Abstract

Solamargine, solasonine, N-hydroxyrobustine and a new glycoalkaloid, N-hydroxysolamargine, has been isolated from the leaves of Solanum robustum, the structure of which has been elucidated as (25R)-3beta-{O-alpha-L-rhamnopyranosyl-(1-->2)-O-[alpha-L- rhamnopyranosyl- (1-->4)]-beta-D-glucopyranosyloxy}-22alphaN- spirosol-5-en-N-ol.

摘要

从刺茄叶片中分离得到了澳洲茄碱、澳洲茄边碱、N-羟基蜀羊泉碱和一种新的糖苷生物碱N-羟基澳洲茄碱，其结构已被阐明为(25R)-3β-{O-α-L-鼠李吡喃糖基-(1→2)-O-[α-L-鼠李吡喃糖基-(1→4)]-β-D-葡萄糖吡喃糖氧基}-22αN-螺旋甾-5-烯-N-醇。
