Abstract:
Antioxidant properties of fifteen multifloral and honeydew types of honey
from Serbia were assessed by determination of ferric-reducing antioxidant
power (FRAP assay) and 2,2- diphenyl-1-picrylhydrazyl free radical scavenging
ability (DPPH assay), with respect to their total polyphenol content and
colour intensity. The results of this study showed that total polyphenol
content, antioxidant activity and colour intensity varied widely among
different samples, even within the same type of honey. All investigated
parameters were strongly dependent on geographic origin of samples, further
emphasizing the importance of their detailed chemical characterisation. In
general, polyphenolic content in investigated samples of honey, expressed as
catechin equivalents, ranged from 480.2 to 1861.1 mg/kg. The ferric-reducing
antioxidant power of honey tended to be lower in brighter and higher in
darker samples, varying between 489.6 and 3089.8 ?mol Fe(II) per 100 g of
honey. The correlation between the colour and antioxidant activity never
reached statistical significance in the case of honeydew type of honey, which
was opposed to a trend observed in the case of multifloral honey.
