延胡索中的生物碱成分

目的:研究延胡索Corydalis yanhusuo块茎60%乙醇提取物的生物碱成分.方法:采用多种色谱学方法进行分离纯化,根据理化性质和波谱数据鉴定化合物的结构.结果:从延胡索块茎60%乙醇提取物的氯仿可溶部分分离得到9个生物碱,分别鉴定为7-醛基脱氢海罂粟碱(1),O-甲基南天竹碱(2),(+)-O-甲基球紫堇碱(3),d-紫堇碱(4),四氢黄连碱(5),8-氧黄连碱(6),巴马亭(7),四氢巴马亭(8)和去氢紫堇碱(9).结论:化合物1为首次从生物样品中获得,首次报道了其核磁数据,化合物3为首次从罂粟科植物中分离得到,化合物6为首次从该植物中分离得到.

Chemical constituents from Corydalis yanhusuo

Objective: To study the chemical constituents from the 60% ethanol extract of Corydalis yanhusuo. Method: The chemical constituents were separated and purified by various chromatographic techniques, and their structures were elucidated by chemical evidence and spectroscopic analysis. Result: Nine alkaloids were obtained and determined as 7-formyldidehydroglaucine (1), nantenine (2), (+)-O-methylbulbocapnine (3), d-corydaline (4), tetrahydrocoptisine (5), 8-oxocoptisine (6), palmatine (7), tetrahydropalmatine (8), and dehydrocorydaline (9), respectively. Conclusion: Compound 1 was obtained from natural products for the first time, and its NMR data were firstly reported. Compound 3 was reported from Papaveraceae for the first time,and compound 6 was firstly reported from Corydalis yanhusuo.
