Abstract:  Study on the antioxidation of vegetable eggplant and“SAIJIN”,a health food,made of 14 different kind of vegetables.Method 27 Wister-rats were divided into 3 groups.They were fed with artificial semi-synthetic diet added with 6% eggplant freeze-drying powder(eggplant group)and 6%"SAIJIN"Powder ("SAIJIN" group)respectively,and control group fed with normal artificial semi-synthitic diet (pair fed).All rats were Killed after 45d.Blood,liver,kidney,brain and spleen were taken.The activities of SOD,CuZn-SOD,GSH-Px and the contents of MDA in serum and tissues were assayed.Result The activities of SOD and CuZn-SOD in rats’brain of eggplant group were significantly higher than that of control.The activity of CuZn-SOD in brain of "SAIJIN"group was higher than that of control too.However,the activity of CuZn-SOD in liver of both vegetable groups was lower than that of control.Contents of MDA in serum and liver of both vegetable groups were decreased obviously.The acivities of GSH-Px were of no difference among all groups.Conclusion Eggplant and health food "SAIJIN" could improve the activity of SOD to scavenge free radicals ,inhibit lipid peroxidation,reduce the content of malonic aldehyed and strengthen the antioxidation of body.
