摘要

Aim: The present study was aimed at investigating the antioxidant activities of the leaves, fruits and peel extracts of Citrus aurantium, Citrus limetta and Citrus limon belonging to the family Rutaceae. Materials and Methods: The antioxidant activities of the hydroethanolic extracts have been evaluated by using different in vitro assays and the results were compared with the standard antioxidants such as butylated hydroxytoluene (BHT), ascorbic acid, curcumin, quercetin, etc. In addition, total phenolic and flavonoid contents in these extracts were determined as pyrocatechol and quercetin equivalents respectively. Among the extracts assayed, 4 extracts (leaf and peel extracts of C.aurantium , peel and fruit extracts of C.limetta ) had effective H donor ability, reducing power ability, metal chelating activity, superoxide anion radical, nitric oxide radical and hydroxyl radical scavenging activities. The antioxidant activity depends upon concentration and increased with increasing amount of the extracts. The free radical scavenging and antioxidant activities may be attributed to the presence of phenolic and flavonoid compounds present in the extracts. Result: The results obtained in the present study indicate that the leaves, fruits and peel of Citrus aurantium, Citrus limetta and Citrus limon serve as the potential source of natural antioxidants.
