Abstract

Six steroidal glycosides (1-6) were isolated from the aerial parts of Tribulus alatus Del. (Zygophyllaceae), together with one known cholestane, one spirostane, and six flavonol glycosides. Among them, 1 and 2 possess a furostane-type aglycone, 3 and 6 a cholestane structure, and 4 and 5 a spirostane skeleton. Their structural elucidation was accomplished by extensive spectroscopic methods including 1D ((1)H, (13)C, (13)C DEPT, TOCSY, ROESY) and 2D NMR experiments (DQF-COSY, HSQC, HMBC) as well as ESI-MS analysis.

摘要

从刺蒺藜（蒺藜科）地上部分分离得到6个甾体苷（1 - 6），以及1个已知的胆甾烷、1个螺甾烷和6个黄酮醇苷。其中，1和2具有呋甾烷型苷元，3和6具有胆甾烷结构，4和5具有螺甾烷骨架。通过广泛的光谱方法进行结构解析，包括一维（¹H、¹³C、¹³C DEPT、TOCSY、ROESY）和二维核磁共振实验（DQF - COSY、HSQC、HMBC）以及电喷雾电离质谱分析。
