Free radical scavenging potential of the aqueous extract of roots of Baliospermum montanum Muell-Arg, a medicinal plant, was evaluated by using diphenyl-picryl-hydrazyl (DPPH) assay and nitric oxide (NO) scavenging assay. The in vitro antioxidant activity of the plant extract was determined by DPPH and NO scavenging activity method.
