Abstract: In order to study chemical constituents, a cluster and comparative analysis was conducted on 73 flue-cured tobacco middle leave samples from 42 counties in Hunan tobacco-growing areas. The results showed that the total sugar, reducing sugar and sugar-nicotine ratio of Hunan flue-cured tobacco were high, chlorine had a large coefficient of variation and a low content. The difference of chemical constituents was highly significant in different areas, the chemical constituents of flue-cured tobacco samples in Jiahe and Zhijiang were in line with high-quality tobacco production requirements. Hunan tobacco-growing areas fell into 3 categories according to clustering results. Multiple comparisons showed that all chemical indicators, except total nitrogen and chlorine, were significantly different. Differences among categories can supply different materials for cigarette companies.
