Ethnopharmacological RelevanceTylophora indica (Burm. f.) Merr. commonly known as ananthamool is a climbing perennial plant which is widely used in Indian traditional medicine. T. indica exhibits diverse range of pharmacological activities viz. antiasthmatic, antidiarrheal, anticancer, antiarthritic, antiepileptic, anti-inflammatory etc. AIM OF THE STUDY: Present review aims to grant an up-to-date insight into the botany, ethnopharmacology, phytochemistry, pharmacology and toxicology of T. indica, exploring its future research and opportunities.Material And MethodsComprehensive information regarding T. indica was collected using the keywords Tylophora indica or Indian ipecac or ananthamool in various electronic databases ACS, Google Scholar, Pubmed, Science Direct, SciFinder, Web of Science, Springer Link and Wiley. In addition, some books and book chapters were also consulted.ResultsT. indica has been traditionally used in India, Bangladesh and Sri Lanka in the form of various preparations like powder, decoction, pulp, paste and extract alone or in combination with other herbs against various ailments like skin disorders, inflammation, cough, asthma, diarrhea, cancer, microbial infections etc. In vitro and in vivo pharmacological studies on T. indica revealed its potential as antiasthmatic, antiallergic, anti-inflammatory, anticancer, antimicrobial, antioxidant, antidiarrheal agent etc. A diverse range of phytochemical constituents have been isolated and identified from T. indica namely alkaloids (Tylophorine, Tylophorinine, Tylophorinidine), flavonoids (Kaempferol & Quercetin) terpenoids (α-Amyrin & β-Amyrin) and sterols (β-sitosetrol). Amongst which phenanthroindolizidine alkaloids isolated from roots and leaves are largely explored and considered to be the most active constituent of plant.ConclusionPresent review provides an insight into botany, ethnopharmacology, phytochemistry, pharmacology and toxicology of T. indica. As an important traditional Indian medicine, few ethnobotanicals use of T. indica have been supported by modern pharmacological studies, especially in asthma, cancer and inflammation. Among compounds from various phytochemical classes, phenanthoindolizidine alkaloids namely tylophorine and tylophorinidine alkaloids have been considered as bioactive components of the plant and widely investigated. However, further identification, isolation and quantification employing some advanced hyphenated techniques viz. LC-MS/MS, LC-NMR to discover new pharmacologically active phytoconstituents in the management of different diseases. Several investigators have highlighted possible therapeutic roles of T. indica extracts and isolated compounds. Moreover, information about various aspects of T. indica pertaining to phytochemistry, toxicology and quality control are still unresolved. Further in-depth studies are required to discover key features viz. structure activity relationships, mode of action, safety and toxicity and therapeutic potentials T. indica in clinical settings.Copyright © 2020 Elsevier B.V.
