Abstract: [Objective] The aim of the study was to analyze and compare the chemical components of volatile oils from the wood of Cinnamomum camphora and Phoebe zhennan, and to provide reference and basis for chemical identification of C. camphora and P. zhennan. [Methods] Ultrasound-assisted petroleum n-hexane/ethanol two-phase solvent extraction was used to extract the essential oil from the wood of C. camphora and P. zhennan. Gas chromatography mass spectrometry(GC-MS) was used to analyze the chemical components of volatile oils. [Results] Thirty-seven and twenty-one kinds of chemical constituents in the essential oils were identified, respectively, from the wood of C. camphora and P. zhennan, accounting for 62.214% and 33.365% of the total. The main components of C. camphora were 3-Cyclohexene-1-methanol, . alpha., . alpha. 4-trimethyl-(7.311%), Eucalyptol(6.850%), Bicyclo[2.2.1]heptan-2-one, 1, 7, 7-trimethyl-, (1R)-(4.674%), Phenol, 2, 4-bis(1, 1-dimethylethyl)-(5.367%) and so on; The main components of P. zhennan were Agarospirol(7.989%), Phenol, 2, 4-bis(1, 1-dimethylethyl)-(3.016%), Bicyclo[3.1.1]hept-3-en-2-one, 6, 6-trimethyl-(2.999%), 2-Naphthalenemethanol, decahydro-.alpha.,.alpha.,4a-trimethyl-8-methylene-,[2R-(2.alpha.,4a.alpha.,8a.beta.)]-(2.331%) and so on;[Conclusion] There are eleven common components in the wood of C. camphora and P. zhennan but there are obvious differences in the principal component between two species. It can be used as an auxiliary means of identification the wood of C. camphora and P. zhennan.
