite, and to synthesise antagonists for the treatment of disease such as obesity. This research is concurrent with the renewed clinical interest in exogenous cannabinoids and their use in disease. However, the complex pharmacology and physiological effects of exogenous cannabinoids, either as individual components or in combination, as extracts or via administration of the whole plant in humans, are less well known. Yet as with all other therapeutics, including those derived from plants, knowledge of the pharmacokinetics and dynamics of the complete plant, the individual chemical molecules and their synthetic versions, including formulations and excipients is a standard part of drug development. This article covers the key pharmacological knowledge required to guide further exploration of the toxicity and efficacy of different cannabinoids and their formulations in blinded placebo-controlled studies.

Abstract
Pyrrolizidine alkaloids (PAs) are natural toxins found in some genera of the family Asteraceae. However, it has not been reported whether PAs are present in the widely used Asteraceae plant Artemisia capillaris Thunb. (A. capillaris). The purpose of this study was to establish a sensitive and rapid UPLC-MS/MS method together with chemometrics analysis for simultaneous determination and risk assessment of PAs in A. capillaris. The developed UPLC-MS/MS method was validated and was confirmed to display desirable high selectivity, precision and accuracy. Risk assessment was conducted according to the European Medicines Agency (EMA) guideline. Chemometrics analysis was performed with hierarchical clustering analysis and principal component analysis to characterize the differences between PAs of A. capillaris. Finally, PAs were found in 29 out of 30 samples and at least two were detected in each sample, besides, more than half of the samples exceeded the EMA baseline. Nevertheless, the chemometrics results suggested that the PAs contents of A. capillaris from different sources varied significantly. The method was successfully applied to the detection and risk evaluation of PAs-containing A. capillaris for the first time. This study should provide a meaningful reference for the rational and safe use of A. capillaris.

[PMID: 30372906 DOI: 10.1016/j.biopha.2018.09.124] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2018] [Revised: 09/18/2018] [Accepted: 09/19/2018] [Indexed: 02/07/2023] Open
Abstract
An-te-xiao capsule consists of total alkaloids from the dried whole plantof Solanum lyratum, and showed antitumor effects in our previous study. However, its inhibitory effect on multiple non-small cell lung cancer (NSCLC) cell lines and the underlying mechanisms have not been elucidated clearly. This study sought to investigate the inhibitory effects of An-te-xiao capsule on three main types of NSCLC cell lines (A549, NCI-H460, and NCI-H520) in vitro and in vivo and the underlying mechanisms of action including its potential anti-angiogenesis effects. An-te-xiao capsule showed no acute oral toxicity in mice, and significantly prolonged survival time in a mouse model of Lewis tumor xenograft. The inhibition of A549, NCI-H460, and NCI-H520 cells by An-te-xiao capsule was reflected in its effects on tumor growth, histopathological changes, tumor microvessel density (MVD), cell cycle regulatory proteins, and cell apoptosis. In vitro, An-te-xiao capsule repressed migration, invasion, and tube formation of tumor-derived vascular endothelial cells (Td-ECs), which were obtained using a co-culture system, in the presence or absence of vascular endothelial growth factor (VEGF) at safe concentrations selected using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Moreover, An-te-xiao capsule inhibited the secretion of VEGF by A549 cells in the co-culture system and suppressed the phosphorylation of VEGF receptor 2 (VEGFR2). Taken together, An-te-xiao capsule has potential for treating NSCLC.

Abstract
Only a small percentage of insect species are pests. However, pest species cause significant losses in agricultural and forest crops, and many are vectors of diseases. Currently, many scientists are focused on developing new tools to control insect populations, including secondary plant metabolites, e.g., alkaloids, glycoalkaloids, terpenoids, organic acids and alcohols, which show promise for use in plant protection. These compounds can affect insects at all levels of biological organization, but their action generally disturbs cellular and physiological processes, e.g., by altering redox balance, hormonal regulation, neuronal signalization or reproduction in exposed individuals. Secondary plant metabolites cause toxic effects that can be observed at both lethal and sublethal levels, but the most important effect is repellence. Plants from the Solanaceae family, which contains numerous economically and ecologically important species, produce various substances that affect insects belonging to most orders, particularly herbivorous insects and other pests. Many compounds possess insecticidal properties, but they are also classified as molluscides, acaricides, nematocides, fungicides and bactericides. In this paper, we present data on the sublethal and lethal toxicity caused by pure metabolites and crude extracts obtained from Solanaceae plants. Pure substances as well as water and/or alcohol extracts cause lethal and sublethal effects in insects, which is important from the economical point of view. We discuss the results of our study and their relevance to plant protection and management.
