EC50: equivalent concentrations of test samples scavenging 50% of DPPH radical. Data represent the mean ± SD of three independent experiments carried out in triplicate. In the same column, values earmarked by different superscript letters (a–d) are significantly different according to one-way ANOVA and Waller-Duncan test; .
