采用同时蒸馏萃取法提取烟叶中的挥发性成分, 利用气相色谱-质谱联用仪(GC-MS)分离测定, 通过谱库检索和匹配度定性结合色谱保留指数方法鉴定烟叶中挥发性成分, 并引入离子阱二级质谱对谱库检索匹配度差距小、含量低,背景干扰大的物质准确定性. 采用谱图检索结合二级质谱定性共鉴定144 个化合物, 其中104 个化合物在烟草挥发性成分的文献中已有报道, 报道中有9 个化合物是通过二级质谱定性, 其余40 个化合物还未见报道. 结果表明, 离子阱二级质谱定性的引入提高了对未知化合物定性的准确性和可靠性, 适合于烟叶这类复杂植物体系的化学组分研究.

The volatile components in tobacco leaves were extracted by simultaneous distillation and extraction (SDE), and analyzed by gas chromatography-mass spectrometry (GC-MS). The volatile components in tobacco leaves were identified by library searching and spectral matching combined with retention index. Ion trap tandem mass spectrometry was introduced to identify some components which had tiny difference of library matching, low concentration, and complex matrix. 144 components were identified by library searching, spectral matching and ion trap tandem mass spectrometry in this paper. And 104 volatile components have been reported, 9 of them were identified by ion trap tandem mass spectrometry, the other 40 components have not been reported in the literature. So ion trap tandem mass spectrometry is the precise and reliable method to identify some unknown components, and is suitable for separation and identification of complex system.
