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 content sinessential 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 25components 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 essentialoil of C. hamatulus (NeesexHook. etArn.) 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 essentialoil of C. caesius (Nees ex Hook.et Arn.)Stapfh as 28components, 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 indifferent Cymbopogon species or in the same species from different localities are various. Cymbopogon resources should be exploited and utilized according to practical applications.
