Abstract: The aroma components in domestic and foreign paper-making reconstituted tobaccos were analyzed. The tobacco samples were extracted with simultaneous distillation and extraction using CH₂Cl₂ as a solvent, then concentrated, and separated and identified by GC and GC/MS. About seventy aroma components were detected in each reconstituted tobacco and the relative contents of key aroma components in these reconstituted tobaccos were compared. It was found that the amount of the key aroma components in the foreign reconstituted tobacco was more abundant than in the domestic ones. The results were in good agreement with the sensory evaluation of these reconstituted tobaccos.
