Dose dependent decrease of locomotor activity of mice. Tween 80 (10 mg/kg) as vehicle, petroleum ether extract of Amorphophallus paeoniifolius (100, 300, 1000 mg/kg) and diazepam (0.5, 1.5 mg/kg) as standard drug were administered intra-peritonially. After 60 min of drug treatment, decrease of locomotor activity was determined by actophotometer. The data is expressed as mean±SD of n=6 observations; *P<0.05 as compared to control; ANOVA followed by Dunnett's test. Control refers to 5% v/v Tween 80 solution.
