The objective of the present study was to evaluate the anxiolytic and antidepressant activities of methanol extract of Aegle marmelos (AM) leaves as well as its interaction with conventional anxiolytic and antidepressant drugs using elevated plus maze and tail suspension test in mice. Albino mice were treated with AM (75, 150 and 300 mg/kg, po), imipramine (20 mg/kg, po), fluoxetine (20 mg/kg, po), and combination of sub-effective dose of AM with imipramine or fluoxetine. Effects were observed on (a) time spent on (b) number of entries into (c) number of stretch attend postures (d) number of head dips in arms of elevated plus maze and on duration of immobility in tail suspension test. Effects of pretreatment with prazosin (0.062 mg/kg, po), haloperidol (0.1 mg/kg, po) and baclofen (10 mg/kg, po) were also studied on AM induced decrease in duration of immobility. Effects of AM (75, 150 and 300 mg/kg po) were observed on locomotor activity using photoactometer. Results showed that AM significantly (P<0.05) and dose dependently increased proportionate time spent on and number of entries into open arms while decreased number of stretch attend postures and head dips in closed arms. Dose dependent and significant (P<0.05) anti-immobility effect was found in mice treated with AM. Combination of AM (75 mg/kg, po) with imipramine (5 mg/ kg, po) or fluoxetine (5 mg/kg, po) also produced significant (P<0.05) anxiolytic and antidepressant activity. Antidepressant activity of AM (150 mg/kg, po) was significantly (P<0.05) decreased by prazosin, haloperidol and baclofen. Methanol extract showed insignificant (P>0.05) effect on locomotor activity of mice. It is concluded that AM possess potential anxiolytic and antidepressant activities and it enhances the anxiolytic and antidepressant activities of imipramine and fluoxetine.
