Aim: Evaluation of Antioxidant and Anti-Parkinson activity of Portulaca oleracea seed methanolic extract.
Place: C. U. Shah College of Pharmacy and Research, Wadhwan, Surendranagar, Gujarat, India.
Methodology: Collect plant materials were extracted with methanol. Extract was subjected to qualitative and quantitative investigation and antioxidant properties of extract was determine by Nitric oxide free radical scavenging activity and Reducing power by FeCl3 method.
Anti-Parkinson activity evaluated by two behavioral models namely, haloperidol induced catalepsy, and orofacial dyskinesia both models various behavioral activity/ parameter (catalepsy, vacuous chewing movement and tongue protrusion) were evaluated.
Results: Preliminary qualitative phytochemical screening was to reveal presence of polyphenols, flavanoids, glycoside, alkaloids, carbohydrates and reducing sugar etc. Based preliminary qualitative phytochemical screening; quantitative estimation of methanolic extract showed significant amount of polyphenols. In-vitro antioxidants was performed by two method reducing power by FeCl3 and nitric oxide free radical scavenging, the methanolic extract shows significant antioxidant properties, based on polyphenols and antioxidant properties extracts was used for the Anti-Parkinson activity Haloperidol induced catalepsy in mice Treatment with Portulaca oleracea seed showed a significant (P<0.01) reduction in the duration of cataleptic behavior dose dependently when compared to haloperidol treated group. Haloperidol induced orofacial dyskinesia in rat recovery of orofacial dyskinesia as evidenced by decrease in the frequency of vacuous chewing movement and tongue significant (P<0.05) decrease in the frequency of vacuous chewing & tongue protrusion while Portulaca oleracea seed (200 mg/kg) was found to be insignificant in this respect.
Conclusion: After Portulaca oleracea seed (MLPO) treatment, the significant alterations produced in Parkinson’s affected rodents in respect to lipid peroxidation and antioxidant concentration significantly contributing its antioxidant potential. This antiperoxide action observed in Portulaca oleracea seed (MLPO) treated animals might be due to the suppression of the production of reactive oxygen species. This compound may be found to scavenge free radicals, including hydroxyl anions and reduce the level of lipid peroxidation in MLPO animals. Inhibition of oxidative stress may be one of the possible mechanisms for the anti-Parkinson effects of Portulaca oleracea seed (MLPO).
