| 中文摘要:采用硅烷化衍生化法结合气相色谱-质谱(GC-MS)法对卷烟烟丝中的主要化学成分进行检测，获得了21个卷烟样品的烟丝硅烷化GC-MS指纹图谱数据，并应用聚类分析和主成分分析法对烟丝硅烷化GC-MS指纹图谱数据进行综合评价。结果表明，该方法可用于不同品牌卷烟的比较和区分，硅烷化成分的含量分布特征能反映不同品牌卷烟的特性，可为卷烟品牌的风格表征、品质维护和真伪鉴别提供参考。 |

| Abstract:A gas chromatography-mass spectrometry(GC-MS) with silanized derivatization was developed for the determination of major tobacco constituents in 21 cigarette samples of three brands.The obtained GC-MS fingerprint data were processed by cluster analysis and principal component analysis,respectively.Results showed that the method could be used in the comparison and discrimination on cigarettes of different brands,and the proportion distribution of various silanized components reflected fairly well the characteristics of different brands of cigarettes.The developed method could provide a reference for cigarette style characterization,quality maintenance and authenticity discrimination. |
