[Objective] The aim was to study on the oxidation resistance of flavonoids in Chinese jujube stone.[Method] The extract of flavonoids from Chinese jujube stone was added to fresh rapeseed oil and lard to explore the oxidation resistance of flavonoids;the removal rates of it to O2-·,DPPH· and ·OH were also studied.[Result] The flavonoids from Chinese jujube stone had good oxidation resistance on rapeseed oil and lard,and the effects showed dose-dependent;citric acid and vitamin C appeared synergistic effects...
