Significant linear correlations were found between extract total phenols content and antioxidant activity measured by the reducing power assay (EC50 (mg/mL) = −0.024×total phenols (mg GAE/g extract) + 3.096; R2 = 0.903; P < 0.001) and by the DPPH assay (EC50 (mg/mL) = −0.008×total phenols (mg GAE/g extract) + 0.966;R2 = 0.837; P < 0.001).
