ABSTRACT

Bee Pollen is a bee product which has nutritive, anti-inflammatory, atioxidant, antitumoral, antibacterial, cardioprotective, hepatoprotective properties. This study was aimed at investigating antioxidant activity of dimethyl sulfoxide (DMSO) and water extracts of Turkish pollens. In this study, the Total Phenol Contents(TPC), Total Flavonoid Contents(TFC), Total Antioxidant Activity(TAA) and Total Antioxidant Capacity(TAC) of DMSO and water extracts of bee pollen which were collected Balıkesir, Bayburt, Erzurum and Trabzon in Turkey were measured using modified Folin-Ciocalteu, Aluminum Nitrate colorimetric method, FRAP assay and commercial kit, respectively. TPC, TFC, TAA and TAC of water and DMSO extract of pollen were found to be 5.29± 0.41 and 18.86 ± 7.98 mg Gallic acid Equivalent (GAE)/g pollen, 2.27 ± 0.14 and 5.66 ± 0.87 mg Quercetin Equivalent (QE)/g pollen, 15.96 ± 0.87 and 51.21 ± 15.23 mg Trolox Equivalent (TE)/g pollen and 0.49 ± 0.07 and 3.47 ± 0.33 mmol Trolox/100 g pollen, respectively. This results suggested that DMSO extracts of Turkish bee pollen have higher antioxidant activity than water extracts of Turkish bee pollen and both of extracts can be used as a good source of antioxidant power.
