This study evaluates the protective effect of corilagin against Parkinsonismin Japanese encephalitis virus (JEV) induced Parkinson’s disease. The JaGAr-01 strain of virus was used to induce JE. The virus was injected into the rats (13 days age) at the midpoint between the two ears. Adult rats, 12 week after the inoculation of virus, were used for the further study. Corilagin (20 mg/kg) and levodopa with dopa decarboxylase inhibitor (LEV, 10 mg/kg) were administered intraperitoneally for the duration of one week. Bradykinesia and the levels of dopamine in the brain were estimated at the end of protocol. There was a significant decrease inthe motor function in the corilagin, LEV and LEV + corilagin treated groupscompared to the negative control group. However treatment with corilagin, LEV and LEV + corilagin significantly increases the level of dopamine in the brain compared to the negative control group. This study concludes that corilagin ameliorates the Parkinsonismin JEV induced Parkinsonism. Moreover it shows a synergistic effect when treated with LEV. Data presented in the investigation supports that corilagin can be used clinically.
