从番茄 (Lycopersicon esculentum) 的叶和果实中分离出三种新的甾体生物碱苷，番茄苷 A-C，并在结构上阐明为 (23R)-23-乙酰氧基托马替丁、(23S)-23-乙酰氧基索拉杜西丁和 (23S,25S)-23-乙酰氧基-5 的 3-O-β-番茄四苷。 α,22 α N-spirosolan-3 beta-ol。除了这些苷外，叶子和果实还发现含有已知的主要生物碱番茄碱（番茄碱3-O-β-lycotetraoside）和少量的γ-番茄碱（番茄碱3-O-[β-D-吡喃葡萄糖基-(1 --> 4)-β-D-吡喃半乳糖苷]，番茄苷D）。
Three new steroidal alkaloid glycosides, lycoperosides A-C, were isolated from leaves and fruits of tomato, Lycopersicon esculentum, and structurally elucidated as the 3-O-beta-lycotetraosides of (23R)-23-acetoxytomatidine, (23S)-23-acetoxysoladulcidine and (23S,25S)-23-acetoxy-5 alpha,22 alpha N-spirosolan-3 beta-ol. In addition to these glycosides, leaves and fruits were found to contain the known major alkaloid tomatine (tomatidine 3-O-beta-lycotetraoside) and leaves a small amount of gamma-tomatine (tomatidine 3-O-[beta-D-glucopyranosyl-(1 --> 4)-beta-D-galactopyranoside], lycoperoside D).
