Abstract

Objective: To study the scavenging effects on hydroxyl radical (·OH), superoxidized anion radical (O2 ·) and malondialdehyde (MDA) generated by lipidperoxidation of different apple polyphenol extracts. Methods: The DR spectro- photometry and improved TBA spectrophotometry and solvent box method were used to determined the scavenging effects on· OH, O·2and MDA. Results: Different apple polyphenol extracts all had antioxidant effects, but in different antioxidant systems, different apple polyphenol extracts had different antioxidant effects, and the antioxidant effects of AP I and AP II showed better. Conclusion: Apple polyphenol extracts had antioxidant activity. The main antioxidant components were phenols and proanthocyandins oligomer with low molecular weight.
