  1. EC50 (mg/mL) values are half-maximal effective concentrations. DPPH and ESR-alkyl radical scavenging activities were quantified using catechin as the positive control, and ABTS radical scavenging activity was quantified using α-tocopherol as the positive control. Means and standard deviations are from three independent experiments (N = 3)
