Hydrogen peroxide scavenging of ethanol Bucida buceras extract (400–1600 μg/ml) at 1 h in (a) 1600 μM H2O2 pulse y = 0.0415x - 3.2327, R2 = 0.99336 (IC50 = 1356.29 μg/ml) and (b) 50 mU/ml of GOx y = 0.0277x - 3.8591, R2 = 0.98872 (IC50 = 2050.09 μg/ml). (c) DPPH-scavenging activity of Bucida buceras (5 a 50 μg/ml), y = 1.6486x +6.8934, R2 = 0.976 IC50 = 26.14 μg/ml. (d) The ferric ion reducing antioxidant power (FRAP) in concentrations of 100 to 800 μg/ml. Values above the bars indicate % of inhibition. Each value is expressed as mean ± SD (n = 3)
