THE CHEMICAL COMPONENTS OF THE ESSENTIAL OIL FROM MURRA YA EUCHRESTIFOLIA HAYATA

The essential oil from the branches and leaves of Murraya euchrestifolia Hayata was examined by GC, fractional distillation, column chromatography and GC/MS. Two main components were isolated from the essential oil by using fractional distillation and column chromatography on silica ogel and were identified as limonene (56.10%) and perillaldehyde (34.10%) respectively by IR, NMR and MS spectra. Seven other components were isolated in small amounts and identified as n-propyl-benzene, aromadendrene, elemol, 1-keto-4-hydroxy-decalin, 1-cycloheptyl-1-methyl-ethanol, myrtenal and eicosane.In addition, another seven compounds in this essential oil were identified as α-pinene, camphene, β-pinene, pulegone, perillylalcohol, dihydrocarveyl acetate and cis-carveyl acetate.
