Abstract: Essential oil from stem and leaf(samples of mixed leaves and old leaves)of linalool-type Cinnamomum camphora (Linn.) Presl was extracted respectively by steam distillation method. The essential oils were analyzed with gas chromatography and GC-MS-DS quantitatively and qualitatively. The results show that content and chemical compositions of essential oil from stem and leaf of linalool-type C.camphora have great difference. The mass fraction of essential oil in leaves (1.39%) is higher than in stem (0.54%); The mass fraction of linalool in leaf essential oil (89.59%) is higher than in stem (74.49%); The mass fraction of camphor in leaf essential oil (0.61%) is lower than in stem (4.34%); The quality of leaf essential oil collected in October (linalool 92.69%, camphor 0.40%) is superior to leaves collected in July (linalool 86.49%, camphor 0.82%).

Key words: Cinnamomum camphora(Linn.)Presl, essential oil, linalool, camphor, component analysis
