Abstract:The extractions of pericarp of Yongchun citrus by alcohol, aether and ethyl acetate was studied. Extracts were added to lard and peanut oil to determine the POV values in different conditions. Results showed that all extracts from pericarp of Yongchun citrus by different solvents have anti-oxidation effects. In lard, extract by ethyl acetate showed better antioxidant effect than those extracted by other solvents. However, in arachis oil, the antioxidant effect of extract by alcohol was better than those by other solvents. Extracts by ethyl acetate had the best heat resistance in all three extracts after high temperature process.
