GC-MS Fingerprints and Other Physico-chemical Characteristics of Rare Unifloral Prunus cerasus L. Honey

GC-MS fingerprints of unifloral sour cherry (Prunus cerasus L.) honey were investigated for the first time by GC-FID and GC-MS {; ; after headspace solid phase microextraction (HS-SPME) and ultrasonic solvent extraction (USE)}; ; . Additionally, other physico-chemical characteristics of the samples were determined (total phenolic content, antioxidant activity and CIE L*a*b*C*h chromatic coordinates). The principal volatile components of the honey headspace were lilac aldehydes (46.0 ; 50.6%) along with benzaldehyde (18.0 ; 19.4%). The dominant component of the dichloromethane USE extract was vomifoliol (39.6 ; 44.9%). The abundant identified compounds may only serve as non-specific markers of the honey’s botanical origin since they also occur in other honey types. The honey contained low-moderate amount of polyphenols (209.0 - 309.5 mg GAE/kg) and exhibited moderate antioxidant activity (0.4 - 0.6 mmol TEAC/kg ; 1.6 - 1.9 mmol Fe 2+ /kg).
