摘　　要：利用GC-MS技术分析了广东省3种野生香茅属(Cymbopogon Spreng.)植物叶片精油的化学成分及其相对含量。结果表明,3种植物精油中的化学成分丰富。从橘草〔C.goeringii(Steud.)A.Camus〕精油中鉴定出25种化学成分,主要成分为香叶醇、香茅醛、Z-柠檬醛和E-柠檬醛,相对含量分别为26.56%、23.49%、19.65%和12.78%;从扭鞘香茅〔C.hamatulus(Nees ex Hook.et Arn.)A.Camus〕精油中鉴定出16种化学成分,主要成分为甲基丁香酚、甲基异丁香酚、3,5,3′,5′-四甲基联苯和3,4-二乙基-1,1′-联苯,相对含量分别为19.46%、12.90%、16.88%和8.63%;从青香茅〔C.caesius(Nees ex Hook.et Arn.)Stapf〕精油中鉴定出28种化学成分,主要成分为甲基丁香酚、甲基异丁香酚和藜芦醛,相对含量分别为29.39%、22.25%和6.58%。香茅属植物的精油成分因种类和产地不同而有一定的差异,在实际生产中应根据需要对香茅属植物资源进行合理的开发和利用。Chemical components and their relative contents in essential oil from three wild species of Cymbopogon Spreng.in Guangdong Province were analyzed by GC-MS.The results show that the chemical components are abundant in essential oil of the three species.There are 25 components in the essential oil of C.goeringii（Steud.） A.Camus,with 26.56% geraniol,23.49% citronellal,19.65% Z-citral and 12.78% E-citral as its main components.There are 16 components in the essential oil of C.hamatulus（Nees ex Hook.et Arn.） A.Camus,with 19.46% methyl eugenol,12.90% methyl isoeugenol,16.88% 3,5,3′,5′-tetramethyl biphenyl and 8.63% 3,4-diethyL^-1,1′-biphenyl as its main components.The essential oil of C.caesius（Nees ex Hook.et Arn.）Stapf has 28 components,and its main components are methyl eugenol,methyl isoeugenol and veratraldehyde with the relative contents of 29.39%,22.25% and 6.58%,respectively.It is suggested that chemical components in different Cymbopogon species or in the same species from different localities are various.Cymbopogon resources should be exploited and utilized according to practical applications.
