FIGURE 2.

Antioxidant and free radical‐scavenging activity of CFHE1 and CFHE2 toward (a) 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH), (b) ferric reducing antioxidant power (FRAP), (c) Ferrozine, (d) β‐carotene bleaching, (e) oxygen radical absorbance capacity (ORAC) and (f) trolox equivalent antioxidant capacity (TEAC) assay. ^* p < .001 versus CFHE2; ^$ p < .001 versus reference standard: butylhydroxytoluene (BHT) for β‐carotene bleaching assay; ethylenediaminetetraacetic acid (EDTA) for ferrozine assay; trolox for DPPH, FRAP, TEAC and ORAC assays
