Abstract
BackgroundIn the present study, the lemon pulp and peel along-with their secondary metabolites were studied and compared for its antioxidant activity. MethodVarious in vitro and ex vivo studies were done to estimate the polyphenols and flavonoids present in the lemon pulp and peel. The reducing power, free radical scavenging activity and lipid peroxide inhibition were investigated for the extracts. ResultsThe lemon peel was found to have a slightly greater count of polyphenols and flavonoids, showing a difference of 0.2. The peel extracts also showed better reducing power and higher free radical scavenging activity. The peel extracts gave 82.3% of inhibition towards lipid peroxidation, when compared to the pulp extracts which showed an inhibition of 78.2%. ConclusionThe antioxidant activity was found to be higher in the case of lemon peel when compared to the pulp.
