Abstract: Objective: To study the effect of plant oils containing DHA algae oil on free radical metabolism (MDA), total antioxidant capacity (T-AOC) and catalase (CAT) in the cerebral cortex of SD rats.Methods:60 SD male rats were randomly divided into 10 groups: negative control group, namely the normal diet group (CK1, CK3the same below);positive control group, namely pure DHA group (CK2,CK4 the same below);DHA soybean oil: low, medium, high dose group;DHA peanut oil: low, medium and high dose group. Take different doses of DHA soybean oil, DHA peanut oil to feed the rats for 4 weeks,after the experiment,measure the MDA content, T-AOC, CAT activity of the rat brain tissue.Conclusion: Compared with the control group CK1,DHA soybean oil and DHA peanut oil can significantly reduce the content of MDA in brain tissue, improve the activity of T-AOC and CAT,which can help to enhance the bodys free radical scavenging and reduce lipid peroxidation injury.In the DHA soybean oil group ,there is a significant difference between high dose group and negative control group,while there is no significant difference between high dose group and positive control group ,so we chose the high dose group whice pure DHA conten si 750mg / (kg·d) as the best effect.And in DHA peanuts oil, high dose group compared with the negative control group CK3, MDA, T - AOC differences were very significant, CAT significant difference, compared with the positive control group CK4, MDA, T - AOC were no significant difference , so choose hig
