The cut tobacco in cigarette samples was prepared with optimized simultaneous distillation and extraction by using phenylethyl acetate as an internal standard (IS). The aroma components in the samples were analyzed by GC/MS with selective ion mode. 24 basic aroma components, including pyridine, thiazole, pyrrole, and 34 neutral aroma components, including furfural, furfuryl alcohol, β-ionone, in tobacco were accurately quantitated. The results showed that: the recoveries of neutral aroma components ranged from 73.05% to 97.35% with RSDs below 10%, among them the recoveries of 20 components were above 80%. The recoveries of basic aroma components ranged from 71.49% to 98.93%, of which the RSDs of 22 components were less than 10%, RSDs of 2-methyl pyrazine and tetramethyl pyrazine were 14.96% and 11.81%, respectively.
