Abstract

Objective:To investigate the chemical constituents of the essential oil from the herb of Cymbopogon citratus lemongrass and provide useful information for the resonable utilization of lemongrass in Hainan.Method:The essential oil were extracted by water steam distillation,then analyzed by GC-MS and the irrelative contents were calculated by area normalization method.Result:Thirty-three peaks were separated by GC and 30 compounds were identified.The main constituents of the oil were geranial(25.36%),neral(19.76%),geraniol(12.39%),geranyl acetate(4.06%) and β-myrcene(3.48%).Conclusion:The main constituents of the essential oil from lemongrass in Hainan were monoterpenes and their oxygenated derivatives,which were approximately the same as those grown in other parts despite the small difference in contents.
