(A) DPPH-, (B) hydroxyl-, (C) superoxide-, (D) ABTS-radical scavenging activities and (E) lipid peroxidation inhibition of the WG-9 peptide. GSH was used as a positive control for scavenging properties, while BHA was considered for the lipid peroxidation assay. The assay was carried out in triplicate. ABTS = 2,20-azinobis (3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt; BHA = butylated hydroxyanisole; DPPH = 1,1-diphenyl-2-picrylhydrazyl; GSH = glutathione.
