Data are expressed as mean ± SD (n = 3).
Mean with different alphabet within the same column indicate significant differences (p < 0.05; Tukey).
Asterisk symbol indicates the positive controls.
AChE, acetylcholinesterase; BuChE, butyrylcholinesterase; GMHW, hot water extract; GMM, methanol extract; GME, ethanol extract; GMMG, fraction G.
