Abstract: Simple correlation analysis and canonical correlation analysis were used to analyze the relationship between important aroma components and aroma quality, aroma quantity, aftertaste, mixed gas, irritancy and total score of smoking quality in red suncured tobacco leaves from in Sichuan, Jilin, Jiangxi, Hunan, Guizhou, Zhejiang, Shandong, and Heilongjiang. The results showed that 22 aroma components were closely related to smoking quality, among which β-damascenone, 3-hydroxy-2-damascenone, 3-methyl crotonaldehyde, amyl alcohol, isoamyl alcohol, furfural, 2-acetyl furan, 2-pentyl furan, 2-methyltetrahydrofuran-3-one, 5-methyl furfural, solanone, safranal, indole, gamma butyrolactone , pyrrole, norsolandion and 1,3,7,7-four methyl-2-oxygen double ring 4.4.0 decyl-9-one had a positive effect while isophorone, benzaldehyde, benzene acetaldehyde, phytol-2, 3-acetyl pyridine,2-methyl-2-hepten-6-one and 2-ethylpyridine had a negative effect on smoking quality.
