Honey can be collected from various flowering plants and its composition of volatile compounds depends on the nectar source. The volatile profiles of 15 honey samples of different botanical origin were investigated by means of solid phase microextraction (SPME) on Carboxen™/Polydimethylsiloxane 75 µm fiber followed by gas chromatography and mass spectrometry (GC-MS). Unifloral honey samples of rape, white clover and caraway were analyzed; also two samples of multifloral honey were investigated. Analysis of honey by SPME-GC/MS enabled the separation of more than 50 different volatile compounds; however, not all compounds were identified. Identified constituents involve different classes of chemical compounds including alcohols, ketones, aldehydes, acids, terpenes, hydrocarbons, benzene and furan derivatives.
