Abstract
Smoke condensates of lamina and midrib cigarettes of flue-cured tobacco leaves were subjected to glass capillary column gas chromatography without fractionation. A flame thermionic detector (FTD), which is specific for N-containing organic compounds, was used. By this method, pyridines, pyrroles and lactams were determined simultaneously. Nicotine was a major component, in both smokes. In regard to the other components, degradation products of nicotine predominated in lamina smoke, while pyrazines and oxygenated N-compounds predominated in midrib smoke. In this study, several N-containing compounds were found for the first time in tobacco smoke.
