In order to investigate the feasibility of the extract from Cyclocarya paliurus as an additive in cigarettes, the volatile aromatic components were analyzed by gas chromatography-ion mobility spectrometry (GC-IMS), and C.paliurus extract was pyrolyzed to simulate cigarette smoking by TGA-GC/MS. The cracking products of C.paliurus were analyzed in a nitrogen environment, and the possible cracking mechanism of the products was reasonably speculated. The results showed that aldehydes, alcohols, and ketones were the primary volatile aroma components of the C.paliurus extract, comprising 62.28% of the total aroma components. The cracking products of C.paliurus extract varied greatly under different temperature conditions. A total of 79 compounds were identified at 200,360, and 440 ℃, among which 24 aromatic components were clearly identified as having significant effects on cigarette style, including aldehydes, ketones, alcohols, phenols, furans, benzene series, and other natural aromatic substances. Among them, phenols containing a high concentration are mainly formed by compounds containing the structure of guaiacol unit and eugenol unit by side chain cleavage, demethylation, demethoxylation, dehydration, etc. Furan and its derivatives are mainly formed by glycosides or glycoside compounds by breaking glucoside bonds and dehydration.
