Neutral aroma components in different leaf positions of flue-cured tobacco in Xuchang were comparatively analyzed by a capillary GC equipped with FID and NPD, And GC/MS. The results indicated that: Most aroma components of mature tobacco leaves from eight to twelve increased first and decreased afterwards with the increasing of the leaf position from the 8th up to the 12th leaf and the maximum components was found at the 10th leaf position,such as Dihydro actinidiolide, MegastigmatrienoneⅠ, Farnesalacetone, Benzyl alcohol, Phenylethyl alcohol, 2-Acetylpyrrole, Furfural, Solanone; Various kinds of aroma components in the 10th leaf position were the highest, and Neophytadiene, Farnesalacetone, 2-Acetylpyrrole, Solanone, Dihydro–actinidiolide were obviously higher than those of others; β-Dmascenone, MegastigmatrienoneⅢ, Geranylacetone, 3-Oxo-α-ionol, Benzaldehyde components in the 12th leaf position are obviously higher than the other four leaf positions; Besides the Marillard reaction products and cembrane aroma components, aroma components,neophytadiene, carotenoid degradation products and aromatic amino reaction products components in the 11th leaf position were next to the 10th leaf position. 3- Hydroxy-β-damascone, MegastigmatrienoneⅡin the 8th leaf position were obviously higher than the other four leaf positions.
