ACHE and memory impairment: A considerable rise was observed in the level of AChE (33.11 ± 0.77, ### p < 0.001, n = 8) in the brain homogenate after scopolamine administration in comparison to the control group with 13.38 ± 0.59, n = 8 (Figure 7); this was effectively reversed by donepezil and F1–F5, signifying their function in the treatment of memory impairment probably via ChE inhibition.
