摘要
百合科植物黑果拔葜根茎的甲醇提取物,经硅胶柱层析及制备性薄层层析,分离得到两种甾体皂甙成分——黑果拔葜皂甙 A 和黑果拔葜皂甙 B。通过乙酰化、酸水解、红外光谱、质谱和一些物理常数等的测定,推断黑果拔葜皂甙 A 的化学结构为知母皂甙元-3-0-[β-D-葡萄吡喃糖基(1→?)]-[-L-鼠李吡喃糖基(1→?)]-B-D-葡萄吡喃糖甙。灭螺活性试验表明黑果拔葜粗皂甙及纯品皂甙 A 均有明显的杀螺作用。
Two steroidal saponins named Heiguobaqia saponin A and Heiguobaqia saponin B were isolated from the methanol extract of rhizome of Smilax glauco-china Warb (Liliaceae) by chromatographic method.On the basis of acetylation acid hydrolysis、Infrared Spectrum、Mass Spectrum and some physical contants etc.The chemical structure of Saponin A has been elucidated and identified as sarsasapogenin-3-0[β-D-glucopyranosyl(1→?)] -[α-L-rhamnopyranosyl (1→?)]-β-D-glucopyranoside.Heiguobaqia Saponins weretestcd for molluscicidal activity.The crude,saponins ane Saponin A were shown to have strong killing activity.
