We evaluated anti-Parkinson’s activity of methanolic extract of Juniperus communis (MEJC) leaves in chlorpromazine (CPZ) induced experimental animal model. In this study effects of Juniperus communis (100 and 200 mg/kg, i.p.) were studied using various behavior parameters like catalepsy (bar test), muscle rigidity (rotarod test), and locomotor activity (actophotometer) and its effect on neurochemical parameters (TBARS, GSH, nitrite, and total protein) in rats. The experiment was designed, by giving chlorpromazine (3 mg/kg, i.p.) for 21 days to induce Parkinson’s disease-like symptoms. Chlorpromazine significantly induced motor dysfunctions (catalepsy, muscle rigidity, and hypolocomotion) in a period of 21 days. The MEJC significantly () reduced catalepsy and muscle rigidity and significantly () increased locomotor activity in rats. The maximum reduction was observed on the 21st day at a dose of 200 mg/kg (i.p.). The MEJC extract also showed an increase in the level of reduced gutathione (GSH) () and total protein () and decreased the elevated levels of TBARS () and nitrite () preferably at a higher dose (200 mg/kg) as compared to chlorpromazine group. Thus the present study showed the neuroprotective effect of MEJC against CPZ induced Parkinson’s disease-like symptoms or anti-Parkinson’s activity.
