【摘要】 目的:研究红绒毛羊蹄甲Bauhinia aurea的化学成分。方法:应用各种色谱技术进行分离纯化,用MS和NMR分析鉴定化合物结构。结果:从90%乙醇提取物中分离得到12个化合物,分别为:3,4-二羟基苯甲酸(1),4-羟基苯甲酸(2),3-羟基-4-甲氧基苯甲酸(3),4-羟基-3-甲氧基苯甲酸(4),没食子酸(5),没食子酸甲酯(6),没食子酸乙酯(7),羽扇豆-3-醇(8),羽扇豆-3-酮(9),豆甾-4-烯-3-酮(10),β-谷甾醇(11)和胡萝卜苷(12)。结论:除化合物5,8,11和12外,其余化合物均属首次从该属植物中发现。更多还原

【Abstract】 Objective: To study the chemical constituents of Bauhinia aurea.Method: The compounds were isolated with column chromatography.The structures were determined by MS and NMR spectroscopic techniques.Result: Nine aromatic acid derivatives,two triterpenes and three steroids were isolated from the 90% ethanolic extract and their structures were identified as 3,4-dihydroxybenzoic acid(1),() 4-hydroxybenzoic acid(2),() 3-hydroxy-4-methoxy-benzoic acid(3),() 4-hydroxy-3-methoxybenzoic acid(4),() gallic acid(5),() methyl gallate(6),() ethyl gallate(7),() lupeol(8),() lupenone(9),() stigmast-4-en-3-one(10),()β-sitosterol(11)() and daucosterol(12).Conclusion: This is the first report of chemical constituents from B.aurea.Compounds were isolated from this genus for the first time,except 5,8,11() and 12.更多还原
