摘要：

Objective To study the constituents in Melicope pteleifolia.Methods Plant material was isolated with 80% EtOH.Compounds were separated with chromatographic methods and their structures were elucidated on the basis of spectral analysis(EI-MS,1H-NMR,and 13C-NMR) and chemical evidence.Results Five compounds were isolated from petrol ether or ethyl acetate soluble fraction.Their structures were identified as 3,5,3'-trihydroxy-4'-methoxy-7-(3-methylbut-2-enyloxy) flavone(pteleifolosin C,1),3,7-dimethoxyl kaempferol(kamatakenin,2),vanillic acid(3),tricosanoic acid tetradecyl ester(4),and β-sitosterol(5),respectively.Conclusion Compound 1 is a new structure named pteleifolosin C.Compounds 2-4 are isolated from this plant for the first time.
