[Objective] This study was aimed to find a new method for the classifica-tion of common aroma components in tobacco leaves. [Method] Sixty-four common aroma components in tobacco leaves were classified by cluster analysis based on their relative molecular weight. The contents and distribution of aroma components in another 71 C3F and 64 B2F tobacco leaf samples were analyzed by using the new method. [Result] The 64 common aroma components were divided into three cate-gories trough the cluster analysis based on their molecular weight. CategoryⅠ con-sisted of 12 aroma components which had high molecular weight (281.308 ±21.536 on average) and high boiling point (371.311±29.904 ℃ on average). Category Ⅱ in-cluded 27 components which had low molecular weight (103.722 ± 13.115 on aver-age) and low boiling point (176.132±42.342 ℃ on average). Category Ⅲ included 25 components which had middle molecular weight (175.393 ± 24.906 on average) and middle boiling point (250.562±45.431 ℃ on average). The content of high-molecular-weight aroma components in middle leaves (547.344±224.391 μg/g) was much high-er than that in upper leaves (477.549±182.066 μg/g). The content of low-molecular-weight aroma component in middle leaves (17.468±3.459 μg/g) was also significantly higher than that in upper leaves (15.936±3.456 μg/g). The content of middle-molec-ular-weight aroma component in middle leaves (44.931 ±8.953 μg/g) was extremely significantly higher than that in upper leaves (37.997±6.042 μg/g). [Conclusion] This study proposed a new way to classify the aroma components in flue-cured tobacco leaves using the relative molecular weight as the index, which wil provide theoretical reference for developing special tobacco leaves.
