Different biochemical reactions in our body generate free radicals and these are capable of damaging crucial biomolecules. Mushrooms have the capacity to destroy such free radicals formed in our body as they possess antioxidant properties. The purpose of this study was to determine the antioxidant activities of mushroom, Pleurotus cornucopiae collected from Eastern Himalayan region. Antioxidant activity was determined using reducing power assay, DPPH radical scavenging assay, chelating effect of ferrous ion and total antioxidant capacity assay. Ethanolic fraction from the above mentioned edible mushroom was also tested for total phenol, flavonoid, β-carotene, lycopene and ascorbic acid content. Findings showed that most of the EC50 values were more than 2 mg /ml except DPPH radical scavenging test. The extract exhibited 50% DPPH radical scavenging activity at only 1.5 mg /ml concentration. Estimated putative antioxidant components was in order of phenol > ascorbic acid > flavonoids > β-carotene > lycopene. Result implies that P. cornucopiae can be a potential source of natural antioxidants which may be used as a food supplement to treat various oxidative stress related diseases.
