Studies on the Essential Oils of Tobacco Leaves

Part VIII. Carbonyl Fraction (3)

Abstract

The constituents and contents of the carbonyl compounds, contained in the essential oil of Virginia tobacco leaves, were compared before and after redrying and aging. In the course of the redrying and aging stage, furfural, isobutyraldehyde and the estimated C₆-al-dehyde decreased, while, on the contrary, 5-hydroxymethylfurfural and 5-methylfurfural increased. Acetone is the only constituent that has been found after redrying and aging.
