摘要
目的:对三桠苦的化学成分进行研究。方法:采用多种柱层析方法进行分离纯化,通过波谱解析和理化性质进行化学结构鉴定。结果:从三桠苦的石油醚、氯仿和乙酸乙酯部位分离得到7个化合物,分别鉴定为:正十六酸十八烷基酯(Ⅰ)、β-谷甾醇(Ⅱ)、棕榈酸(Ⅲ)、3,5,3′-三羟基-8,4′-二甲氧基-7-异戊烯氧基黄酮(Ⅳ)、胡萝卜苷(Ⅴ)、水杨酸(VI)和山萘酚-3-O-α-D-阿拉伯吡喃糖苷(Ⅶ)。结论:化合物Ⅶ为首次从蜜茱萸属中分离得到,化合物Ⅴ和VI为首次从该植物中分离得到。
Objective：To study the chemical constituents from Melicope ptelefolia.Methods：Several chromatographic methods were applied to isolate and purify compounds.Their structures were identified on the basis of physicochemical properties and spectroscopic data.Results：Seven compounds were isolated and elucidated as n-octadecanyl palmitate（Ⅰ）,β-sitosterol（Ⅱ）,palmitic acid（Ⅲ）,3,5,3′-trihydroxy-8,4′-dimethoxy-7-（3-methylbut-2-enyloxy）flavone（Ⅳ）,daucosterol（Ⅴ）,salylic acid（Ⅵ）,kaempferol-3-O-α-D-arabinpyranoside（Ⅶ）.Conclusion： Compound Ⅶ is isolated from the genus for the first time,Compounds Ⅴ and Ⅵ are isolated from Melicope ptelefolia for the first time.
