Abstract
TLC, DCC and HPLC were used to study the ginsenoside composition of the main root, lateral root, rhizome, leaves and seeds of Panax ginseng cultivated in Jilin, China. Each of these methods has advantages of its own and the ensemble reveal the special features of Jilin ginseng. Total saponin content of various plant parts in Jilin ginseng showed a mid-range value as compared to those in ginsengs reported in literature. Fresh as well as sun-dried specimens from the same batch possessed a high percentage of Rg1 in the main root and this might account for the traditional preference of this plant part despite its lowest percentage of saponin in the whole plant. Large amounts of polar saponins were also observed in roots and rhizome of fresh Jilin ginseng, the nature and significance of which remained to be investigated.
