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.
