Abstract：
:A total of 58 polyfloral honey samples from different regions in Serbia were studied to determine their phenolic profile, total phenolic content and antioxidant capacity. UHPLC-LTQ OrbiTrap MS made possible the identification of 36 compounds: 24 flavonoids, two abscisic acids, and 10 phenolic acids and their derivatives. Quantification was done using 14 available standards. Data on phenolics and abscisic acids allowed the discrimination and classification of honeys in accordance to their geographical origin, using pattern recognition techniques, principal component analysis and partial least squares discriminant analysis. Samples originated from Vojvodina and Zlatibor region were clearly distinguished from those from the rest of Serbia because of the presence of dicaffeoylquinic acid, ellagic acid, caffeic acid phenethyl ester, and chlorogenic acid, among others. A good correlation (r = 0.865) was observed between total phenolic content and radical-scavenging activity. Total phenolic content ranged from 0.03 to 1.39 mg GAE/g and radical scavenging activity ranged from 1.31% to 25.61%.
