The concentration of samples that provide 50% oxidant inhibition (IC₅₀) was calculated from the graph that plotted the oxidant inhibition percentage against different concentrations of each extract. The values are expressed as means (standard deviation) of three replicates. Mean values with different letters within a row are significantly different by Tukey test at (p < .05).
