Protective effects of P. spinosa fruits extracts on human plasma under oxidative stress conditions: (a) influence on the nitration of tyrosine residues in plasma proteins and formation of 3-NT; (b) impact on the lipid peroxidation and TBARS generation; (c) effects on the NEAC value of plasma (assessed by FRAP). Data expressed as mean values ± SE (n = 7–9). Statistical significance: ### p < 0.001 for control plasma versus ONOO−-treated plasma in the absence of the investigated analytes; *** p < 0.001 for ONOO−-treated plasma in the presence of the extracts (1–50 μg/mL) or model compounds/positive controls (5 μg/mL) versus ONOO−-treated plasma without the analytes. QU, quercetin; CYG, cyanidin 3-O-glucoside; CHA, chlorogenic acid; AA, ascorbic acid; TX, Trolox®.
