白花鬼针草化学成分研究

Chemical Constituents in Whole Herb of Bidens pilosa var.radiata

目的:研究白花鬼针草化学成分。方法:利用硅胶柱色谱对白花鬼针草的化学成分进行分离和纯化,采用EI-MS、1H-NMR、13C-NMR等波谱方法结合理化性质鉴定化合物结构。结果:从白花鬼针草中分离鉴定了10个化合物,分别为:木栓酮(1)、正十三烷(2)、木栓醇(3)、β-谷甾醇(4)、21a-羟基木栓烷-3-酮(5)、豆甾醇(6)、羽扇豆醇(7)、豆甾醇-3-O-β-D-葡萄糖苷(8)、二十烷酸(9)和木栓烷-3β-醇-27-酸(10)。结论:10个化合物均为首次从该植物中分离得到。

Objective：To study the chemical constituents of Bidens pilosa var.radiata.Methods：The constituents were separated and purified with silica gel column,and identified by physicochemical properties and spectral methods.Results：Ten compounds were separated and identified as friedelin（1）,n-tridecane（2）,friedelinol（3）,β-sitosterol（4）,21a-hydroxyfriedelan-3-one（5）,stigmasterol（6）,lupeol（7）,stigmasterol-3-O-β-D-glucopyranoside（8）,eleosanole acid（9）,friedelin-3β-ol-27-oic acid（10）.Conclusion： Ten compounds are isolated from this plant for the first time.
