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。
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 trlterpenes 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,U and 12.
