从胀果甘草（ＧｌｙｃｙｒｒｈｉｚａｉｎｆｌａｔａＢａｔ．）根的１０％乙醇浸出物中分得七个新三萜皂甙。依理化性质及波谱分析，其中二个的结构分别鉴定为：甘草次酸－３－Ｏ－β－Ｄ－６″－乙基－吡喃葡萄糖醛酸基－（１→２）－β－Ｄ－６′－正丁基吡喃葡萄糖醛酸甙（１）和甘草次酸－３－Ｏ－β－Ｄ－６″－正丁基－吡喃葡萄糖醛酸基－（１→２）－β－Ｄ－６′－乙基－吡喃葡萄糖醛酸甙（２）．分别命名为胀果皂甙Ⅱ和Ⅵ。
Seven new triterpenoid saponins were fractionated from 10% ethanol extract from the root of Glycyrrhiza bravis Bat. According to the physicochemical properties and spectral analysis, the structures of the two were identified as glycyrrhetinic acid -3-O-β-D-6 “-ethyl-glucopyranosyl- (1 → 2) -β-D (1) and glycyrrhetinic acid-3-O-β-D-6 ”-n-butyl-glucopyranonoyl- (1 → 2) -β -D-6’-ethyl-glucopyranoside (2). They were named as cypress Ⅱ and Ⅵ.
