摘 要:应用气相色谱法/原子发射检测器(GC/AED)分离检测主流烟气粒相物中的含氮碱性成分。3种类型烟叶(典型烤烟、白肋烟和香料烟)、不同香型烤烟烟叶和成品卷烟经过吸烟机抽吸后,收集主流烟气粒相物。粒相物经过连续萃取和反萃取分离,得到含氮的碱性成分,进行GC/AED检测。结果表明,GC/AED能够检测出主流烟气中吡嗪类、吡啶类和烟草微量生物碱类成分。比较了不同样品含氮成分的异同,结果表明,白肋烟烟叶主流烟气粒相物中含氮成分较多,含量最高,烤烟和香料烟烟叶主流烟气粒相物中含氮成分相对较少,含量较低;不同香型烤烟烟叶主流烟气粒相物中主要含氮成分基本类似;不同品牌卷烟主流烟气粒相物中主要含氮成分基本类似,烤烟型卷烟假木贼碱相对百分含量较高(3.84%~4.62%),而混合型卷烟降烟碱相对百分含量较高(5.22%)。Compounds containing N element in particulate matter of mainstream smoke of different tobacco samples were isolated and determined by GC/AED. The particulate matters of mainstream smoke from 3 types of tobacco leaves ( typical flue-cured tobacco leaf, hurley tobacco leaf and oriental tobacco leaf), different flavor flue-cured tobacco leaves and cigarettes with different brands were collected through smoking machine. The particulate matter was successively extracted with different solvents. Then alkaline extraetants containing N element were collected and determined by GC/ AED. The results showed that the derivatives of pyrazine, pyridine and tobacco trace alkaloids could be detected by GC/AED. The compounds containing N element in different samples were compared.The kinds and amount of compounds containing N element in the particulate matter of mainstream smoke of burley tobacco leaf were more than those in flue-cured tobacco and oriental tobacco leaves. The kinds and amount of compounds containing N element in the particulate matter of mainstream smoke of different flavor tobacco leaves were similar. And those in cigarettes with different brands were also similar. However, there were more anabasine (3.84% ~ 4. 62% ) in flue-cured cigarette and more nornicotine (5.22%) in blended tvoe cigarette.
