烟草烷烃含量研究

The alkane content study of tobacco samples

利用超声提取-GC-MS测定有代表性的不同品种、不同部位、相同烟区不同品种及相同品种不同地区的烟草中烷烃含量,并进行比较.结果表明:影响烟草烷烃含量多少的因素有品种、部位以及产地等.不同种烟叶烷烃含量香料烟最高,其次是白肋烟,烤烟含量最低;同种烟叶上部烟叶的烷烃总量最大,其次是中部叶,下部叶的烷烃含量最低.

Useing the ultrasonic extraction-GC-MS method,the paraffin content of these tobaccos were de-termined and compared which is typical for different varieties and different parts or different varieties in same region or same variety and different regions.The results showed that factors affecting the paraffin con-tent in tobacco were：varieties,location and origin.Different kinds of tobacco alkane content,in which the highest was the aromatic tobacco,followed by the burley tobacco,the lowest content was the flue-cured to-bacco.The same kind of tobacco amount of alkane content,in which the upper leaves in tobacco leaf was the largest,followed by central leaf,the alkane content of lower leaf was the lowest.
