Effect of D. integrifolia on scopolamine-induced memory impairment on retention parameters in the morris water maze. Latency to the non-existing platform (A). Time spent in the target quadrant (B). Each column represents mean ± SEM of six animals. The data analysis was performed using one way ANOVA followed by Tukey multiple comparisons test ^∗∗P < 0.01, ^∗∗∗P < 0.001; vs. scopolamine-alone treated group (DW + Sco). ^ap < 0.05, ^bp < 0.01, ^cp < 0.001 vs. distilled water group. DW, distilled water; DI, D. integrifolia; Sal, saline; Sco, scopolamine; Tac, tacrine.
