摘要: The neutral flavor components in stem and lamina of flue-cured tobacco were respectively extracted by the simultaneous distillation and extraction (SDE)apparatus and determined by GC and GC/MS.Some neutral flavor components in stem and lamina of flue-cured tobacco were compared quantitatively.The level of most neutral flavor components, notably benzyl alcohol, β-damascenone, megastigmatrienones, neophytadiene and phytone, was high in lamina than in stem.The content of aldehydes, such as furfural and phenylacetic aldehyde, was high in stem than in lamina.The total amount of aldehydes determined in stem was 2.31 times as higher as that in lamina. In addition, the neutral flavor components in stem of flue-cured tobacco grown in two provinces of China, Yunnan and Henan, were compared.
