摘要 目的:研究博落回果荚的化学成分。方法:采用硅胶柱层析以及制备高效液相色谱法进行分离纯化,并根据波谱学数据鉴定化合物的结构。结果:从博落回果荚的乙醇提取物中分离纯化得到8个生物碱,分别鉴定为:6-氰基二氢血根碱(1)、6-丙酮基二氢血根碱(2)、6-丙酮基二氢白屈菜红碱(3)、白屈菜红碱(4)、二氢白屈菜红碱(5)、13,14-去氢-N-甲基黄连碱(6)、N-甲基氢化小檗碱(7)、小檗碱(8)。结论:其中,化合物1、6为新的天然产物,化合物7为首次在博落回属植物中报道。 Objective:To study the alkaloids from the fruit of Macleaya cordata. Methods:The alkaloids were isolated and purified by silica gel column chromatography and preparative high performance liquid chromatography, and the structures were elucidated based on the spectral data. Results : Eight alkaloids were obtained from the fraction of ethanol extract and identified as 6-cyanodihydrosanguina- rine ( 1 ), 6-acetonyldihydrosanguinarine (2), 6-acetonyldihydrochelerythrine (3), chelerythrine ( 4), dihydrochelerythrine ( 5 ), 13,14-de- hydrogen-N-methyl-coptisine (6), N-methyl-canadine (7) and berberine ( 8 ). Conclusion : Compounds 1 and 6 are new nature products, and compound 7 is isolated from this plant for the first time.
