Antioxidant Studies On Methanol And Aqueous Extracts Of Gymnosporia Montana Plant

ABSTRACT

Objective: The main objective of this study was to evaluate the free radical scavenging activity of methanol (70%) and aqueous extract of G. montana leaves which is a traditionally used herb known for its hepatoprotective activity. Methods: The in vitro antioxidant activity of G. montana extract was determined using 1, 1-diphenyl-2-picrylhydrazyl radical (DPPH), 2,2′-azinobis-(3-ethylbenzothiaziline-6-sulfonate (ABTS), Hydrogen peroxide scavenging activity, Superoxide anion radical scavenging activity and Reducing Power ability at three different concentrations (1.78µg/ml, 3.57µg/ml and 7.14µg/ml). Results: The Results revealed similar observations between the methanol and aqueous extract with respect to standard and showed potent antioxidant activity. Ascorbic acid was used as a standard, which showed IC50 value 4.71µg/ml, whereas, methanol and aqueous extract showed 5.08 µg/ml and 5.69 µg/ml. Three different concentrations were used which showed a dose-dependent non-significant increase in percent inhibition. Conclusion: Findings indicate that this plant is a good source of antioxidant and can be used for the treatment of diseases as such medicinal plant extracts are natural products and they are comparatively safe, eco-friendly, less expensive and locally available. Hence, the validation of the effects of these herbal remedies will have to be undertaken for their wider acceptance.
