摘要 目的:研究款冬花的化学成分。方法:采用硅胶柱色谱方法进行分离、纯化,NMR和MS等方法进行结构鉴定。结果:从款冬花的干燥花蕾乙醇提取物中分离鉴定了11个化合物,分别为3,4-O-二咖啡酰基奎宁酸甲酯(1),3,5-O-二咖啡酰基奎宁酸甲酯(2),4,5-O-二咖啡酰基奎宁酸甲酯(3),3,5-O-二咖啡酰基奎宁酸(4),3-O-咖啡酰基奎宁酸甲酯(5),3-O-咖啡酰基奎宁酸(6),金丝桃苷(7),芦丁(8),山柰酚3-O-吡喃葡萄糖苷(9),槲皮素(10)和山柰酚(11)。结论:化合物2-5为首次从款冬属植物中分离得到。 Objective: To study the chemical constituents in the buds of Tussilagofa(ara. Method: The chemical constituents were isolated by various column chromatographic methods and structurally elucidated by NMR and MS evidences. Result: Eleven compounds were obtained and identified as methyl 3, 4-O-dicaffeoylquinate ( 1 ), methyl 3, 5-O-dicaffeoylquinate (2), methyl 4, 5-O-di- caffeoylquinate (3), 3, 5-O-dicaffeoylquinic acid (4), methyl 3-O-caffeoylquinate (5), 3-O-caffeoylquinic acid (6), hyperoside (7), rutin (8), kaempferol 3-O-β-D-glucopyranoside (9), quercetin ( 10), and kaempferol ( 11 ). Conclusion: Compounds 2-5 were isolated from the genus for the first time.
