The objective of this research was to test the antidepressant effect of hydroalcoholic extract of the leaves of Hypericum laricifolium (Chinchango) in albino mice. In modified forced swimming test (FST) all animals were immerse in a cylindrical pool for 15 minutes (habituation session), then they were treated every 12 hours as follows: Group 1 (n = 13) Vehicle 5 ml / kg, Group 2 (n = 13) diazepam 10mg/kg, Group 3 (n = 13) Hypericum l (n = 13) 1% 100 mg / kg and Group 4 (n = 13) Hypericum l 10% 1000 mg / kg and four hours after the session was equal to the last experience, for 5 minutes. We recorded the time of immobility, swimming and climbing for each animal. In the tail suspension test (TST) the animals were treated every 12 hours as Group 1 (n = 11) Vehicle 5 ml / kg, Group 2 (n = 11) Fluoxetine 10mg/kg Group 3 (n = 11) Hypericum l (n = 11) 1% 100mg/kg Hypericum l Group 4 10% 1000 mg / kg. Twenty-four hours later the mice were individually suspended by the distal third of the tail (test suspension of the tail) the immobility time was recorded for 6 minutes. In the FST (Forced Swimming Test) Hypericum l groups 1% and 10% showed a reduction in the immobility time in relation to the control group 170, 167 vs 231 seconds respectively; swimiming time for the Hypericum l group and 10% compared to the control group was 112 vs 48 seconds respectively, no significant changes in the time of climbing. TST in animals with Hypericum l to 10% and fluoxetine showed a significant reduction of immobility time in relation to the control group 65, 42 vs 108 seconds. In conclusion, the hydroalcoholic extract of the leaves of Hypericum laricifolium have antidepressant effect in mice with a greater effect on the concentration of 10%.
