Abstract
Brassica oleracea var. capitata rubra extract with different solvents [methanol, ethanol. Water, acetone and chloroform] were analyzed for antioxidant activities. The antioxidant activities were evaluated based on the ability of the plant extracts to DPPH radical scavenging assay, FRAP assay, reductive activity, superoxide radical scavenging activity, Lipid peroxidation assay and Nitric oxide scavenging assay. Ascorbic acid is used as standard. It was found that methanol extract (70%) has potent antioxidant when compared to the other extracts. Ethanol and chloroform extract showed the second highest antioxidant activity (59%) followed by acetone extract (25%). Least activity was shown by water extract (22%) in DPPH assay. The results proved that the overall antioxidant activity were highest in methanol extract as compared to others The information of this study helpful to choose the solvent extracts for the further pharmacologic studies.
Key words: Brassica oleracea var. capitata rubra, antioxidant activity, radical scavenging.
