Using a previously described gas chromatographic method, the relative amounts of neutral substances were studied in the smoke of bright cigarettes made from tobaccos of different aromaticity. The analytical results were compared with panel test findings on the relative flavor of the cigarettes. Some tendency toward a relationship was found between certain higher boiling neutral components and smoke flavor; among these components was a peak containing neophytadiene and other substances which may be of special importance in this regard. No correlation was apparent when total neutral components were evaluated. Relationships between the ratios of neutral substances to total acids and relative smoke flavor were also discussed.
