Chemical Composition of Fruit of Embelia undulata(Wall.)Mez

[Objectives]To study the chemical constituents of the fruit of Embelia undulata(Wall.)Mez.[Methods]Silica gel column chromatography,gel column chromatography,recrystallization,high-performance preparative liquid chromatography and other modern separation methods and techniques were used to separate and purify the chemical components of the ethyl acetate fraction of the fruit of E.undulata(Wall.)Mez,and based on the physical and chemical properties and spectral data,their structure was identified.[Results]Six compounds were isolated from the fruit of E.undulata(Wall.)Mez,including trimethyl citrate(1),vanillic acid(2),5-hydroxymethylfurfural(3),1,5-dimethyl citrate(4),1,6-dimethyl-5-ethyl citrate(5)and 3,4-dihydroxybenzoic acid(6).[Conclusions]Compounds 1-6 are all isolated from E.undulata(Wall.)Mez for the first time.
