目的对大戟属植物高山大戟Euphorbia stracheyi进行化学成分研究。方法采用硅胶、sephadex LH-20、ODS、MPLC、MCI柱色谱等方法进行分离纯化,根据理化性质及波谱数据鉴定化合物的结构。结果从高山大戟醋酸乙酯部位分离鉴定了9个化合物,分别为槲皮素-3-O-α-阿拉伯糖苷(1)、槲皮素-3-O-α-(2″-没食子酰基)-阿拉伯糖苷(2)、槲皮素-3-O-(2″,3″-二没食子酰基)-β-D-半乳糖苷(3)、3′,5′-二甲氧基-4′,5,7-三羟基黄酮(4)、槲皮素(5)、去氢诃子次酸三甲酯(6)、β-谷甾醇(7)、吐叶醇(8)、没食子酸(9)。结论所有化合物均是首次从该植物中分离得到,化合物1、2、4、6、8均是首次从该属植物中分离得到。 OBJECTIVE To study the chemical constituents of Euphorbia stracheyi from Euphorbia. Methods The compounds were isolated and purified by silica gel, sephadex LH-20, ODS, MPLC and MCI column chromatography. The structures of the compounds were identified by physicochemical properties and spectral data. Results Nine compounds were isolated and identified from Echinacea purpurea, which were quercetin -3-O-α-arabinoside (1), quercetin -3-O- ) - arabinoside (2), quercetin -3-O- (2 “, 3” -di-galloyl) -β-D-galactoside (3), 3 ’, 5’-dimethoxy- 4, 5,7-trihydroxyflavone (4), quercetin (5), mesitylene dehydrogenate (6), β-sitosterol Acid (9) .Conclusion All the compounds were isolated from this plant for the first time. Compounds 1, 2, 4, 6 and 8 were isolated from this genus for the first time.
