Abstract
A new dammarane-type pseudojujubogenin glycoside, bacopasaponin D, has been isolated from the reputed Indian medicinal plant Bacopa monniera and defined as 3-O-[alpha-L-arabinofuranosyl(I-->2)beta-D-glucopyranosyl]pseudojujub ogenin by spectroscopic methods and some chemical transformations. The 13C signals of the saponin were assigned by DEPT, 1H-1H COSY and HSQC techniques.
摘要
一种新的达玛烷型假酸枣皂苷元糖苷——积雪草皂苷D，已从著名的印度药用植物积雪草中分离出来，并通过光谱方法和一些化学转化确定其结构为3-O-[α-L-阿拉伯呋喃糖基（1→2）β-D-吡喃葡萄糖基]假酸枣皂苷元。该皂苷的¹³C信号通过DEPT、¹H-¹H COSY和HSQC技术进行了归属。
