Antioxidant Capacity of Bee Pollen Associated with Type, Not Concentration of Polyphenols and Flavonoids

A Comparison of Methods Used to Define the Antioxidant Capacity of Bee Pollen and Beebread from Romania
43rd Croatian & 3rd International Symposium on Agriculture, February 18 – 21, 2008

Abstract: The total content of phenolic compounds and flavonoids were measured in bee pollen and beebread extracts, as well as their antioxidant activity. The content of total polyphenols was quantified according to the Folin-Ciocalteau spectrophotometric method…

A great variability regarding the correspondence between the antioxidant activity and the content of total polyphenols and flavonoids of bee pollens with different botanical origin was found. Antioxidant activities were different for each species and were not clearly associated to their antioxidant content…

The results of this preliminary study, conducted on bee pollen from different plant sources and beebread from Romania, demonstrated that the polyphenolic and flavonoid composition, rather that the concentration, could be the determinant factor. Our results suggested that the antioxidant capacity of samples might be associated with their specific compounds...
