泽泻化学成分的研究

THE CONSTITUENTS FROM THE RHIZOMA OF ALTSMA ORIENTALIS (SAM) JUZEP.

从泽泻（Alisma orientalis(Sam)Juzep）块茎中分离出12个化合物，经理化性质和波谱分析，分别鉴定为：β-谷甾醇3-O-硬脂酸酯（β-sistosterol-3-O-stearate,1）,正二十三烷（tricosane,2）,β-俗甾醇（β-sitosterol,5）,硬脂酸（stearic acid,6）1-硬脂酸甘油酯（glyeryl 1-stearate,7）,胡萝卜甙6′-O-硬脂酸酯（daucosterol-6′-O-stearate,8）,泽泻醇B单醋酸酯（alisol B monoacetate,9）,大黄素（emodin,10）,泽泻醇C单醋酸酯（alisol C monoacetate,11）,环氧泽泻烯（alismoxide,12）.化合物1，2，5，6，7和10为首次由该植物中获得，化合物12首次以结晶形式获得，化合物3和4的鉴定仍在进行。

Twelve compounds were isolated from 95% EtOH extracts of the rhizoma of Alisma orien-talis. On the basis of chemical and spectropic analyses,ten of them were identified as β-sitosterol-3-O-stearate (1) , tricosane (2), β-sitosterol (5),stearic acid ( 6) , glycerlyl-1 -stearate ( 7 ) , daucosterol-6' -O-stearate (8) , alisol B monoacetate ( 9 ) ,emodin (10), alismol C monoacetate (11), alismoxide (12) respectively. Compounds 1,2,5,6,7 and 10 were isolated from A. Orientalis for the first time. Studies of the chemical structures of the other two compounds (3 and 5) are in progress.
