[Objective ] The aim was to compare volatile oils component of Loropetalum chinense and L. Chnreuse var. Rubruin, and provide basis for development and utilization. [Method] Volatile oils were extracted from three kinds of leaves,including the leaves of L chinense,the green and red leaves of L. Chinense var. Rubrum, with the simultanuous distillation and solvent extraction (SDE) device. They were divided and identified by GC-MS. [Results] The results showed that there were 44,55 and 36 components separated from related leaves,25,21,23 components had been I dentified,which accounted for 74.11% ,83.94% ,76. 88% of the total extraction, respectively. The more abundant components in the extraction were as follows:3-Hexen-l-ol, (Z) - ( 38. 79% , 12. 73% ,30. 47% ), n-Hexadecanoic acid (5. 31% , 17. 47% ,6. 02% ) , Octadecanoic acid (1.99% ,5.03% ,2.55% ) ,Oleic acid (2.63% ,33.31% ,9.13% ). [Conclusion] These components could be used in many fields such as medi cine and health care,spices,food additive and antibiotic insecticide.%[目的]分析比较檵木和红花檵木叶片挥发油的成分,为进一步开发利用积累数据.[方法]采用同时蒸馏萃取提取檵木叶、红花檵木绿叶和红花檵木红叶的挥发性成分,用气相色谱-质谱联用技术对其进行分离鉴定.[结果]在3种叶片中分别分离出44、55、36种成分,分别鉴定出25、21、23种成分,已确定组分分别占总峰面积的74.11％、83.94％、76.88％.含量较多的组分有:顺-3-己烯-1-醇(38.79％、12.73％、30.47％)、棕榈酸(5.31％、17.47％、6.02％)、硬脂酸(1.99％、5.03％、2.55％)油酸(2.63％、33.31％、9.13％).[结论]其主要成分在医药卫生、香料、食品添加剂和抗菌杀虫剂等领域有很好的开发前景.
