Tobacco flavor samples 1146 and 1133 were analyzed using a method of flash evaporation-gas chromatography/mass spectrometiy (FE-GC-MS). The resulls showed that 350℃ as the optimized flash evaporation temperature and 0.4 mg as injection amount for tobacco favor samples were selected. Eighteen constituents in sample 1146 and thirteen constituents in sample 1133 were successfully identified and quantified by GC-MS. Pyridine, glycerine and theobromine were the main components in sample 1146, and 5-hydroxymethyl furfura, pyridine, 5-methylfural were the main components in sample 1133. Compared with ultrasound-assisted liquid-tiquid extraction (ULLE), ihis method was shown to be rapid and simple in the determination of tobacco flavor constituents with good repeatability.%采用闪蒸-气相色谱-质谱法对膏状的1146、黏稠状的1133两种烟用香精香料样品进行测定,并考察样品量和闪蒸温度对实验的影响.结果表明,0.4mg样品在350℃下闪蒸可以得到最佳色谱图,且重现性良好.对两种样品1146和1133进行定性分析,定性出样品1146中的18个组分以及样品1133中的13个组分.前者中主要含有吡啶、甘油、可可碱等组分,后者中主要含有5-羟甲基糠醛、吡啶、5-甲基糠醛等组分.将该法与超声波辅助液液萃取法比较,结果显示,闪蒸-气相色谱-质谱法更适用于这两种黏稠及膏状烟用香精香料的分析检测.
