The experiment was done in triplicate and the data expressed as mean $\pm$ SEM, with $n = 3$ . Data within rows with a common superscript alphabet are not significantly different from others chemical at TPC (p < 0.05), superscript number are not significantly different from others chemical at TFC (p < 0.05) and superscript roman numerals are not significantly different from others chemical at DPPH (p < 0.05) (two-way ANOVA, followed by Tukey’s test).
