Abstract

In addition to solamargine, two new steroid alkaloid glycosides, anguivine and isoanguivine, have been isolated from the roots of Solanum anguivi, the structures of which have been elucidated as (25R)-3 beta-[O-alpha-L-rhamnopyranosyl-(1-->2)-O-[beta-D- xylopyranosyl-(1-->3)]-beta-D-glucopyranosyloxy]-22 alpha N-spirosol-5-ene and (25R)-3 beta-[O-alpha-L-rhamnopyranosyl-(1-->2)-O-[beta-D-xylopyranosyl- (1-->3)-beta-D-galactopyranosyloxy]-22 alpha N-spirosol-5-ene.

摘要

除了茄解碱之外，还从刺茄的根部分离出了两种新的甾体生物碱苷，即刺茄碱和异刺茄碱，它们的结构已被阐明为(25R)-3β-[O-α-L-鼠李吡喃糖基-(1→2)-O-[β-D-木吡喃糖基-(1→3)]-β-D-葡萄糖吡喃糖氧基]-22α-N-螺旋甾-5-烯和(25R)-3β-[O-α-L-鼠李吡喃糖基-(1→2)-O-[β-D-木吡喃糖基-(1→3)-β-D-半乳糖吡喃糖氧基]-22α-N-螺旋甾-5-烯。
