Summary Gymnema sylvestre is regarded as one of the plants with potent anti diabetic properties. This plant is also used for controlling obesity in the form of Gymnema tea. The active compound of the plant is a group of acids termed as gymnemic acids. It has been observed that there could be a possible link between obesity, Gymnemic acids and diabetes. This review will try to put forth an overall idea about the plant as well as present a molecular perspective linking the common medicine to the most common metabolic disorders.
The phyto-constituents of Gymnema sylvestre are used in the treatment of diabetes and obesity. The present work reports on the extraction of gymnemic acid through gymnemagenin from callus cultures of G. sylvestre. Components were separated on pre-coated silica gel 60 GF254 plates with chloroform:methanol (8:2) and scanned using a densitometric scanner at 205 nm in the near-UV region. Linearity of determination of gymnemagenin was observed in the range 2-10 microg. The average percentage recovery of gymnemagenin from leaf callus extracts was 98.9+/-0.3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
