本文报道了国内外八个人参样品用直接比色法、TLC-比色法、薄层光密度法、大孔树脂—比色法四种分析方法测定人参皂甙的含量,作了比较研究。实验结果表明,四种方法呈现一定的关系,其中薄层—比色法和大孔吸附树脂—比色法结果比较相近,直接比色法含量偏高,薄层光密度法适合分组皂甙及单体皂甙的测定。 In this paper, eight kinds of ginseng samples from home and abroad were reported by direct colorimetry, TLC-colorimetry, thin-layer densitometry, and macroporous resin-colorimetry. The contents of ginsenosides were determined and compared. The experimental results show that the four methods show a certain relationship, in which the results of the thin layer-colorimetric method and the macroporous resin-colorimetry method are similar, and the direct colorimetric method content is higher. The thin layer optical density method is suitable for grouping saponin and single Determination of body saponins.
