Fig. 3 shows the FRAP analysis of PFSP or PFA extracted with different solvents. As occurred with the DPPH or FIC assays, a concentrationdependent reducing power was observed for all the samples assayed. BHT, at all concentrations showed the highest (pb0.05) ferric reducing capacity in terms of mM trolox equivalents (mM TE). As occurred with the DPPH assay, the PFSPD and PFSPM samples showed a higher (pb0.05) ferric reducing capacity than the PFAD and PFAM samples. In PFSP, no statistical differences were found (p>0.05) at a high concentration (100 mg/mL) between the PFSPD and PFSPM samples. As regards PFA, the PFAD samples showed a higher (pb0.05) ferric reducing capacity at all concentrations than PFAM samples.
