Figure 4: DPPH free radical scavenging activity of different concentrations of HRE (1050 g/mL) and -tocopherol (50 g/mL) was spectrophotometrically measured at 517 nm using the DPPH radical assay (HRE: Hexanoic extract of Hippophae rhamnoides L.; DPPH: 1,1-diphenyl-2-picryl-hydrazyl; n=3). * p< 0.001, with respect to control, by ANOVA (Tukeys post test).
