Five monodesmosidic serjanic acid saponins and a monodesmosidic spergulagenic acid saponin were isolated from an aqueous extract of the berries of Phytolacca icosandra. A methanol extract of the berries furnished three bidesmosidic serjanic acid glycosides. Their structures were established by spectroscopic (ES-MS, 1H NMR, COSY, HSQC, HMBC, 13C NMR) and chemical methods. The molluscicidal, spermicidal
从 Phytolacca icosandra 浆果的水提取物中分离出五种单链丝氨酸皂苷和一种单链丝木霉酸皂苷。浆果的甲醇提取物提供了三种双糖苷 serjanic 酸苷。它们的结构是通过光谱(ES-MS、1H NMR、COSY、HSQC、HMBC、13C NMR)和化学方法确定的。研究了皂苷的杀软体动物、杀精子和溶血特性。
