摘要
通过加速溶剂萃取法分离烟草中的香味物质,对烟草中10多种醛酮类香味物质用GC/MS进行定性分析,并用内标法进行定量分析,采用正交实验方案探讨了加速溶剂萃取分离烟草香味物质的优化条件,比较了该方法与同时蒸馏萃取对分析结果的影响。结果显示:加速溶剂萃取简便、快速,易于操作,重复性令人满意,回收率范围是80.3%～106.4%,比同时蒸馏萃取法略好。
The accelerated solvent extraction （ASE） was used to extract aromatic compounds in tobacco, and more than 10 aldehydes and ketones were identified and determined by gas chromatography/mass spectrometry. The optimum conditions for ASE （heating time, solvent volume and extraction time） were investigated with orthogonal array design. The results of ASE and simultaneous distillation extraction （SDE） were compared. The results indicate that the ASE is simple, rapid and easy-to -operate, its repeatability is satisfactory, and the recoveries are in the range of 80.3-106.4%. The ASE is a little better than SDE.
