Headspace solid-phase microextraction-gas chromatography–mass spectrometry characterization of propolis volatile compounds
Abstract(#br)In this study, a novel and efficient method based on headspace solid-phase microextraction (HS-SPME), followed by gas chromatography–mass spectrometry (GC–MS), was developed for the analysis of propolis volatile compounds. The HS-SPME procedure, whose experimental parameters were properly optimized, was carried out using a 100\u003cce:hsp sp=\"0.25\"/\u003eμm polydimethylsiloxane (PDMS) fiber.
