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%).Read More
