ANTI-PARKINSONIAN ACTIVITY OF VARIOUS SOLVENT EXTRACTS OF CLEOME GYNANDRA LEAVES AGAINST MPTP AND ISOLATION OF PHYTOCONSTITUENTS

Abstract

Antiparkinsonian activity of Cleome gynandra (CG) was evaluated and chemical constituents were isolated. The results of the present study showed that spontaneous motor activity, retention time and number of head drippings were decreased, whereas immobility time in Tail suspension (TST) and Forced swimming test (FST) were increased in MPTP treated animals, while they were significantly (P<0.001) increased and (P<0.01) decreased with various extracts of CG. Dopamine, serotonin (P<0.001), epinephrine (P<0.01) and glutathione levels were significantly decreased and lipid peroxidation was increased in MPTP treated groups, while their levels were significantly (P<0.001) increased and decreased with various extracts of CG in a dose dependant manner as compared to MPTP, L-dopamine and control groups. Ethanolic leaf extract of CG leads to isolation of triterpenoid, flavone and anthocyanidin - O- methylated flavonoids, which were characterized by using spectroscopic investigation methods like FTIR, NMR and MS.
