Figure 4.

Total phenols present in various concentrations of FEE (0.01–0.3 mg/ml), expressed as tannic acid equivalent (a), reducing power of FEE (0.1–3 mg/ml) compared to n-propyl gallate (0.001–0.03 mg/ml) (b), free radical scavenging ability of FEE (0.1–3 mg/ml) compared to n-propyl gallate (0.00083–0.025 mg/ml) in the DPPH radical assay (c) and percentage inhibition of lipid peroxidation by FEE (0.3–3 mg/ml) compared with that of n-propyl gallate (0.01–0.3 mg/ml) (d). Values are mean ± SEM (n = 3)
