Abstract

Thirty chestnut and twenty-six of floral honeys were collected from different regions of Turkey. The amounts of phenolic compounds in honeys were determined by high performance liquid chromatography-diode array detection. The antioxidant capacities were determined by ABTS and CHROMAC methods. The total phenolic content of honeys were determined by spectrophotometric method using the Folin-Ciocalteu reagent. Caffeic, protocatechuic, and p-hydroxybenzoic acids are the major phenolic compounds with the contents of 44.52, 17.48, and 21.50 mg/kg, respectively in chestnut honeys. Chestnut honeys exhibited the higher antioxidant and better antimicrobial activities, and than the floral honeys. Floral honeys contain similar amounts of propolis flavonoids such as pinocembrin, chrysin, and galangin. The results show that these flavonoids can be used as chemical markers in honey samples.
