木豆叶的化学成分研究

Study on Chemical Constituents from Leaves of Cajanus cajan

目的:研究木豆叶的化学成分。方法:采用硅胶柱色谱、Sephadex LH-20凝胶色谱及RP-18柱色谱进行分离纯化,并运用波谱数据对所分离得到的化合物进行结构鉴定。结果:从木豆叶中分离得到11个化合物,经波谱解析分别鉴定为:水杨酸(1)、儿茶酚(2)、尿嘧啶(3)、印度黄檀苷(4)、染料木苷(5)、牡荆苷(6)、木犀草素(7)、芒柄花苷(8)、染料木素(9)、β-谷甾醇(10)、豆甾醇(11)。结论:其中,化合物2~4、8为首次从该植物中分离得到。

Objective： To study the chemical constituents from leaves of Cajanus cajan.Methods： The constituents were separated by column chromatography and their structures were elucidated by spectroscophic analysis.Results： Eleven compounds were isolated from the leaves of Cajanus cajan and identified as salicylic acid（1）,catechol（2）,uracil（3）,sissotorin（4）,genistin（5）,vitexin（6）,luteolin（7）,ononin（8）,genistein（9）,β-sitosterol（10）,stigmasterol（11）.Conclusion： Compounds 2 ~ 4,8 are obtained from this plant for the first time.
