Preliminary Study on Antioxidation Effects of Chaenomeles sinensis Fruit Extracts

Abstract

Abstract: Objective:To study on the anti-oxidation effects and mechanism of Chaenomeles sinensis fruit extracts. Methods:Pyrogallol auto-oxidation method,Fenton reaction and DPPH methods were used to detect antioxidation properties in vitro,and the activity of supeioxide dismutase(SOD),malondialdehyde(MDA)in the serum,heart,liver and kidney and liver peroxidase(POD) of the mice administered with different doses of the extracts by gavage were measured in vivo. Results:The Chaenomeles sinensis fruit extracts have strong O2·,·OH and DPPH· radicals,scavenging activity. They have preventive effect on the rise of lipid peroxide and improve the SOD activity. The results suggested that pawpaw flavoind is a potential antioxidant and(POD) activiy.Conclusion:The extracts have excellent antioxotion properties.

Key words: Chaenomeles sinensis fruit extracts, antioxidation, SOD, POD, MDA
