  1. Data are expressed as mean ± S.E.M, n = 3. DPPH radical scavenging activity, hydroxyl radical scavenging activity (HRSA), and superoxide radical scavenging activity (SRSA) are expressed as the IC50 value (mg/ml). TEAC, FRAP, and FICP are expressed as mg trolox/mg dried extract, mmol FeSO4/mg dried extract, and mg EDTA/mg dried extract, respectively.
