A new steroidal saponin was isolated from the bulbs of Allium ampeloprasum var. porrumL. On the basis of chemical evidence, comprehensive spectroscopic analyses and comparison of known compounds, its structure was established as (3β,5α,6β,25R)-6-[(β-D-glucopyranosyl)oxy]-spirostan-3-yl O-β-D-glucopyranosyl-(1→2)-O-[β-D-glucopyranosyl-(1→3)]-β-D-galactopyranoside. Results of the present study indicated
从葱属鳞茎的鳞茎中分离出一种新的甾体皂苷。稀饭 在化学证据,综合光谱分析和已知化合物比较的基础上,确定其结构为(3β,5α,6β,25R)-6-[(β-D-吡喃葡萄糖基)氧基] -spirostan-3-yl O -β-D-吡喃葡萄糖基-(1→2)-O- [β-D-吡喃葡萄糖基-(1→3)]-β-D-吡喃半乳糖苷。本研究的结果表明,甾体皂苷在体外试验中显示出溶血作用,并在体内模型中表现出抗炎活性和胃保护作用。
