Abstract:In order to develop a new natural cigarette flavor, Trollius chinensis Bunge was extracted with supercritical CO2 method, then the volatile oil was pyrolyzed under simulated condition of process of smoking. The pyrolytic products were measured and analyzed by Py/GC-MS method and its applications to cigarette flavoring were studied as well. The results showed that: 1) 43, 41 and 37 constituents were identified in the pyrolytic products at 300℃, 600℃, 900℃, respectively. They were mainly aldehydes, alkenes, acids and ketones which have their characteristic flavor. 2)The volatile oil of Trollius chinensis Bunge extracted with supercritical CO2 was characterized by enhancing the aroma quality and volume of smoke, reducing irritancy and improving the aftertaste.
