Abstract

Four new phenolic glycosides, beta-apiofuranosyl-(1-->2)-beta-glucopyranosides (1-4), along with the cycloartane triterpenes 20(R),25-epoxy-3beta,6alpha,16beta,24alpha-tetrahydroxycycloartane (5) and 20(R),24(S)-epoxy-3beta,6alpha,25-trihydroxycycloartan-16-one (6) were isolated from roots of Astragalus zahlbruckneri. The structure elucidation of all compounds was based on their (1)H and (13)C NMR spectral data including 1D-TOCSY, DQF-COSY, HSQC, and HMBC experiments.

摘要

从紫花黄芪的根中分离出四种新的酚苷，即β-芹菜呋喃糖基-(1→2)-β-吡喃葡萄糖苷（1-4），以及环阿尔廷烷三萜20(R),25-环氧-3β,6α,16β,24α-四羟基环阿尔廷烷（5）和20(R),24(S)-环氧-3β,6α,25-三羟基环阿尔廷-16-酮（6）。所有化合物的结构解析均基于它们的¹H和¹³C NMR光谱数据，包括一维全相关谱（1D-TOCSY）、双量子滤波相关谱（DQF-COSY）、异核单量子相干谱（HSQC）和异核多键相关谱（HMBC）实验。
