The investigation on locomotor activity and hypnotic effect of the decoction of Pandanus amaryllifolius root was performed in mice. The extract at doses of 1- 2 g/kg significantly decreased the spontaneous locomotor activity in a dose-dependent manner during 30 minutes after feeding. The extract at the dose of 4 g/kg significantly suppressed the locomotor activity in amphetamine-treated mice but the lower dose cannot. In addition, the extract at doses of 0.5-2 g/kg feeding prolonged the pentobarbital-induced sleeping time in both sexes of mice. This effect was not attenuated by flumazenil (a selective benzodiazepine receptor antagonist).These results suggest that the water extract of Pandanus amaryllifolius root suppressed the spontaneous and amphetamine-activated locomotor activity. The extract also potentiated the effect of pentobarbital sodium on sleep which is not implicated with benzodiazepine receptor system.
