Data presented as mean (n = 3) ± SD values for the same parameter evaluated followed by different superscript lowercase letters are significantly different at p < 0.001, according to Tukey’s test. Y Level of significance: *** significant at p < 0.001. The standard inhibitor was galanthamine for AChE, BChE, and Kojic acid for TYR.
