Objective To establish an accurate and high sensitivity method for determine of volatile components in Gutongtiegao by GC,and compare of volatile components in Gutongtiegao with different matrix.Method GC with Agilent HP-5(30 mm,0.32 mm,0.25 μm)and FID detector was used.The injector temperature was 200 ℃,and the detector temperature was 240 ℃.Temperature programming method was used.Result The linear relationship of camphor in 0.023～5.84 mg/mL,menthol in 0.009～2.20 mg/mL and cinnamaldehyde in 0.004～1.04 mg/mL were good,and the correlation coefficients were greater than 0.999.The standard recovery rate of camphor,menthol and cinnamaldehyde ranged from 96.8％to 104.8％,98.3％to 109.0％,90.5％to 98.4％,respectively.The content of camphor and menthol in Gutongtiegao with thermoplastic rubber matrix was higher than that in Gutongtiegao with traditional rubber matrix.Conclusion The method is accurate,sensitive and reproducible,which provides a method for the determination of volatile components in Gutongtiegao.The process of Thermoplastic rubber matrix is more suitable for volatile components than that of ordinary rubber matrix.
