Radical scavenging on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radicals, ferric reducing antioxidant power (FRAP), copper chelating (CCA), and iron chelating activities (ICA) of different extracts prepared from aerial vegetative organs and fruits of sea rocket (Cakile maritima). Results are expressed as IC50 values (mg/mL).

Values represent the mean ± standard error of mean (SEM) performed six times (n = 6). For the same column, different letters are significantly different (Multiple Comparisons of Means: Tukey Contrast, 95% family-wise confidence level). nr: not reached; IC50: half maximal inhibitory concentration; * positive control tested at 1 mg/mL.
