Abstract

A phytochemical study was carried out on , and obtained a novel ursane-type triterpene saponin, i.e., 3-epi-ursolic acid 3--palmitoyl 28--α-L-arabinofuranosyl ester (), named ajugoside. Its structure and relative configuration were identified mainly by spectroscopic methods including 1D- and 2D-NMR techniques as well as HR-MS analysis. This paper described the isolation and structural elucidation of ajugoside () for the first time.

摘要

进行了植物化学研究，从中得到了一种新型的熊果酸型三萜皂苷，即 3-表-乌苏酸 3--棕榈酰 28--α-L-阿拉伯呋喃糖苷酯（），命名为筋骨草苷。主要通过光谱方法，包括 1D- 和 2D-NMR 技术以及高分辨质谱分析，确定了其结构和相对构型。本文首次描述了筋骨草苷（）的分离和结构阐明。
