Abstract

Two new lupene-type triterpenoids, 3β,6β-dihydroxylup-20(29)-en-28-oic acid β-glucopyranosyl ester (1) and 2α-acetoxyl-3β,6β-dihydroxylup-20(29)-en-28-oic acid β-glucopyranosyl ester (2), along with 18 known compounds, were isolated from Liquidambar formosana. The structures were elucidated on the basis of spectroscopic methods, including UV, IR, ESIMS, 1D- and 2D-NMR experiments, as well as by comparison of the spectral data with those of related compounds.

摘要

从枫香树中分离得到了两种新的羽扇豆烷型三萜类化合物，3β,6β-二羟基羽扇-20(29)-烯-28-酸β-吡喃葡萄糖苷酯（1）和 2α-乙酰氧基-3β,6β-二羟基羽扇-20(29)-烯-28-酸β-吡喃葡萄糖苷酯（2），以及 18 种已知化合物。这些化合物的结构是基于光谱方法，包括 UV、IR、ESIMS、1D 和 2D-NMR 实验，并通过与相关化合物的光谱数据进行比较来阐明的。
