A new pregnane glycoside has been isolated from the overripe fruits of Cherry tomato (Mini tomato), Lycopersicon esculentum var. cerasiforme (DUNAL) ALEF. The structure was determined to be 3-O-beta-lycotetraosyl 3beta-hydroxy-5alpha-pregn-16-en-20-one on the basis of spectroscopic analysis. The seasonal variation of the tomato saponin is discussed.
从樱桃番茄（小番茄），即番茄（Lycopersicon esculentum var. cerasiforme (DUNAL) ALEF）的过熟果实中分离出一种新的孕烷糖苷。通过光谱分析确定其结构为3-O-β-番茄四糖基-3β-羟基-5α-孕-16-烯-20-酮。文中还讨论了番茄皂苷的季节变化。
