Abstract

Two new rhamnocitrin glycosides (1 and 2) were isolated from the aerial parts of Astragalus vogelii, along with one known rhamnocitrin glycoside (3). Two known flavonol glycosides (4 and 5) and four known flavone derivatives (6-9) were isolated from the aerial parts of Astragalus eremophilus. Their structures were elucidated by extensive spectroscopic methods including 1D- (1H, 13C and TOCSY) and 2D-NMR (DQF-COSY, HSQC, HMBC) experiments, as well as ESIMS analysis.

摘要

从伏氏黄芪地上部分分离得到两种新的鼠李柠檬素糖苷（1和2）以及一种已知的鼠李柠檬素糖苷（3）。从旱生黄芪地上部分分离得到两种已知的黄酮醇糖苷（4和5）和四种已知的黄酮衍生物（6 - 9）。通过包括一维（¹H、¹³C和TOCSY）和二维核磁共振（DQF - COSY、HSQC、HMBC）实验以及电喷雾离子化质谱分析等广泛的光谱方法对它们的结构进行了阐明。
