tIn order to supply uniform, genuine, good quality raw material to the pharmaceutical industries andto reduce the burden on natural stocks, cultivation of medicinal crops is the need of the hour. How-ever, improved varieties with optimum levels of active ingredients have so far not been developed ina number of important medicinal crops. Considering this, an investigation was undertaken to assessthe extent of variability amongst the natural populations of Gurmar (Gymnema sylvestre), an importantanti-diabetic plant of the Indian Systems of Medicine. Evaluation of the accessions for morphologicalparameters revealed highly significant differences for leaf related parameters viz. length, width, fresh aswell as dry weight and petiole length, which directly contribute to the biological yield of the plant. Fur-ther, a validated high performance liquid chromatography-diode array detection (HPLC-DAD) methodwas also developed for identification and quantification of bioactive principle i.e., gymnemagenin in agradient elution mode using solvent mixture composing of acetonitrile (solvent A), potassium dihydro-gen orthophosphate (10 mM, solvent B) both solvent A and B containing orthophosphoric acid (0.05%,v/v). Results revealed significant differences for gymnemagenin content amongst the accessions evalu-ated. These accessions could be used in breeding programs for development of cultivars with optimumlevels of gymnemagenin, which in turn may promote the cultivation of this high value medicinal crop.
