Three different unifloral Palestinian honey samples that originate from Thymus capitatus, Thymelaea hirsuta, and Tolpis virgata were analyzed by using Headspace-Solid Phase Microextraction Gas Chromatography–Mass Spectrometry (HS-SPME-GC–MS). The analysis performed exhibited chromatographic profiles that are characteristics for each type of examined honey. Therefore, the proposed analytical procedure demonstrated a rapid characterization method for the analysis of these types of honeys, by revealing the presence or absence of certain organic volatile constituents. A variety of volatiles, particularly phenols, aldehydes, ketones, acids, and alcohols were detected in these types of honeys. The compounds present in each specific honey offer a marker that can be utilized in relating a given honey to its floral origin. Thymus capitatus honey showed six marker compounds: 1,3-diphenyl-2-propanone, (3-methylbutyl)benzene, 3,4,5-trimethoxy benzaldehyde, 3,4-dimethoxy benzaldehyde, vanilline, and thymol. Thymelaea hirsuta honey is characterized by the presence of a group of alcohols and phenols particularly benzene propanol, benzylalcohol, nonanol, hexanol and 4-methoxyphenol. Tolpis virgata hooney, however, has two marker compounds 3,5-dihydroxytoluene, and tridecane.
