45 kinds of main chemical components of aroma in flue-cured tobacco were identified by GC/MS. Components in cured leaves of different pH value around roots were quantitatively determined by GC. The main chemical components of aroma matter gained were neopphytidiene; nicotine; solanone; benzeneacetaldehyde; 10-isopropyl-3, 7, 13-trimethyl-2, 6, 11, 13-tetradecaen-1-ol; cembratrienes, etc. Contents of aroma chemical components in flue-cured tobacco under different pH value were obviously different. The pH value between 6.5 and 7.5 was beneficial to aroma quality of flue-cured tobacco, and pH value above 8.0 had an unfavourable effect on the formation of some important components of aroma matter. In addition, it was possible that pH value around roots influenced aroma character of flue-cured tobacco
