辛夷挥发油化学组分的GC/MS分析及在卷烟加香中的应用

Analysis of Components in Volatile Oil from Lily Magnolia with GC/MS and its Application in Tobacco Flavoring

摘要: 首次采用超临界CO₂流体萃取辛夷挥发油,平均出油率为4.15%。利用GC、GC/MS法对辛夷挥发油进行了化学组分的定性和定量分析,共鉴定出55种组分。并用辛夷挥发油进行了卷烟加香试验。结果表明,辛夷挥发油能明显改善和修饰卷烟香气,有降低烟气的粗糙度、改善吸味、减轻刺激性、去除杂气的作用。参考添加量为1.50×10^-5~1.75×10^-5。

Abstract: The dry flowers of Lily Magnolia were extracted with supercritical CO₂ fluid. The average yield of the resulting volatile oil was about 4.15%. The chemical components in the oil were qualitatively and quantitatively analy zed by GC/MS, and fifty-five compounds were identified. The oil was applied in cigarettes as a tobacco flavoring. The results showed that the oil could significantly reduce the harshness, eliminate the offensive odor, and improve the taste of cigarette smoke. The applied amount of the oil was about 1.50×10^-5 to 1.75×10^-5.
