川楝素是从川楝树皮中提出的驱蛔活性成分,分子式为C30H38O11.含有二个乙酰氧基;三个游离羟基,其中一个与双键有烯丙醇关系;一个羰基处于乙酰氧基的邻位;还有β-单取代呋喃环和1,2环氧基等基团.为一呋喃三萜.通过化学反应及光谱分析,初步确定它的化学结构及其立体构型如Ⅰ式所示.

Chuanliansu (Ⅰ),CaogasW v isolated from the bark of Melia toosendan S: et Z., is an active anthelmintic against ascaris.The NMR spectrum of chuanliansu (Ⅰ) showed three quarternary C-methyl groups and two acetoxyl groups.Acetylation of Ⅰ with acetic anhydride and pyridine under forcing conditions yielded acetylchuanliansu (Ⅱ),C30H44O14 with a molecular weight of 700 as shown by mass spectrometry.
