Bioactive components, antioxidant and DNA damage inhibitory
activities of honeys from arid regions
Food Chem, 2014 Jun 15;153:28-34
Honey serves as a good source of natural antioxidants, which
are effective in reducing the risk of occurrence of several diseases. 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.
