This study was undertaken to address the limited knowledge regarding the
polyphenolic content, antioxidant and DNA damage inhibitory activities of honeys produced in arid
regions and compare them with well-recognized honeys from non-arid regions. Different types of honey
were assessed for their contents of total phenolics, total flavonoids, and certain types of phenolic compounds.
The antioxidant capacity of honey was evaluated by ferric-reducing/antioxidant power assay
(FRAP), free radical-scavenging activity (DPPH), nitric oxide (NO) radical-scavenging assay, total antioxidant
activity, and DNA damage. Results clearly showed significant differences among honeys with all the
evaluated parameters. Results also showed that one or more types of honey from arid regions contained
higher levels of phenolic compounds, free radical-scavenging activities, or DNA damage inhibitory activities
compared with the evaluated honeys from non-arid regions.
