绿衣枳实的化学成分(英文)

Chemical Constituents from the Fruits of Poncirus trifoliata

目的:研究绿衣枳实(Poncirus trifoliata(L.)Raf.)的化学成分。方法:对绿衣枳实95%乙醇提取物的氯仿部分进行色谱分离,根据光谱数据和理化性质确定各化合物的结构。结果:分离得到8个已知化合物,分别为:21α-methylmelianodiol(1),21β-methylmelianodiol(2),21α,25-dimethylmelianodiol(3),21α-methyltoosen-danpentol(4),21R,23R-epoxy-21α-methoxy-7,24,25-trihydroxy-14-apotirucallen-3-one(5),21S,23R-epoxy-21β-methoxy-7,24,25-trihydroxy-14-apotirucallen-3-one(6),21R,23R-epoxy-21α-ethoxy-24S,25-dihy-droxy-apotirucalla-7-en-3-one(7),ichanexic acid(8).。结论:化合物4-8为首次从枳属中分得。

AIM：To investigate the chemical constituents from the fruits of Poncirus trifoliata（L.）Raf.. METHODS：The constituents of CHCl3-soluble portions in the 95%ethanol extract were isolated and purified by various chromatographic methods.Their structures were identified by the physicochemical characteristic and spectral data. RESULTS：Eight known compounds were isolated and identified as 21α-methylmelianodiol（1）,21β-methylmelianodiol（2）,21α,25-dimethylmelianodiol（3）,21α-methyltoosendanpentol（4）,21R,23R-epoxy-21α-methoxy-7,24,25-trihydroxy-14-apotirucallen-3-one（5）,21S,23R-epoxy-21β-methoxy-7,24,25-trihydroxy-14-apotirucallen-3-one（6）,21R, 23R-epoxy-21α-ethoxy,24S,25-dihydroxy-apotirucalla-7-en-3-one（7）,ichanexic acid（8）.CONCLUSION：Compounds（4-8）were isolated from the Poncirus genus for the first time.
