ABSTRACT
Palynological analysis, total polyphenols, total flavonoids and antioxidant activity were studied on six samples fresh bee pollen from Transylvania. Floral origin of used bee collected pollen was identified by palynological analysis without acetolysis followed by microscopy and comparison with a library of samples. The content of total polyphenols was determined using the Folin-Ciocalteu colorimetric method with gallic acid as standard and total flavonoids content was determined with zirconium oxychloride reagent using quercetin as standard for calibration. The antioxidant properties were evaluated by 2,2-diphenyl-picrylhydrazyl radical scavenging capacity (DPPH) assay and ferric ion reducing antioxidant power assay. The content of total polyphenols and the antioxidant capacity of examined samples was different, due to the botanical origin of predominant pollen.
