The chemical constitution of antioxidants contained in honey is derived from its origin. Forty honey samples, which came from various locations of the Czech Republic and varied in their origins, were evaluated spectrophotometrically for their total polyphenol content, total flavonoids and 3',4'-dihydroxyflavones and flavonols, and major antioxidants were identified by HPLC-DAD and GC-MS. In the Czech honey, ferulic acid and chrysin other minority phenolics and flavonoids were identified and quantified as honey phenolic antioxidants contained. The results obtained support and extend complete knowledge on the contents of bioactive phenolics in the Czech honey, which could serve as a good source of natural antioxidants effective in reducing the risk of the occurrence of heart disease, cancer, cataracts, different inflammatory processes and immuno-system decline.
