英文摘要：

turpentine, β-Caryophyllene, dipentene and α-pinene, which are the main components of heavy were analyzed by an Agilent 7890B gas chromatograph equipped with an HP-5 capillary 5 K/min column and flame ionization detector. The temperature program was 363.15 K ,383. 15 K 10 K/rain ,443.15 K. The temperature of injector and detector was 523.15 K and injected volume of liquid sample was 0. 2 μL. High purity nitrogen was used as carrier gas. The injection was performed in split mode with split ratio 50 ： 1. Components of samples were quantitative analyzed by calibration area normalization method on GC. The calibration factors of β-caryophyllene and α-pinene relative to the reference substance dipentene were determined. The accuracy and recovery of calibration area normalization method were determined. The quantitative methods of area correction normalization and area normalization were compared. The results showed that the relative mass correction factors of β-caryophyllene and α-pinene with dipentene as reference substance were 1. 001 2 and 0. 989 9, respectively. The relative standard deviation of β-caryophyllene, dipentene and α-pinene were less than 1.09% and the recoveries of standard addition were in range of 99. 55% to 100. 25%. The maximum relative deviation of calibration area normalization method and area normalization method was 0. 57% and 1.10% , respectively.
