Preliminary Studies Regarding Antioxidant and Antimicrobial Capacity for Different Types of Romanian Honeys
Abstract
Different types of Romanian honeys were evaluated for their antioxidant and antibacterial activity. Total polyphenols, total flavonoids and two colorimetric methods for radical scavenging activity and the total antioxidant power showed different amounts of biologically active compounds in tested honey samples. Antibacterial activity was tested against Escherichia coli and Paenibacillus larvae, the first a model organism for bacteria and other a pathogenic bacterium causing American foul brood disease in Apis melliefra. Heather and honeydew honey had the highest content of total polyphenols (127.35 and 123.28 mgGAE/100 g and), while sunflower honey together with honeydew honey show the highest content of total flavonoids (64.25 and 65.98 mgQE/100 g honey). The most effective in antibacterial activity for P.larvae was found in sunflower honey whereas multifloral honey showed highest activity against E.colia) Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a Creative Commons Attribution License that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.
