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.
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。
