Assessment of antioxidant activity of Digera muricata extracts by different methods

Abstract
Free radical accumulation is the cause of many
oxidative stress related disorders like diabetes, arthritis, neurodegenerative
diseases, cardiovascular diseases and cancer. Due to negative health effects of
synthetic antioxidants substantial attention is shifted towards finding novel
antioxidants of plant origin. In the present study antioxidant activity of Digera
muricata root extracts was evaluated using various in vitro
assays. DPPH free radical, superoxide radical, hydroxyl radical scavenging ability,
metal chelating activity, calculation of reducing power as well as total
phenolic content of five different extracts was determined at different
concentrations. Methanolic extract exhibited highest antioxidant activity for
various assays and total phenolic content in methanolic extract was found to be
38.22 mg/g gallic acid equivalent. Significant positive correlation was found
between total phenolic content and in vitro assays indicating that phenolic acids may be the major contributors
for antioxidant activity. Data from present results suggests that D.
muricata has significant antioxidant activity and could serve as potential
source of natural antioxidants.
