摘　　要：采用二氯甲烷同时蒸馏萃取前处理,结合毛细管GC及GC-MS技术,对许昌襄城烤烟不同叶位(8～12叶位)中性香味物质成分及含量进行了对比分析.结果表明:不同叶位适熟烟叶从第8到12叶位大部分香味物质,如二氢猕猴桃内酯、巨豆三烯酮Ⅰ、金合欢基丙酮、苯甲醇、苯乙醇、2-乙酰基吡咯、糠醛、茄酮含量呈现先升后降的趋势,到第10叶位达到最高;第10叶位各类香气物质总量最高,新植二烯、二氢猕猴桃内酯、金合欢基丙酮、2-乙酰基吡咯、茄酮等物质含量明显偏高;第12叶位中β-大马酮、巨豆三烯酮Ⅲ、香叶基丙酮、3-氧化-α-紫罗兰醇、苯甲醛含量明显偏高;第11叶位中除美拉德反应产物类香气物质总量、类西柏烷类香气物质总量外,香气物质总量、新植二烯的含量、类胡萝卜素降解产物总量、芳香族氨基酸类香气物质总量仅次于第10叶位;第8叶位中3-羟基-β-二氢大马酮、巨豆三烯酮Ⅱ含量明显偏高.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, Megastigmatrienone I, 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 1 lth leaf position were next to the 10th leaf position. 3- Hydroxy-13-damascone, Megastigmatrienone Ⅱ in the 8th leaf position were obviously higher than the other four leaf positions.
