Abstract:
Objective: To investigate the free radical scavenging activities of the extract from pomegranate peel and compare with that from juice. Methods: Free radicals (-2O, 稯H and ROO? scavenging activities were investigated in different special chemical systems. Its inhibition activity on LDL oxidation was studied with LDL oxidation model in vitro. Results:Both extracts had strong abilities to scavenge -2O, 稯H and ROO?radicals and prevent LDL oxidation in dose-dependent manner. The extract from peel showed higher activities than that from juice. Conclusion: The natural antioxidants in the extracts of pomegranate peel or juice can effectively scavenge -2O, 稯H and ROO?radicals, and prevent LDL oxidation significantly, especially much more in the former.
