Neuroprotective potential of antioxidant potent fractions from<i>Convolvulus pluricaulis</i>Chois. in 3-nitropropionic acid challenged rats

Abstract

Systemic administration of 3-NP showed marked motor deficits and oxidative damage in rats. Only FrB showed significant antioxidant activity and on further purification gave pure compound (scopoletin). Our study showed that FrB (20 mg/kg) pre-treatment significantly attenuated the loss in body weight, improved the locomotor activity, grip strength, and gait abnormalities. It also has attenuated the increased malondialdehyde and nitrite levels, and restored superoxide dismutase and reduced GSH enzyme activity in the striatum and cortex in 3-NP-treated groups. These results suggest that C. pluricaulis Chois. exhibits a neuroprotective effect by accelerating brain antioxidant defense mechanisms in 3-NP-treated rats.
