Free radical scavenging activity of quercetin 50 μM, BHT 227 μM, DHA 80 μM, EPA 80 μM and OA 80 μM as measured by colorimetric 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Quercetin and BHT were included as positive controls. Absorbance values for the diluent (BSA) were subtracted from all data sets. Data are expressed as mean ± SEM and are representative of four independent experiments.
