摘要
从黄精的乙醇提取物的正丁醇萃取相中分离到3个甾体皂苷,经1H-NMR1、3C-NMR1、35DEPT测定分析,鉴定出这3个化合物分别是薯蓣皂苷元-3-O--βD-吡喃葡萄糖基(1→3)--βD-吡喃葡萄糖基(1→4)-[-αL-吡喃鼠李糖基(1→2)]--βD-吡喃葡萄糖苷,薯蓣皂苷元-3-O--αL-吡喃鼠李糖基(1→2)-[-αL-吡喃鼠李糖基(1→4)]--βD-吡喃葡萄糖苷,薯蓣皂苷元-3-O--αL-吡喃鼠李糖基(1→2)-[-βD-吡喃葡萄糖基(1→4)]--βD-吡喃葡萄糖苷。其中皂苷Ⅰ和Ⅲ在黄精中为首次报道。
Three steroidal saponins were isolated from N. butanol extracts of Rhizoma polygonati. Their chemical structure were elucidated by means of 1 H-NMR, ^13C-NMR, ^135DEPT spectroscopic analyses. They are 3-O-β-D-glucopyranosyl （1 → 3 ）-β-D-glucopyranosyl （1 → 4 ）-[ a-L- rhamnopyranosyl（ 1 → 2） ]-β-D-glucopyranosyl-diosgenin, 3-O-a-L-rhamnopyranosyl （ 1 → 4 ）-[a-L- rhamnopyranosyl （ 1 → 2 ）]-~D-glucopyranosyl-diosgenin, 3-O-β-D-glucopyranosyl （ 1→ 4 ）-[ a-L- rhamnopyranosyl（1→2）]-β-D-glucopyranosyl-diosgenin. Compounds Ⅰ and Ⅲ are reported for the first time from Rhizoma polygonati.
