A headspace (HS)/solid phase microextraction (SPME)/gas chromatography-mass spectrometry (GC-MS) method was developed to determine the profiles of volatile compounds from three Cuban unifloral honeys: Turbina corymbosa (L.) Raf., Ipomoea triloba L. and Gouania polygama (Jacq.) Urb. The optimization of the extraction conditions was carried out by response surface methodology. The analytical conditions of the optimized HS-SPME method were: 65 mm PDMS/DVB fiber, 6 g honey, 3 mL water and 20% w/w sodium chloride, 20 min for pre-extraction, 30 min for extraction at 60C and 4 min for GC desorption. The GC-MS analysis allowed the identification of 181 volatile compounds in these honeys. Possible markers for the floral classification of honeys were for the T. corymbosa type: 4-methyl methoxysalicylate, trans-pinocarveol, chavicol, methyl anisate, trans-abergamotene and a-bisabolol. In I. triloba honey, 2,5,5-trimethyl-3-tetrahydrofuranone and 1,2-diphenylethanol were found, while 5 Corresponding
