3.4. Lipid Peroxidation Inhibition Activity
Inhibition of lipid peroxidation by the ethanolic extracts of various banana peels is represented in Figures 3(a)-(b). Lipid peroxides are unstable and decompose to form reactive carbonyl compounds responsible for DNA damage, generation of cancer and age related diseases [20]. Most abundant among them is malondialdehyde (MDA), which reacts with thiobarbituric acid (TBA) to form a pink chromogen [21]. The decrease in the MDA levels in the presence of increased concentration of each extract indicates the role of extracts as antioxidants. TBARS assay was used to determine the anti-lipid peroxidation properties of the banana peel extracts. The re-sult values obtained indicate a moderate percentage inhi-bition with Poovan peel extract exhibiting highest inhibi-tion among other varieties at 10 mg·ml–1.
