Abstract

A new triterpenoid saponin, 3-O-[beta-D-galactopyranosyl-(1 --> 3)-O-beta-D-xylopyranosyl-(1 --> 4)-O-alpha-L-rhamnopyranosyl]-oleanolic acid; has been isolated from the seeds of Lactuca scariola. Its structure was determined by various spectral analysis and chemical degradations. This compound shows antimicrobial activity against various bacteria and fungi.

摘要

一种新的三萜皂苷，3 - O - [β - D - 吡喃半乳糖基 - (1→3) - O - β - D - 吡喃木糖基 - (1→4) - O - α - L - 吡喃鼠李糖基] - 齐墩果酸，已从刺莴苣种子中分离得到。其结构通过各种光谱分析和化学降解得以确定。该化合物对多种细菌和真菌显示出抗菌活性。
