摘要: 从仙茅(Curculigo orchioides)中分离得到2个新的环阿尔廷醇型三萜皂苷,通过波谱分析鉴定了它们的化学结构,即3β, 11α, 16β-三羟基环阿尔廷烷-24-酮-3-O-[β-D-吡喃葡糖(1→3)-β-D-吡喃葡糖(1→2)-β-D-吡喃葡糖]-16-O-α-L-阿拉伯糖苷(1)和(24S)-3β,11α,16β,24-四羟基环阿尔廷烷-3-O-[β-D-吡喃葡糖(1→3)-β-D-吡喃葡糖(1→2)-β-D-吡喃葡糖]-24-O-β-D-吡喃葡糖苷(2)。

Abstract: Two new cycloartane-type triterpene glycosides were isolated from rhizomes of Curculigo orchioides. Their structures were elucidated as 3β,11α,16β-trihydroxycycloartane-24-one-3-O-[β-D-glucopyranosyl(1→3)-β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl]-16-O-α-L-arabinopyranoside(1) and (24S)-3β,11α,16β,24-tetrahydroxycycloartane-3-O[β-D-glucopyranosyl(1→3)-β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl]-24-O-β-D-glucopyranodide (2), respectively, on the basis of their spectroscopic methods.
