Abstract: The chemical components of flue-cured tobacco between Fenghuang and main domestic and overseas were studied by comparative analysis, clustering analysis and fuzzy preferred ratio in order to know the characteristic of chemical components of flue-cured tobacco in Fenghuang. The results showed that comparing with main domestic and overseas leaves, Fenghuang leaves were higher sugar, slightly higher potassium, lower nitrogen, lower chlorine and suitable nicotine. The similarity of chemical components of flue-cured tobacco was the highest between Fenghuang County and Xingyi City Qianxinan of pure-sweetness type, followed by Xianyun County Dali and Luoping County Qujing of fresh-sweetness type. The difference of chemical components of flue-cured tobacco was more between Fenghuang County and Guiyang County Chenzhou, Xiang County Xuchan of burnt-sweetness type, and Zimbabwe and Brazil of overseas leaves. It was deduced that the aroma types of flue-cured tobacco in Fenghuang belong to intermediary-to-intense fragrance.
