Abstract: GC/MS was used to analyze the contents of neutral aroma components for upper and middle stalk position air-cured leaves from 6 different curing barns, and experimental cigarettes were made to conduct sensory evaluation.Results showed that the total contents of neutral volatile aroma components for middle position leaves followed the order of bamboo-mud barn＞black plastic with grass barn＞all-black plastic barn＞plastic covering structure＞wooden plate barn＞tile-roofed barn, and for upper position leaves the order was bamboo-mud barn＞black plastic with grass barn＞plastic covering structure＞wooden plate barn＞all-black plastic barn＞tile-roofed barn.When neophytadiene was deducted from the total, the lowest level was for plastic curing structure.High contents of carotenoid catabolites ( megastigmatrieonel,β-damascone et al) and cembratriendiol catabolite ( solanone) in both stalk position leaves, and phenylalanine and sugar catabolites in upper stalk position leaves were found for bamboo-mud barn and black plastic with grass barn.Lower levels of aroma components in middle stalk position leaves and carotenoid catabolites in upper stalk position leaves were found for wooden plate barn and tile-roofed barn.The lowest content of solanone was found in cured leaves from plastic covering structure and all-black plastic barn.The sensory evaluation score followed the order of bamboo-mud barn＞black plastic with grass barn＞all-black plastic barn＞plastic covering structure＞wooden plate barn＞tile-roofed barn．
