Evaluation on Chemical components of Tobacco Leaves from Different Aromatic Flue-cured Tobacco Production Areas

To improve the quality of tobacco leaves,72 tobacco leave samples with three grades were collected from 8 aromatic flue-cured tobacco production areas(Anhui Wannan,Guangdong Nanxiong,Henan Xuchang,Henan Luohe,Henan Nanyang,Hunan Liuyang,Hunan Chenzhou and Shandong Weifang) and were analyzed for evaluating their main chemical components.The results showed that the changes of chemical components observed mainly in the aspects of total sugar,reducing sugar,potassium,chlorine,total sugar/nicotine and K/ Cl.The content of total sugar,reducing sugar,potassium and the ratio of sugar/nicotine,K/Cl were higher in the tobacco leave samples from southern production areas(Anhui Wannan,Guangdong Nanxiong,Hunan Liuyang and Hunan Chenzhou) than from the production areas of Yellow River and Huai He River(Henan Xuchang,Henan Luohe,Henan Nanyang,Shandong Weifang).The ratio of K/Cl in samples from four former areas was favorable and the total sugar/nicotine in samples from four latter was appropriate.
