为探究不同类型烟草叶片挥发物成分成分差异，[方法]利用顶空动态吸附法收集烟草挥发物，采用气相色谱质谱联用技术对其组分及含量进行分析。[结果]结果表明，不同类型烟草叶片挥发物组分和含量存在差异，豫烟11共检测到51种挥发物，8306共检测到50种挥发物，云烟87共检测到48种挥发物，粤烟98共检测到44种挥发物，K326共检测到43种挥发物，晒黄烟共检测到34种挥发物，香料烟共检测到25种挥发物。其中，烤烟鉴定出17种特有化合物。晒黄烟鉴定出6种特有化合物。香料烟鉴定出4种特有化合物。[结论]这些化合物的发现与不同类型烟草间的香味风格特征的形成密切相关。
Abstract
To explore the differences of leaf volatile constituents and the sources of aromatic characteristics in different types of tobacco leaves, Tenax-TA was used to adsorb volatiles in different types of tobacco leaves by the dynamic headspace procedure. The components and contents were analyzed by gas chromatography-mass spectrometry. The results showed that there were differences in the volatile components and contents of different types of tobacco leaves. A total of 51 volatiles were detected in‘Yuyan 11’, 50 volatiles were detected in‘8306’, 48 volatiles were detected in‘Yunyan 87’, 44 volatiles were detected in‘Yueyan 98’, and 43 volatiles were detected in‘K326’. A total of 34 volatiles were detected in the sun-cured tobacco, and 25 volatiles were detected in the oriental tobacco. Among them, 17 unique compounds were identified in the flue-cured tobacco, six unique compounds were identified in the sun-cured tobacco, and 4 unique compounds were identified in the oriental tobacco. The conclusion reveals that the discovery of these compounds is closely related to the aromatic characteristics of different types of tobacco.
