摘要
目的研究三桠苦Melicope pteleifolia的化学成分。方法三桠苦用80%乙醇渗漉提取,提取物用色谱技术分离,采用波谱技术(EI-MS、1H-NMR、13C-NMR等)和化学方法进行结构鉴定。结果从三桠苦乙醇提取物的石油醚部位和醋酸乙酯部位分离出4个化合物,分别鉴定为3,5,3′-三羟基-4′-甲氧基-7-异戊烯氧基黄酮(1)、3,7-二甲氧基山柰酚(2)、香草酸(3)、β-谷甾醇(4)。结论化合物1是新化合物,命名为三桠苦素C,化合物2、3为首次从该植物中分离得到。
Objective To study the constituents of Melicope pteleifolia.Methods Plant material was percolated with 80% EtOH.Compounds were separated with chromatography technology and their structures were elucidated by spectral analysis（EI-MS,1H-NMR,and 13C-NMR） and chemical evidence.Results Four compounds were isolated from petroleum ether and ethyl acetate soluble fractions.Their structures were identified as：3,5,3′-trihydroxy-4′-methoxy-7-（3-methylbut-2-enyloxy） flavone（1）,3,7-methoxyl kaempferol（2）,vanillic acid（3）,and β-sitosterol（4）.Conclusion Compound 1 is a new compound named pteleifolosin C.Compounds 2 and 3 are isolated from this plant for the first time.
