Thermal degradation of beta-carotene, major carotenoid present in cured tobacco leaves, were carried out at 400, 600, and 800 deg C which were similar to temperatures existing in the combustion zones of cigarettes, and subsequent volatile degradation products were analyzed by combined gas chromatography mass spectrometry. The volatile compounds identified from degradation products included 36 aromatic hydrocarbons, 10 beta-ionone-related compounds which have trimethylcyclohexane ring, and 7 others. Of these, 37 compounds including beta-cyclogeraniol had not been previously reported in the literature as thermal degradation products of beta-carotene
