Objective: To investigate the flavor components of Epimedium extract and analyze pyrolysis products of the extracts from Epimedium. Methods: Ultra fast gas phase electronic nose was adopted to analyze volatile components in ethanol extracts of Epimedium and the alcohol extracting process of Epimedium was optimized by orthogonal experiment. Epimedium extract was pyrolysed to simulate cigarette smoking by TG-GC-MS. The lysates of Epimedium extract were analysed in a nitrogen environment, and the possible lysate mechanism of the products was reasonably speculated. Results: 22 volatile components were detected in the ethanol extracts of Epimedium at different concentrations. Concentration of Epimedium extracted with 60% ethanol was superior than others. Analyzing pyrolysis products of Epimedium extract, 78 compounds were identified at 150, 300 and 450 ℃, including aldehydes, ketones, alcohols, phenols, furans and benzene series. Conclusion: Ethanol extraction of Epimedium contains many aromatic volatile components. A large number of ketones, alcohols, phenols, furans and other volatile aroma compounds are produced after pyrolysis of Epimedium extract.
