Abstract

Fifteen new bidesmosidic triterpenoid saponins (1-15) were isolated from a methanol extract of the leaves of Mimusops laurifolia. Their structures were established using one- and two-dimensional NMR spectroscopy and mass spectrometry and determined to be bidesmosides of protobassic acid (2-4, 11, 12, and 15) and of 16alpha-hydroxyprotobassic acid (1, 5-10, 13, and 14).

摘要

从月桂叶密花树的甲醇提取物中分离出15种新的双糖基三萜皂苷（1-15）。利用一维和二维核磁共振光谱以及质谱确定了它们的结构，其结构为原巴西酸（2-4、11、12和15）以及16α-羟基原巴西酸（1、5-10、13和14）的双糖苷。
