Study on the Pyrolytic Behavior of the Extract of Trollius chinensis Bunge and Application of Unblended Cigarette Flavoring

The extract of Trollius chinensis Bunge was pyrolyzed under simulated condition of process of smoking. Then the pyrolytic products were measured by Py-GC-MS under different temperatures of 300, 600 and 900 ℃, respectively, and the applications of the extracts in unblended cigarette flavoring were studied as well. The results showed that 28, 29 and 31 constituents were identified in the pyrolytic products at 300 ℃, 600 ℃, 900 ℃, respectively. Pyrolysis products were mainly acids, esters, alcohols, phenols, aldehydes and ketones, which were beneficial to the smell of tobacco flavor. The extract from Trollius chinensis Bunge was characterized by enhancing the aroma quality and volume of smoke, reducing irritancy and improving the aftertaste.
