Psychopharmacological studies on Tragia involucrata root extract.
The methanol fraction of the root extract of Tragia involucrata was investigated for psychopharmacological activity in rodents. It produced an alteration of behavioural pattern and a reduction in spontaneous motility. A significant potentiation of pentobarbitone-induced sleep, a decrease of body temperature, suppression of the aggressive behaviour pattern and of the conditioned avoidance response (CAR) were observed with the fraction. These suggest that the methanol fraction of the T. involucrata root extract possesses significant central nervous system depressant action.
