Abstract :The purpose of this study was to investigate antioxidant and antimicrobial activities of selected honeys, chestnut n = 15 , Bayburt n = 8 and Anzer n = 7 from Turkey. Antioxidant activity was evaluated by the following three methods: scavenging of 2,2-diphenyl-1-picrylhydrazyl DPPH free radicals, total phenolics and ferric reducing/antioxidant power FRAP . Antimicrobial activity was studied by agar diffusion method by using eight bacteria and two fungi. The antioxidant activities were found to be related to the sample concentrations. The phenolic contents of the honeys were found to be significantly related with antioxidant activities with a correlation coefficient of R2 = 0.77. All samples showed moderate antimicrobial activity, especially against Helicobacter pylori, Staphylococcus aureus and Klepsiella pneumonia. No activity was observed against the two fungi, Candida albicans and Candida tropicalis.Keywords : Anzer, Antioxidant, Antimicrobial, Honey
