Abstract: In order to recognize the producing areas of flue-cured tobacco leaves, the characteristic volatile aroma components in the leaf samples collected from 11 counties in Liangshan and Yibin, including Ningnan, Dechang, Puge, Huidong, Huili, Yanyuan, Mianning, Yuexi, Xingwen, Gongxian, and Junlian, were analyzed by GC/MS, and then the cluster analysis was performed. The results showed that:1) 46 of the identified volatile components were common to all the samples and were treated as the variables in cluster analysis. The samples were clustered into three groups by producing areas i.e. southern Liangshan, northern Liangshan and Yibin. 2) 7 volatile components (nicotine,farnesyl acetone,palmitic acid,ledol,geraniol,α-cembratriene-diol and β-cembratriene-diol) of higher relative contents and more stable in the samples from southern Liangshan and Yibin were selected as the variables for further cluster analysis, and the results were basically the same as those with the 46 volatile components. It was believed that the characteristic volatile components with higher relative contents and more stable in leaves could be used for the discrimination of producing areas of tobacco.
