| 摘 要： | 我国主要烟叶类型烟草特有亚硝胺(TSNA)水平排序为:白肋烟 > 沙姆逊香料烟 > 烤烟 > 巴斯马香料烟,其平均含量分别为10.25、0.89、0.25和0.03 μg/g。在白肋烟和香料烟中,NNN和NAT为主要的TSNA,约占总TSNA的96%,且在总TSNA含量较高的烟样中,NNN占有较大比例。在烤烟中,NNN、NAT和NNK含量水平相差较小,且以NAT含量相对较高。我国烤烟型、混合型、雪茄型卷烟和雪茄的总TSNA含量平均分别为0.211、3.302、3.39和12.66 μg/g。与国外样品相比,我国烤烟烟叶、烤烟型卷烟和混合型卷烟TSNA含量均显著低于国外水平。相关分析表明,烟叶和卷烟中的TSNA含量与降烟碱水平呈显著正相关,其中NNN与降烟碱相关性最大,相关系数达0.8633。

| Abstract: | The order of TSNA levels in major Chinese tobacco types is determined to be burley > Oriental (Samsun) > Flue-cured > Oriental (Basma) with the average total TSNA content of 10.25,0.89,0.25 and 0.03 μg/g, respectively. NNN and NAT are the principal nitrosamines in burley and Samsun tobacco. NNN content is always the greatest in samples with higher levels of TSNA. In flue-cured tobacco no big difference among the levels of NNN,NNK and NAT was found. TSNA contents in Virginia, blended, cigarillo and cigar were 0.21,3.03,3.39 and 12.66 μg/g, respectively. Correlation of individual alkaloids to individual TSNA with all samples indicated that NNN with nornicotine has highest correlation coefficient of 0. 8633. |
