Antidepressant-like effect of asiaticoside in mice

In the present study, the potential antidepressant properties of asiaticoside were investigated in male mice in three tests -- splash test in the unpredictable chronic mild stress (CMS) model, tail suspension test (TST), forced swimming test (FST) -- with clomipramine being a positive control. In the splash test, asiaticoside (10 mg/kg, PO) and clomipramine (50 mg/kg, PO) significantly augmented the frequency of grooming behavior in stressed mice. In the tail suspension test, asiaticoside (10, 20 mg/kg, PO) and clomipramine (50 mg/kg, PO) significantly decreased immobility time. In the forced swimming test, asiaticoside (10, 20 mg/kg, PO) and clomipramine (50 mg/kg, PO) significantly decreased immobility time. These results suggest that asiaticoside may have antidepressant-like action.
