ABSTRACT
The present study was undertaken to evaluate the anti-amnesic activity of the ethanolic extract of Acacia
nilotica bark against scopolamine-induced amnesia in Swiss albino mice. Phytochemical screening
revealed the presence of alkaloids, flavonoids, tannins, glycosides, saponins, and terpenoids. Memory
and learning were assessed using the Elevated Plus Maze, Morris Water Maze, Passive Avoidance Test,
and Novel Object Recognition Test. Treatment with the extract significantly improved cognitive
performance compared to the scopolamine-induced group (p < 0.0001). The higher dose (75 mg/kg)
produced greater improvement and showed effects comparable to the standard drug piracetam. The
findings suggest that the ethanolic extract of Acacia nilotica possesses significant anti-amnesic and memory-enhancing activity.
