A gas chromatography-mass spectrometric(GC-MS) method was established for the simultaneous determination of 6 kinds of characteristic compounds,including furaneol,isoamyl isovalerate,maltol,menthol,ethyl maltol and anethole in cigarette.The sample was extracted with dichloromethane solution,concentrated with the rotary evaporation instrument,and analyzed by GC-MS.The conditions for sample preparation(e.g.sample volume,extraction solvent and extraction time) were optimized.Under the optimal conditions,the correlation coefficients of 6 analytes were higher than 0.998.The average spiked recoveries were in the range of 86%-92% with relative standard deviations(RSDs,n=6)of 4.7%-7.1%.The detection limits(S/N=3)and quantitation limits(S/N=10) were in the range of 0.014 7-0.074 6 μg/g and 0.048 9-0.248 8 μg/g,respectively.The method showed good extraction efficiency,high sensitivity and good reproducibility,and was suitable for the simultaneous detection of 6 compounds in cigarette flavoring.The results also indicated that the method could be used for the evaluation of the uniformity of cigarette flavoring on the processing line through determination of the characteristic compound contents in samples. |
