摘要: The present study investigated the antidepressant effect of ethanol extract Paeonia lactiflora (EPL) in mice using forced swim test, tail suspension open-field test and reserpine test. Our results showed that intragastric administration EPL at doses 250 500 mg/kg for seven days significantly reduced duration immobility both dose was as effective positive control (chlorimipramine, 20 mg/kg) these tests. However, treatments did not affect number crossing rearing Treating with antagonized reserpine-induced ptosis hypothermia. 125 mg/kg, only hypothermia but induced by reserpine. clearly demonstrated animal models depression. action may be mediated via central monoaminergic neurotransmitter system.
