Statistical significance was expressed as p-value. All experiments were repeated 3 times. For DPPH assay, p-valute were expressed as *p < 0.05 vs. CON; **p < 0.001 vs. CON; #p < 0.05 vs. Vit C; ##p < 0.001 vs. Vit C; +p < 0.05 vs. H.W; ++p < 0.001 vs. H.W; $p < 0.05 vs. 20% EtOH; $$p < 0.001 vs. 20% EtOH; @p < 0.05 vs. 40% EtOH; @@p < 0.001 vs. 40% EtOH; &p < 0.05 vs. 60% EtOH; &&p < 0.001 vs. 60% EtOH; %%p < 0.001 vs. 80% EtOH, For reducing Power and total Phenolic Content *p < 0.05 vs. CON; **p < 0.001 vs. CON; #p < 0.05 vs. H.W; ##p < 0.001 vs. H.W; +p < 0.05 vs. 20% EtOH; ++p < 0.001 vs. 20% EtOH; $p < 0.05 vs. 40% EtOH; $$p < 0.001 vs. 40% EtOH; @p < 0.05 vs. 60% EtOH; $$p < 0.001 vs. 60% EtOH; &p < 0.05 vs. 80% EtOH; &&p < 0.001 vs. 80% EtOH.
