Conc., concentration. W, water extract; WM 70/30, water–methanol (70/30, v/v) extract; WM 50/50, water–methanol (50/50, v/v) extract; WE, water–enzyme extract. Same superscript letter in one row indicates no statistically significant differences between extracts (p < 0.05); lowercase letters indicate statistical significance among different extract concentrations, and capital letters indicate the same concentration of different extracts (p < 0.05).
