摘　　要：以平顶山6个产烟县(市)调制后烟叶为材料,研究其烤烟常规化学成分和中性致香成分组成和含量的差异。结果表明:(1)6个产烟县(市)烟叶总糖和还原糖含量均值分别为23.45%和19.37%,还原糖、总糖、糖氮比的变异系数较大,分别为25.89%、24.18%、25.51%;烟碱、总氮、钾、氯含量平均值分别为2.35%、2.59%、2.03%和0.65%;蛋白质含量为7.89%;淀粉含量偏高,平均值为6.60%。除氯和淀粉含量外,其余常规化学指标及比值处于适宜范围之内,各指标有一定差异,但差距不大。(2)中性致香成分总量以叶县烟区最高,达到1 102.8μg/g,舞钢最低,为905.27μg/g,且各产区烤烟中性致香成分总量间差异显著。类胡萝卜素降解产物中的β-大马酮、巨豆三烯酮2、巨豆三烯酮4、香叶基丙酮、法尼基丙酮、β-二氢大马酮,棕色化反应产物中的糠醛,芳香族氨基酸裂解产物中的苯甲醇,西柏烷类降解产物中的茄酮和叶绿素降解产物中的新植二烯的含量,较同类降解产物所占的比重较高,且各产区间有一定差异。The composition and content of conventional chemical constituents and neutral aroma components were analyzed and compared in flue-cured tobacco from six tobacco production counties in Pingdingshan. The results showed that the average contents of total sugar and reducing sugar were 23. 45% and19. 37%,respectively. The variation coefficients of reducing sugar,total sugar and ratio of sugar to nitrogen were 25. 89%,24. 18% and 25. 51%,respectively. The average contents of nicotine,total nitrogen,potassium and chlorine were 2. 35%,2. 59%,2. 03% and 0. 65%,respectively. The protein content was 7. 89%.The starch content was higher and its mean was 6. 60%. The above indicators were within the appropriate range expect chlorine and starch,and there were little differences between them. The total amount of neutralfragrant components was the highest in Yexian tobacco area reaching 1 102. 8μg/g,while that was the lowest in Wugang as 905. 27 μg/g. The differences in total aroma components of flue-cured tobacco were significant between different counties. The contents of β-ketamine,monascalinone 2,monascalinone 4,geranyl acetone,feniyl acetone,β-dihydrocarbamate of carotenoid degradation products,the content of solane of brown reaction products,the content of benzyl alcohol of aromatic amino acid cleavage products,the content of solanone of the cembranoids degradation products and the content of neophytadiene of chloraphyll degradation products were higher in the proportion of similar degradation products,and there were some differences between different produce areas.
