In order to investigate the optimal extraction process of Cinnamomum camphora essential oil by steam distillation under laboratory conditions, several factors are investigated by single factor experiments. The results show that the extraction yield of essential oil of the C. camphora leaves is higher than that of branches. The effect of over-water distillation method is better than that of in-water distillation. The optimal distillation power is 600 W, the optimal distillation time is 40 min, and the appropriate post-harvest storage time is less than 48 h. The extraction yield of essential oil under these conditions is 1.42%. The chemical composition of C. camphora essential oil is analyzed by gas chromatograph-mass spectrometer. Six compounds are identified, which account for 94.56% of the total peak area, the main component is linalool, it accounts for 89.58% of the total peak area. The antifungal activities of C. camphora essential oil against six plant pathogenic fungi are tested through determining the growth rate of fungal hyphae. The results show that C. camphora essential oil exhibits good antifungal activity against Rhizoctonia solani, when the testing mass concentration of C. camphora essential oil are 500, 250 and 125 mg/L, the inhibition rates are 100%, 90.88% and 67.94%, respectively.
