Comparison analysis of volatile aroma components in leaves of different flavor types of Henan tobacco.

The volatile aroma components in tobacco leaves of different flavor types from Henan(Neixiang C3F and Lushi C3F) were analyzed and compared by simultaneous distillation and extraction(SDAE) and GC-MS.The results show that there were significant differences in aroma components between the two different flavor types of tobacco.Sixty nine kinds of volatile aroma components in Neixiang C3F with typical enriched flavor were identified with total contents of 436.26μg/g,in which 17 kinds of components were unique.The unique components of Neixiang C3F were 3-Methyl-2-(2-pentenyl)-cyclopentanol,2-methyl-5-(1-methylethenyl)-cyclohexanol,eudesma-4(14),11-diene and phytol,etc.Seventy two kinds of volatile aroma components in Lushi C3F with typical enriched flavor were identified with total contents of 382.55μg/g,whereas methyl heptenone,(E,E)-2,4-heptadienal,4-methyl-benzaldehyde,trans-Z-alpha-bisabolene epoxide and longifolene were unique in Lushi C3F.
