Introduction: Depression is a prevalent psychiatric disorder affecting 3.8% of the global population. The clinically available antidepressants can cause serious adverse effects. Aegle marmelos fruit has shown a wide range of pharmacological effects. The present study was carried out to elucidate the possible antidepressant activity of Aegle marmelos (Bael) fruit in Swiss albino mice. Objective: To evaluate the possible antidepressant activity of Aegle marmelos fruit extract in Swiss albino mice. Methods: A total of 30 (n=30) male Swiss albino mice weighing 25-35 g, divided into five groups of six animals each were used for the study. Aegle marmelos fruit powder was subjected to solvent extraction in a soxhlet apparatus. The antidepressant activity of the hydroalcoholic extract of Aegle marmelos fruit was evaluated by using two models –Forced Swimming Test (FST) and Tail Suspension Test (TST). Results: One-way ANOVA was used for multiple comparisons followed by a post hoc (Bonferroni test) for comparison between groups. Aegle marmelos fruit at the dose of 100mg/kg and 200 mg/kg significantly reduced the immobility time in both the tests (TST and FST) compared to the control. The reduction in duration of immobility at the dose of 200 mg/kg was comparable to the standard drug Imipramine. Conclusion: The Hydroalcoholic extract of Aegle marmelos has significant antidepressant activity in both the animal models of depression (FST and TST).
