Phenolic profile and antioxidant activity of bee pollen extracts from different regions of Algeria
Abstract
Due to its complex biochemical properties, the bee pollen is considered one of the functional foods. Bee pollen collected from pollen grains from different botanical sources offers almost a full diet such as carbohydrates, proteins, amino acids, vitamins, minerals. In this study, methanol extracts of 13 honeybee pollen samples were evaluated for flavonoids, phenolic compounds, and antioxidant capacity. Caffeic acid, chlorogenic acid, vanillic acid, p-coumaric acid, gallic acid, quercetin, rutin, vanillin, and naringin were identified as main phenolic compounds in pollen extracts by High-Performance Liquid Chromatography (HPLC) analysis. The obtained results are: total phenolic content - 379.8 to 915.6 mg GAE/100 g, total flavonoid content - 207.1 to 550 mg QE/100 g, and antioxidant activity - 808.2 to 3311 mg GAE/100 g in bee pollen extracts.
