Abstract

From the dried roots of Panax ginseng two new minor dammarane saponins named koryoginsenoside-R1 and -R2 were isolated, along with fourteen known saponins. On the basis of spectral and chemical evidence, the structure of the new saponins were elucidated as 6-O-[trans butenoyl-(1-->6)-beta-D-glucopyranosyl]-20-O-beta-D- glucopyranosyl dammar-24-en-3 beta,6 alpha,12 beta,20(S)-tetrol and 3-O-[beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl]-20-O-[beta-D- glucopyranosyl-(1-->6)-beta-D-glucopyranosyl] dammar-22-en-3 beta,12 beta, 20(S),- 25-tetrol, respectively.

摘要

从人参干燥根中分离出两种新的次要达玛烷型皂苷，分别命名为高丽人参皂苷-R1和-R2，以及十四种已知皂苷。基于光谱和化学证据，新皂苷的结构分别被阐明为6-O-[反式丁烯酰基-(1→6)-β-D-吡喃葡萄糖基]-20-O-β-D-吡喃葡萄糖基达玛-24-烯-3β,6α,12β,20(S)-四醇和3-O-[β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡萄糖基]-20-O-[β-D-吡喃葡萄糖基-(1→6)-β-D-吡喃葡萄糖基]达玛-22-烯-3β,12β,20(S),-25-四醇。
