Comparison of Acid and Phenol Compounds in Smoke Total Particulate Matter by the Different Tobacco Leaves

This study was conducted to determine the acid and phenol compounds in smoke total particulate matter(TPM) by the different tobacco variety, and grade of tobacco leaves. Sixteen kinds of tobacco leaves which were flue-curd, burley, orient, reconstituted tobacco, expanded stem, and expanded cut tobacco, were selected for this study. After collecting a TPM by using smoking machine, the concentration of TPM components was analyzed by GC. Acid components of TPM of mainstream smoke were different from the variety and grade. The order of the highest concentration of acid compounds in TPM was flue-cured > orient> burley> expanded cut tobacco> reconstituted tobacco> expanded stem. Though lactic acid and glycolic acid concentrations in flue-cured tobacco were twice higher than those in burley tobacco, the contents of 2-furoic acid and 3,4-dihydroxy butanoic acid in burley tobacco were higher than those in flue-cured tobacco. The content of phenolic compounds in the high grade and thick leaves was higher than that in other tobacco leaves. Phenol and catechol compounds in burley CD3W-2 revealed the least value in concentration among the samples tested. Pyrocatechol and hydroquinone concentrations in flue-cured tobacco were 2-3 times higher than those in burley and orient tobacco.
