Abstract: The study investigated the effects of the aqueous and methanol extracts of Alchornea laxiflora on two mouse models of anxiety, the elevated plus-maze and the staircase. This was with a view to providing information on the anxiolytic potential of A. laxiflora. Seven (7) groups of mice of both sexes (n=6) weighing 18 – 22 g were used for the study, which were randomized into control and the test groups. The control group (I) received 10 % Tween 80 (vehicle), 0.1 ml/10 g mouse, p.o. while the test groups (II,III,IV,V,VI) were administered graded doses (100, 200, 400, 800, 1600 mg/kg, p.o.) of the extracts. The reference group (VII) received standard drug, Diazepam (1 mg/kg, i.p.). The animals were observed for exploratory activity in the open and the close arms of the elevated plus-maze. The animals were also observed for rearing and steps-climbing of the staircase model. They were appropriately scored in the elevated plus-maze and the staircase paradigms individually 30 and 60 min post intra-peritoneal and oral administrations respectively for both the aqueous and the methanol extracts. The extracts demonstrated anxiolytic activity in the elevated plus-maze test, by the increase in the percentage entry into open arms, increase in the percentage time spent in the open arms, significant (P = 0.000) increase in the time spent in the open arms and a decrease in the index of open arm avoidance. In the staircase model, there was a significant (P = 0.000) decrease in rearing and a significant (P = 0.000) increase in the number of steps-climbing. The study concluded that the aqueous and the methanol extracts of A. laxiflora have anti-anxiety activities in mice.
