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。
Objective: To study the chemical constituents of Poncirus trifoliata (L.) Raf. Methods: The chloroform fractions of 95% ethanolic extracts of Fructus Aurantii Immaturus were separated by chromatography. The structures of the compounds were determined according to the spectral data and physical and chemical properties. RESULTS: Eight known compounds were isolated and identified as 21α-methylmelianodiol (1), 21β-methylmelianodiol (2), 21α, 25- dimethylmelianodiol (3), 21α-methyltoosen- danpentol Methoxy-7,24,25-trihydroxy-14-apotirucallen-3-one (5), 21S, 23R-epoxy-21β-methoxy-7,24,25-trihydroxy- 6R, 21R, 23R-epoxy-21α-ethoxy-24S, 25-dihy-droxy-apotirucalla-7-en-3-one (7), ichanexic acid (8) Conclusion: Compound 4-8 was isolated from Citrus aurantium for the first time.
