Analysis of Chemical Composition of Volatile Oil in Cinnamomum camphora Leaves and Branches by GC-MS

In this paper,volatile oil from the Cinnamomum camphora leaves and branches were obtained by steam distillation.And the yield of their volatile oils were 1.55% and 0.336% respectively.The two essential oils were analyzed by gas chromatography-mass spectrometry and the identified components were compared.They have the same main compositions,but different in relative mass.30 compositions were identified,amounting to 94.45% and 89.73% of the total area of the peaks respectively.Terpene is the major chemical constituent in the volatile oil.
