Radical scavenging assay of bass extraction with DPPH (0.25 mM 2,2-diphenyl-1-picrylhydrazyl) corresponded for 30 min. (A) Ascorbic acid standard of DPPH radical scavenging assay. (B) The radical scavenging ability of bass protein. (C) The radical scavenging ability of bass oil. Graphs were presented as the mean of triplicate ± SEM (p < 0.05). Superscripts a, b, c, d and e indicate significant differences of radical scavenging ability depending on concentration of bass protein and oil by one-way ANOVA of variance.
