Baccharoides anthelmintica (L.) Moench: A Review on Ethnomedicinal, Phytochemical, Pharmacological and Toxicological Profile

Baccharoides anthelmintica (L.) Moench is a popular medicinal plant with a long history of use in several traditional remedies to cure a variety of diseases including; its effect on the central nervous system, gastrointestinal tract, metabolism, kidneys, gynecology, skin diseases, and general health. The present review aims to provide the latest, organized information on toxicological, pharmacological, phytochemical, and ethnomedicinal applications of Baccharoides anthelmintica. For this; several well-known searchable websites (search engines) like; Web of Science, Google Scholar, Scopus-Elsevier, Taylor & Francis, Springer, and DOAJ, were used to empirically investigate the knowledge of this useful medicinal plant. Based on previous studies, the pharmacological action of B. anthelmintica is due to various secondary metabolites including alkaloids, terpenoids, lignans, steroids, and other phytoconstituents. Hence, the present study recorded 225 phytochemicals obtained from different parts of the plant, where the steroids and derivatives (48), terpenes and sesquiterpenes (46), flavonoids and derivatives (41), fatty acids and derivatives (40), phenolic acids (12), triterpenes (11), chalcones (06), diterpenes (01) and miscellaneous (20) were reported. The present review also covered the pharmacological importance, including antioxidant, antimicrobial, antiparasitic, antidiabetic, hypolipidemic action, liver disease, anticancer potential, anti-HIV, antiosteoporotic action, antitoxic action, skin disorder, wound healing and immunomodulatory activity, systemic infection, and treatment of neurodegenerative diseases etc. The review concluded that B. anthelmintica has several pharmacological activities, which were due to the presence of secondary metabolites present in it, and thus indicates the importance of medicinal value of this plant. Hence, B. anthelmintica may be a good source for developing a lead molecule in the process of new drug discovery and development. More study is required to determine the pharmacokinetics, mechanism of action, long-term toxicology testing, safe dosage, and possible interactions with other herbs/drugs.

Influence of methyl jasmonate and salicylic acid on Rhamnetin production in adventitious root cultures of Baccharoides anthelmintica (L.) Moench

We developed adventitious roots from the leaf explants of Baccharoides anthelmintica (L.) Moench (syn. Vernonia anthelmintica) cultured on Murashige and Skoog (MS) medium. We tested MS and White's media fortified with different Indole Butyric Acid concentrations for their effect on root biomass production. MS medium supplemented with 1 mg L^-1 IBA produced the highest biomass of adventitious roots compared to White's medium. HPLC and LC-Q-TOF analyses confirmed the ability of the adventitious roots of B. anthelmintica to produce rhamnetin. When the 15-day old root cultures were treated with 0.6 mM methyl jasmonate, on the 6th-day, rhamnetin content was enhanced to 0.443 mg g^-1DW, which was 1.5 folds compared to untreated roots. Similarly, Salicylic acid also improved rhamnetin production to 0.36 mg g^-1 DW, which was 1.2 folds increment compared to untreated roots. Rhamnetin content in the roots of field-grown plants was 0.112 mg g^-1DW.
