Abstract

A new acylated flavonoid, 3-O-rhamnocitrin-6-O-benzoyl-β-D-glucopyranoside (1), together with five known flavonoids, rhamnocitrin (2), pratensein (3), (3R)-7,3'-dihydroxy-2',4'-dimethoxyisoflavan (4), (3R)-7,2'-dihydroxy-3',4'-dimethoxyisoflavan (5) and isoliquiritigenin (6), was isolated from Oxytropis ochrocephala Bunge. The structural elucidation of the isolated compounds was primarily based on HRESIMS, IR and 1-D- and 2-D-NMR analyses.

摘要

从黄花棘豆中分离得到一个新的酰化黄酮类化合物，3-O-鼠李糖基-6-O-苯甲酰基-β-D-吡喃葡萄糖苷（1），以及五个已知的黄酮类化合物，鼠李糖苷（2）、草甸黄芩素（3）、（3R）-7,3'-二羟基-2',4'-二甲氧基异黄酮（4）、（3R）-7,2'-二羟基-3',4'-二甲氧基异黄酮（5）和甘草素（6）。这些化合物的结构鉴定主要基于高分辨质谱（HRESIMS）、红外光谱（IR）和一维（1D）及二维（2D）核磁共振分析。
