不同地区不同等级复烤烟叶中重要致香物质的分析比较

Analysis and Comparison of the Important Aroma Components in Flue-cured Tobacco Leaves from Different Regions and Different Grades

本文采用同时蒸馏萃取(SDE)/气相色谱/质谱联用法(GC/MS)对相同品种、不同地区、不同等级复烤烟叶中的重要致香物质进行分析比较;并且对同时蒸馏萃取法进行重复性和回收率试验。结果表明相同品种、不同地区、不同等级复烤烟叶中重要致香物质的含量差别较大;同时蒸馏萃取法具有良好的重复性和较高的回收率。

The important flavor constituents in the flue-cured tobacco leaves from different regions and different grades were analyzed and compared with simultaneous distillation and extraction（SDE） and GC/MS; and experiments of repeatability and recovery were been done. The results is shown that the important flavor constituents in the flue-cured tobacco leaves from the different regions and different grades existed difference; the repeatability of the methods is good, and that the recovery rate is higher.
