Abstract: The effects of corn peptides(CP) on hemolysis of rats red blood cell were observed in the spectrophotometric method, while the reagent kits were used to analyze the content of malondialdehyde (MDA). In vitro, the inhibiting rate of 10.0mg/ml CP on radical-induced MDA formation in rat liver mitochondria was 39.63%, while 22.83% in normal rats liver, 45.59% incubated with Fe2+ and 67.53% incubated with H2O2. CP made the radical-induced swelling of rats liver mitochondria obviously be lower than the control, so the results showed that CP could inhibit oxidation damage of rats liver mitochondria. Cp could also inhibit hemolysis induced by H2O2 during warm-bathing of rats red blood cell, so this result showed activity the protection held against oxidation damage of rats red blood cell.
