【摘要】 目的:对荨麻科艾麻属珠芽艾麻药材进行化学成分研究。方法:经70%乙醇回流提取,通过硅胶柱层析等技术,进行分离纯化,结合理化性质及各种波谱数据分析鉴定其化学结构。结果:从珠芽艾麻的根中分离并鉴定了6个化合物,分别是:β-谷甾醇(1)、β-胡萝卜苷(2)2、2,’-oxy-bis(1-phenylethanol)(3)、1-(2-phenylcarbonyloxy ac-etyl)benzene(4)、亚油酸甲酯(5)和14,-二苯基-14,-丁二酮(6)。结论:所有化合物均为首次从该植物中分离得到,其中化合物3和4为首次报道的天然产物。更多还原

【Abstract】 Objective:To study the chemical constituents of Laportea bulbifera.Methods:70% EtOH was used for constituent extraction,silica gel column chromatography for constituent seperation,physical and chemical properties together with spectroscopic methods for chemical structure identification.Results:six compounds were obtained from root of L.bulbifera.Their chemical structures were elucidated as β-sitosterol(1),β-daucosterol(2),2,2′-oxy-bis(1-phenylethanol(3),1-(2-phenylcarbonyloxy acetyl)benzene(4),methyl linoleate(5),1,4-diphenyl-1,4-butanedione(6).Conclusion:All compounds are isolated from L.bulbifera and among compounds 3 and 4 are reported as natural products for the first time.更多还原
