Fig. 2.From: Purification, structural analysis, and stability of antioxidant peptides from purple wheat branThe profiles of PWBP hydrolysates using size exclusion chromatogram on a Sephadex G-25 column (a) and superoxide anion radical scavenging activity and TEAC of various fractions at peptide concentration of 5 mg/mL. Means (n = 3) followed by the same letter were not significantly different according to Duncan’s multiple range test at P < 0.05 levelBack to article page
