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.
