Chemical components of the root, stem and leaves of Panax japonicum var. major were compared with those of Radix ginseng and Radix notoginseng by TLC. The results showed that the total saponin of the root Panax japonicum var. major was closer to that of Radix ginseng and the total saponin of its stem and leaves was similar to Radix notoginseng. A better extractive technology was obtained after isolating and purifying the whole herb of Panax japonicum var. major by ethyl alcohol at different concentrations. The components were compared by TLC. The results showed that with 60% ethyl alcohol the yield of the total extract was 17.15%.
