To clarify the quality of burley tobacco in China, the physical properties and main chemical components of burley tobacco leaves in China during 2004-2014 were analyzed. The results showed that, the physical properties and chemical components of the annual burley tobacco leaves in the annual 2004-2014 years were different, but there was no regularity between the annual fluctuations. Leaves thickness, equilibrium moisture content, tensile strength and elongation of burley tobacco from four main producing areas of China in Hubei Enshi, Sichuan Dazhou, Chongqing Wanzhou, Yunnan Binchuan were not significant, the leaf density, filling value, percentage of stem and leaf quality were significant differences. The total sugar, petroleum ether extract content and pH values of burley tobacco form four areas were not significantly differences, the total alkaloid, total nitrogen, potassium and chlorine content in different parts of tobacco from different areas were different.
