Abstract: Two dammarane-type saponins, that saponin A and saponin C have been isolated from the rhizome of Panax notoginseng (Burk.) F. H. Chen, and have been identified as ginsenoside Rgl (6,2O-di-O-β-D-glucosyl-20S-protopanax-triol), and ginsenoside-Rb2 (20S- protopanaxadiol- 3- [O-β-D-glucopyr-anosyl (1→ 2 )-β-D- glucopyranoside] -20- [O-α- L-arabinopyanosyl (1→ 6)-β-D-g1ucopyranoside] respectively.

摘要： 我们从三七(Panax notoginseng (Burk.) F. H. Chen) 根中分离得皂甙A和皂甙C.根据熔点、比旋光度及元素分析、红外、核磁证明皂甙A与 S. Shibata等从同属植物人参(Panax ginseng)中分离得到Ginsenoside-Rg1 (6, 20-di-O-β-D-glucosyl-20S-Protopanxatriol)是同一化合物；皂甙C与 Ginsenoside- Rb2(20S- Proto-panaxadiol-3-[0-β-D-glucopyranosy1 (l→2 )-β-D-glucopyranoside]-20-[O-α-L-arabino-pyranosyl(1→6)-β-D-glucopyranoside] )是同一化合物。
