本文采用Shibata提取方法,以人参皂甙Re为标准品,通过对样品提取液的薄层分离,用香草醛—高氯酸比色法对不同产地、不同年生、不同规格的西洋参及其不同部位中的总皂甙和分组皂甙作了含量测定。结果表明:各种西洋参样品总皂甙含量差异较大;三醇型与二醇型皂甙含量比为1:2.93～1:3;花蕾皂甙含量最高。 In this paper, the Shibata extraction method was adopted, and ginsenoside Re was used as a standard. Through the thin layer separation of the sample extract, the vanillin-perchloric acid colorimetric method was used to analyze different origins, different years, and different specifications of American ginseng and its different parts. The total saponins and the saponins were measured. The results showed that the contents of total saponins of various American ginseng samples varied greatly; the ratio of triol-type and diol-type saponins was 1:2.93 to 1:3; the content of saponins was the highest.
