Abstract: In order to analyze the differences in the composition of volatile substances of honeys from different floral sources in the Western Sichuan Plateau, the volatile compounds of rape, Angelica sinensis, Sophora davidii and multifloral honeys were determined using an electronic nose (E-nose) and headspace solid-phase micro extraction coupled with gas chromatography-mass spectrometry (HS-SPME-GC-MS) and the E-nose sensor response data were analyzed by principal component analysis (PCA) and linear discriminant analysis (LDA). The results showed that the E-nose was sensitive to detect the differences in volatile components of four honey samples. A total of 40, 51, 39 and 46 volatile substances were detected by HS-SPME-GC-MS in these samples, respectively, mainly including alcohols, esters, ketones, aldehydes and hydrocarbons. In addition, 7 volatile components were found common to all the tested samples, exclusively containing 22, 27, 26 and 19 compounds, respectively. In conclusion, E-nose combined with GC-MS analysis can successfully distinguish among the volatile components of honey from different sources.
