烟草及烟草制品中脱氧果糖嗪含量分析

Analysis of Deoxyfructosazine in Tobacco and Cigarettes

对烟草及烟草制品中的脱氧果糖嗪测定方法进行研究,确定采用超声波提取,以蒸馏水为提取溶剂测定烟草及烟草制品中的脱氧果糖嗪含量,方法的重复性好(RSD小于5%)、回收率高(大于91%)。采用该方法检测了包括烤烟、白肋烟、香料烟在内的20种烟叶样品和25种卷烟烟丝样品,结果显示在20种烟叶样品中均未检测到脱氧果糖嗪的存在,国产卷烟基本无脱氧果糖嗪的存在或含量极低,而一些进口混合性卷烟则有较高含量的脱氧果糖嗪。

The determination method of deoxyfruetosazine in tobacco and cigarettes was studied and supersonic extraction-high performance liquid chromatography method was developed. The recovery of the DOF was more than 91 % and the relative standard deviation was not more than 5%. This method was applied to the determination of the DOF in 20 kinds of tobacco leaves and 25 cigarettes. The results showed that DOF were not exist in tobacco leaves, and the same result was found in domestic cigarette. But the DOF contents in some import blended cigarettes were much higher.
