Abstract
Total phenolic and flavonoids phytochemical concentration was measured in bee pollen samples, Appis Mellifera , as well as their botanical origin, antioxidant activity and antimicrobial activity. Pollen loads were washed with 70% ethanol and identified using a 400x magnification. The content of total polyphenols and flavonoids was measured spectrophotometrically with gallic acid and quercetin as standard. The antioxidant activity was evaluated by the linking capacity of (i)the free radical DPPH (2,2-Diphenyl-1-picrylhydrazyl), (ii)ORAC and (iii)system β-carotene/linoleic acid. The experiments were performed in triplicate and the results expressed as mean ± stand...
