Abstract

The methanol extracted leaves of Asparagus curillus furnished two oligospirostanosides (curillins G and H) and two oligofurostanosides (curillosides G and H) which were characterized as 3-O-[beta-D-glucopyranosyl(1-->4)-beta-D-glucopyranosyl]-(25S)-5 beta- spirostan-3 beta-ol; 3-O-[(alpha-L-rhamnopyranosyl(1-->2))(-beta-D-glucopyranosyl(1--> 4))-beta-D-glucopyranosyl]-(25S)-5 beta, spirostan-,3 beta-ol; 3-O-[(alpha-L-rhamnopyranosyl(1-->2)) (beta-D-glucopyranosyl(1-->4))-beta-D-glucopyranosyl]-26-O-[beta-D- glucopyranosyl]-22 alpha-methoxy-(25S)-5 beta-furostan-3 beta,26-diol and 3-O-[(alpha-L-rhamnopyranosyl(1-->2))-(beta-D-glucopyranosyl(1-->4))- beta-D-glucopyranosyl]-26-O-[beta-D-glucopyranosyl]-(25S)-5 beta-furostan-3 beta,22 alpha,26-triol, respectively.

摘要

曲枝天门冬甲醇提取物的叶子中含有两种寡螺甾烷苷（曲菌素G和H）和两种寡呋甾烷苷（曲菌素苷G和H），它们分别被鉴定为3-O-[β-D-吡喃葡萄糖基(1→4)-β-D-吡喃葡萄糖基]-(25S)-5β-螺甾烷-3β-醇；3-O-[（α-L-吡喃鼠李糖基(1→2))(-β-D-吡喃葡萄糖基(1→4))-β-D-吡喃葡萄糖基]-(25S)-5β,螺甾烷-,3β-醇；3-O-[（α-L-吡喃鼠李糖基(1→2))(β-D-吡喃葡萄糖基(1→4))-β-D-吡喃葡萄糖基]-26-O-[β-D-吡喃葡萄糖基]-22α-甲氧基-(25S)-5β-呋甾烷-3β,26-二醇和3-O-[（α-L-吡喃鼠李糖基(1→2))-(β-D-吡喃葡萄糖基(1→4))-β-D-吡喃葡萄糖基]-26-O-[β-D-吡喃葡萄糖基]-(25S)-5β-呋甾烷-3β,22α,26-三醇。
