Abstract

Six new bisdesmosidic saponins 1-6, along with four known triterpenoid saponins were isolated from the aerial parts of Trevesia sundaica (Araliaceae). Their structures were determined by 1H-1H correlation spectroscopy (COSY, TOCSY, ROESY) and 1H-13C heteronuclear correlation (HSQC, HMBC) NMR experiments, FABMS, and chemical data.

摘要

从苏门答腊梭罗树（五加科）的地上部分分离得到6个新的双糖链皂苷1 - 6以及4个已知的三萜皂苷。通过1H-1H相关光谱（COSY、TOCSY、ROESY）和1H-13C异核相关（HSQC、HMBC）核磁共振实验、快原子轰击质谱（FABMS）以及化学数据确定了它们的结构。
