Abstract: 〗Five conventional constituents in 202 flue-cured tobacco samples from two tobacco areas (Longshan and Sangzhi) of Xiangxi in 2006 were analyzed and evaluated.By the comparison with that from Yunnan,it was found that the content of total sugar in Xiangxi tobacco was higher than the sugar range of good quality tobacco,but lower than that in Yunnan tobacco.For most tobacco samples in Xiangxi,the content of nicotine was in a suitable but slightly high level and higher than that from Yunnan.The content of Cl-1 and total nitrogen was within a suitable range,as well as the ratio of TS/alkali and K/Cl.The ratio of TS/alkali in tobacco from Xiangxi was generally lower than that from Yunnan and TN/alkali ratio lower than good quality tobacco.In order to further improve the quality of tobacco in Xiangxi areas,it is necessary to improve bionomic and cultivated conditions and to utilize flue-cured and modulation technique so as to reduce the content of total sugar and nicotine and to increase the content of K in Xiangxi tobacco.

Key words: flue-cured tobacco, chemical constituents, evaluation, Xiangxi
