Abstract

One new triterpenoid, 3beta, 16beta, 23, 28-tetrahydroxy oleana-11, 13(18)-dien-3-O-beta-D-glucopyranosyl(1 --> 3) [beta-D-glucopyranosyl(1 --> 2)]-beta-D-fucopyranoside (1), together with two known flavonoids, were isolated from Stellaria media (L.) Cyr. The structure elucidation of the new compound was primarily based on HREIMS, EIMS, UV, IR, 1D- and 2D-NMR analyses, including COSY, HMQC and HMBC correlations.

摘要

从繁缕（Stellaria media (L.) Cyr.）中分离出一个新的三萜类化合物3β, 16β, 23, 28-四羟基齐墩果-11, 13(18)-二烯-3-O-β-D-吡喃葡萄糖基(1→3)[β-D-吡喃葡萄糖基(1→2)]-β-D-吡喃岩藻糖苷（1）以及两个已知的黄酮类化合物。新化合物的结构解析主要基于高分辨电子轰击质谱（HREIMS）、电子轰击质谱（EIMS）、紫外光谱（UV）、红外光谱（IR）、一维和二维核磁共振（1D-和2D-NMR）分析，包括化学位移相关谱（COSY）、异核多量子相干谱（HMQC）和异核多键相关谱（HMBC）。
