From the herb of Luffa acutangula ROXB. (Cucurbitaceae), seven oleanane-type triterpene saponins, acutosides A--G, were isolated and their structures were determined. Acutoside A is oleanolic acid 3-O-beta-D-glucopyranosyl-(1----2)-beta-D-glucopyranoside. Acutosides B, D, E, F and G have a common prosapogenin structure, acutoside A, and only differ in the structures of the ester-linked sugar moieties. Acutoside B is a 28-O-[O-beta-D-xylopyranosyl-(1----4)-O-alpha-L-rhamnopyranosyl-(1----2) -alpha-L-arabinopyranosyl] ester, D is a 28-O-[O-beta-D-xylopyranosyl-(1----3)-O-beta-D-xylopyranosyl-(1----4)-O- alpha-L-rhamnopyranosyl-(1----2)-alpha-L-arabinopyranosyl] ester, E is a 28-O-[O-alpha-L-arabinopyranosyl-(1----3)-O-beta-D-xylopyranosyl-( 1----4)-O-alpha-L-rhamnopyranosyl-(1----2)-alpha-L-arabinopyranosyl] ester, F is a 28-O-[O-beta-D-xylopyranosyl-(1----3)-[O-beta-D-xylopyranosyl-(1----4)-O -alpha-L-rhamnopyranosyl-(1----2)-alpha-L-arabinopyranosyl] ester, and G is a 28-O-beta-D-xylopyranosyl-(1----3)-[O-alpha-L-arabinopyranosyl-(1- ---3)-O-beta-D-xylopyranosyl-(1----4)]-O-alpha-L- rhamnopyranosyl-(1----2)-alpha-L-arabinopyranosyl] ester. Acutoside C is a machaelinic acid (=21 beta-hydroxyoleanolic acid) saponin having the same sugar moiety as that of acutoside B.
从棱角丝瓜（葫芦科）的全草中，分离得到7种齐墩果烷型三萜皂苷，即丝瓜皂苷A - G，并确定了它们的结构。丝瓜皂苷A是齐墩果酸3 - O - β - D - 吡喃葡萄糖基 - (1→2) - β - D - 吡喃葡萄糖苷。丝瓜皂苷B、D、E、F和G具有共同的前皂苷元结构丝瓜皂苷A，只是在酯键连接的糖部分结构上有所不同。丝瓜皂苷B是28 - O - [O - β - D - 吡喃木糖基 - (1→4) - O - α - L - 吡喃鼠李糖基 - (1→2) - α - L - 阿拉伯吡喃糖基]酯，D是28 - O - [O - β - D - 吡喃木糖基 - (1→3) - O - β - D - 吡喃木糖基 - (1→4) - O - α - L - 吡喃鼠李糖基 - (1→2) - α - L - 阿拉伯吡喃糖基]酯，E是28 - O - [O - α - L - 阿拉伯吡喃糖基 - (1→3) - O - β - D - 吡喃木糖基 - (1→4) - O - α - L - 吡喃鼠李糖基 - (1→2) - α - L - 阿拉伯吡喃糖基]酯，F是28 - O - [O - β - D - 吡喃木糖基 - (1→3) - [O - β - D - 吡喃木糖基 - (1→4) - O - α - L - 吡喃鼠李糖基 - (1→2) - α - L - 阿拉伯吡喃糖基]酯，G是28 - O - β - D - 吡喃木糖基 - (1→3) - [O - α - L - 阿拉伯吡喃糖基 - (1→3) - O - β - D - 吡喃木糖基 - (1→4)] - O - α - L - 吡喃鼠李糖基 - (1→2) - α - L - 阿拉伯吡喃糖基]酯。丝瓜皂苷C是一种马钱子酸（=21β - 羟基齐墩果酸）皂苷，其糖部分与丝瓜皂苷B相同。
