黑刺菝葜中的甾体皂甙研究

Steroidal saponins from Smilax scobinicaulis

从黑刺菝葜 (Smilax scobinicaulis Wringh C.H.)根中首次分离得到 2个甾体皂甙化合物 ,经理化、光谱分析及与标准样品对照 ,鉴定化合物 为拉克索皂甙元 - 3- O- [α- L -吡喃阿拉伯糖基 - (1→ 6 ) ]-β- D-吡喃葡萄糖甙 ,化合物 为拉克索皂甙元 - 3- O- [β- D-吡喃葡萄糖基 - (1→ 4 ) ]- [α- L -吡喃阿拉伯糖基 - (1→ 6 ) ]-β- D-吡喃葡萄糖甙。

Two steroidal saponins were first isolated from 95% ethanolic extract of the rhizome of Smilax scobinicaulis Wright C.H..Their structures were established on the basis of spectral and chemical methods as laxogenin 3 O [α L arabinopyranosyl (1→6)] β D glucopyranoside and laxogenin 3 O [β D glucopyrnosyl (1→4)] [α L arabinopyranosyl (1→6)] β D glucopyranoside.
