The aim of this study was to investigate the effects of sarsasapogenin from Anemarrhena asphodeloides BUNGE (Liliaceae) on the forced swimming test, and the central noradrenergic, dopaminergic and serotonergic activities in mice. Our results showed that sarsasapogenin treatment at 12.5, 25 and 50mg/kg (p.o.) for 14d significantly reduced the duration of immobility in the forced swimming test. These doses that affected the immobile response did not affect locomotor activity. In addition, the neurochemical assays showed that sarsasapogenin produced a marked increase of noradrenaline and serotonin levels at 50mg/kg in both the hypothalamus and the hippocampus. Moreover, sarsasapogenin showed a monoamine oxidase inhibitory activity in the mouse brain. These findings suggest that the antidepressant activity of sarsasapogenin may involve the central monoaminergic neurotransmitter systems.
