Abstract
Objective: To evaluate and compare in vitro antioxidant activity of methanol extract of the indigenous Withania somnifera with the imported root extract.
Methods: ABTS•+ radical cation de-colorization assay, DPPH• radical scavenging activity, nitric oxide radical scavenging activity, Fe2+ chelating activity assay, superoxide anion and hydrogen peroxide radical scavenging activity and ferrous reducing power were studied.
Results: The indigenous root extracts was observed comparatively better antioxidant activity than the imported root extract.
Conclusion: Indigenous root extract showed high antioxidant potential compared to the imported root extract. Present study of antioxidant activities of Withania somnifera root is the first ever report in Bangladesh.
