摘 要 ：前人已证明人参和三七中富含的达马烷型人参皂甙在通常酸性水解下甙元即发生变化，而在弱酸（如50％醋酸，0.1N盐酸）条件下则形成次级皂甙。本文报道人参（ginseno－sides）和三七甙（notoginsenosides）的水溶液在水浴上加热亦分别形成相应的 C－20位去糖基的次级皂甙。联系到人参和三七均有在蒸煮加工后C－20位去糖基皂甙收率增大的趋势，似可认为人参和三七中的这类皂甙有相当一部分是在生药的加工泡制以及提取过程中形成的次级皂甙，而不一定是植物体的原生成分。

Abstract:The acid labile nature of ginsenosides,the saponins isolatid from ginseng and Sanchi-Ginseng [Panax notoginseng (Burk.)F.H. Chen]which is also a famous chinese traditional medicine, was observed on an early study on ginsenosides.ln this paper, we report that water solutions of ginseno ide Rb1, Re, RG1, and notoginsenoside R1 decomposed under the condition of heating on water bath to yield prosapogenins,which were shown to de mix-tures of C-20 epimer of ginsenoside Rg3,
