Abstract:The volatile oil of Abies nephrolepis Maxim leaves growing in Changbai Moutain region was analyzed by OV-1 Capillary column (25×0.25)GC/MS/DS and found to contain 46 chemical constituents, 22 of them which make up 96.8% of the total oil were identified. The major components are α-pinene (15.944%), camphene (20.329%), limonene (29.709%), bornyl acetate (17.083%), etc. Six components from the oil were isolated by N2 protected vectification under vacuum, preparative circle thin-layer chromatography and column chromatography. Limonene, borneol, bornyl acetate and α–bisabolol were idetified by IR and MS.
