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%.
通过薄层色谱法（TLC）比较了大叶三七根、茎、叶的化学成分与人参和三七的化学成分。结果表明，大叶三七根的总皂苷与人参更接近，其茎和叶的总皂苷与三七相似。采用不同浓度乙醇对大叶三七全草进行分离纯化后，获得了较好的提取工艺。通过薄层色谱法对成分进行比较。结果表明，用60%乙醇时，总提取物的得率为17.15%。
