| Abstract: |
| The differences of volatile organic compounds in various cigarette samples were investigat? ed in order to analyze the aromatic characteristics of different tobacco products. Five commercial ciga? rette brands were selected for the research of volatile organic compounds in cigarette samples using headspace－gas chromatography－ion mobility spectroscopy（HS－GC－IMS），while the typical aro? matic matters were analyzed by relative odor activity value（ROAV）. The HS－GC－IMS analysis re? sults showed that the volatile organic compounds of five selected cigarette samples were almost the same. Nevertheless，the contents of each sample were quite different. ROAV analysis showed that the main volatile organic compounds were aldehydes，ketones，alcohols and esters while the key sub? stances contributing most to the cigarette aroma were 2-furanmethanethiol，1-octene-3-one，furan al? cohol，3-methylbutyraldehyde，3-methylbutyl acetate，etc. The different aroma threshold values af? fect their contribution to the aromatic styles of cigarettes. Based on HS－GC－IMS and ROAV analy? sis，the typical aromatic matters could be analyzed，which will provide a technical support for the style analysis and quality evaluation of different cigarettes. |
