The present study aims to evaluate the antioxidant potential of the green colored peel extracts of Citrus limon belonging to the family Rutaceae. The peel extracts in different solvents were investigated for their antioxidant activity using in vitro assays and the results were compared with the standard ascorbic acid. Determination of total phenolic and total flavonoid contents in these extracts were done using gallic acid and rutin/quercetin equivalents respectively. Radical scavenging activities were determined using DPPH assay and reducing power assay. The free radical scavenging and antioxidant activities may be attributed to the presence of phenolic and flavonoid compounds present in the extracts. The results in the present study indicated that Citrus limon peels serve as potential source of natural antioxidants which may suggested for the polyherbal formulations and drug designing for the treatment of various diseases and can be studied further.
