摘要:

为探究不同种类烟草浸膏挥发性成分的差异,本研究采用顶空固相微萃取-气相色谱-质谱联用法(HS-SPME-GC-MS)对白肋烟、香料烟和豫烟这3种浸膏中的挥发性成分进行分析,并结合正交偏最小二乘判别分析(orthogonal partial least squares discriminant analysis,OPLS-DA)筛选出关键差异挥发性成分。结果表明,3种烟草浸膏中共检测出111种挥发性成分,其中杂环类、烃类和酮类化合物含量占比达到了90%以上;3种烟草浸膏中的共有挥发性成分有33种,不同种类烟草浸膏的挥发性成分在种类和含量上存在较大差异。OPLS-DA结果表明,苯甲醇、苯乙醛、α-大马酮、茄尼酮、4,7,9-巨豆三烯-3-酮B、4,7,9-巨豆三烯-3-酮D和新植二烯是不同种类烟草浸膏中关键的差异挥发性成分,可在一定程度上对不同种类的烟草浸膏进行区分。本研究可为不同种类烟草浸膏香气特征优化提供一定的理论参考。

Abstract:

In order to explore the differences in volatile components of different types of tobacco extracts,headspace solid-phase microextraction gas chromatography-mass spectrometry(HS-SPME-GC-MS)was used to analyze the volatile components in three types of extracts:burley tobacco,spice tobacco,and Yuyan tobacco. The key differential volatile components were screened by orthogonal partial least squares discriminant analysis (OPLS-DA). The results showed that a total of 111 volatile components were detected in the three tobacco extracts,with heterocyclic,hydrocarbon,and ketone compounds accounting for over 90% of the total content. There were 33 volatile components in three types of tobacco extracts,and there were significant differences in the types and contents of volatile components in different types of tobacco extracts. The OPLS-DA results indicated that benzyl alcohol,phenylacetaldehyde,α-damascenone,solanone,4,7,9-megastigmatrien-3-one B,4,7,9-megastigmatrien-3-one D,and neophytadiene were key differential volatile components in different types of tobacco extracts,which can be used to distinguish different types of tobacco extracts to some extent. This study can provide a theoretical reference for optimizing the aroma characteristics of different types of tobacco extracts.

Key words: tobacco extract, volatile component, orthogonal partial least squares discriminant analysis(OPLS-DA)
