Studies on the Essential Oils of Tobacco Leaves: Part I. Acid FractionPart II Carhonyl FractionPart III Phenol Fraction

We are studying exhaustively the steam distillable components “Essential Oils” of the formented Virginia tobacco leaves which consist of acids, bases, phenols, carbonyls and neutral compounds. At first we have tried the estimation of volatile organic acids contained in essential oils, and isolated and identified formic, acetic, isobutyric, trans-crotonic, n-caproic, benzoic and phenylacetic acids by procedures using chromatography and infrared spectra. On the other hand, we also isolated a kind of fatty acid by the same procedure and estimated that it would be a pentoic acid. We could find no report which has proved the presence of trans-crotonic, phenylacetic and a pentoic acids in tobacco leaves.

The presumption that some carbohydrates contained in the Virginia tobacco leaf converge to some furfural compounds in the stage of steam distillation was proved to be correct. The content of furfur...
