Tinospora cordifolia is reported to have CNS active principle and is used for the treatment of various neurological disorders. Hence, the effect of aqueous ethanolic extract of Tinospora cordifolia was investigated for its putative antipsychotic activity using amphetamine challenged mice model. Haloperidol (1 mg/kg i.p.) was administered acutely to mice as standard drug. Control animals received vehicle (10% DMSO). The in vivo receptor binding studies were carried out to correlate the antipsychotic activity of the extract with its capacity to bind to the DAD2 receptor. The results in SLA showed that the hydro alcoholic extract of the stems of Tinospora cordifolia at a dose level of 250 mg/kg and 500 mg/kg showed no significant antipsychotic activity in amphetamine induced hyperactivity in mice when compared to standard. Extract alone treated group at a dos level of 250 mg/kg and 500 mg/kg showed a decreased in locomotor activity when compared to the control. The plant extract increased the DAD2 receptor binding in a dose dependent manner in treated mice compared to the control group.
