Abstract

Three new spirostanol saponins have been isolated from the seeds of Allium tuberosum. On the basis of acid hydrolysis and comprehensive spectroscopic analysis, their structures were established as tuberoside J, (25R)-5alpha-spirostan-2alpha,3beta,27-triol 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranoside; tuberoside K, (25R)-5alpha-spirostan-2alpha,3beta,27-triol 3-O-alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->4)]-beta-D-glucopyranoside; and tuberoside L, 27-O-beta-D-glucopyranosyl-(25R)-5alpha-spirostan-2alpha,3beta,27-triol 3-O-alpha-D-rhamnopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->4)]-beta-D-glucopyranoside.

摘要

从韭菜籽中分离出了三种新的螺旋甾烷醇皂苷。基于酸水解和综合光谱分析，确定它们的结构分别为韭菜苷J，(25R)-5α-螺旋甾烷-2α,3β,27-三醇3-O-α-L-鼠李糖吡喃糖基-(1→2)-β-D-葡萄糖吡喃糖苷；韭菜苷K，(25R)-5α-螺旋甾烷-2α,3β,27-三醇3-O-α-L-鼠李糖吡喃糖基-(1→2)-[α-L-鼠李糖吡喃糖基-(1→4)]-β-D-葡萄糖吡喃糖苷；以及韭菜苷L，27-O-β-D-葡萄糖吡喃糖基-(25R)-5α-螺旋甾烷-2α,3β,27-三醇3-O-α-D-鼠李糖吡喃糖基-(1→2)-[α-L-鼠李糖吡喃糖基-(1→4)]-β-D-葡萄糖吡喃糖苷。
