Abstract：The composition and content of conventional chemical constituents and neutral aroma compo -nents were analyzed and compared in flue -cured tobacco from six tobacco production counties in Pingdings -han.The results showed that the average contents of total sugar and reducing sugar were 23.45％ and 19.37％, 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, potassi-um 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 neutral fragrant components was the highest in Yexian tobacco area reaching 1102.8μg/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 ace-tone, 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 sol-anone 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 be -tween different produce areas.
