摘要：Gymnema sylvestre (Retz.) R. Br. ex Sm., a rich source with gymnemic acid, has been used to treat diabetessince past 2000 years. A study was conducted to evaluate the genetic diversity of G.sylvestre collected from twelvedifferent geographical locations of Karnataka state of India using ISSR molecular markers. A total of 80 clear andreproducible bands were amplified with different lengths using the 10 selected ISSR primers, of which 68 (85%) werepolymorphic and remaining 12 (15%) were monomorphic. The high level of genetic variation (85%) observed among thepopulations of G.sylvestre implied the need to conserve populations to maintain within this species. As an importantmedicinal plant, it would be wise to save populations of G.sylvestre in different regions in order to limit population declinescaused by over exploitation
