摘 要:目的:对绣球藤的化学成分进行研究。方法:利用硅胶柱色谱、Sephadex LH-20等方法进行分离纯化。根据理化性质和光谱分析进行结构鉴定。结果:从绣球藤乙醇提取物的乙酸乙酯部分中分离得到14个化合物,分别鉴定为:松柏醛(1),咖啡酸(2),pluchoic acid(3),原儿茶醛(4),香草醛(5),3,4-二羟基苯乙醇(6),4-羰基-5-羟基戊酸甲酯(7),4-hydroxydodec-2-enedioic acid(8),(+)-川木香醇F(9),(-)-丁香脂素(10),(+)-guayarol(11),(-)-牛蒡苷(12),(-)-落叶松树脂醇(13),金丝桃苷(14)。结论:这些化合物均为首次从该植物中分离得到。AIM: To study the chemical constituents of Clematis montana Buch. -Ham. ex DC.. METHODS: Aerial part of the plant was extracted by ethanol firstly and then the ethyl acetate part of the ethanol extract was isolated by different column chromatographic techniques including silica gel and Sephadex LH-20. Structures of these compounds were identified on the basis of spectroscopic analysis. RESULTS: Fourteen compounds were isolated and their structures were determined to be coniferaldehyde (1), caffeic acid (2), pluchoic acid (3), protocatechualdehyde (4), vanillin (5), hydroxytyrosol (6), 4-carbonyl-5-hydroxy methyl valerate (7), 4-hydroxydodec-2-enedioic acid (8), ( +)-dihydrodehydrodiconiferyl alcohol (9) , ( -)-syringaresinol (10), ( +)-guayarol (11), ( -)-arctiin (12), (-)-lariciresinol (13), and hyperin (14). CONCLUSION: All the compounds were obtained from this plant for the first time.
