蔬菜类食品“赛金”与茄子抗氧化作用的研究

摘要/Abstract

摘要： 目的观察蔬菜类食品“赛金”和典型的茄果类蔬菜-茄子的冷冻干燥粉对生长中大鼠体内的抗氧化功能的影响。方法饲料中分别添加6%的“赛金”和茄子的冷冻干燥粉,设置对照组,饲喂45天后断头处死,取血及肝、脑、脾、肾等组织,分别测定血清及组织匀浆液中的SOD和CuZn-SOD活性、MDA含量以及组织匀浆中的GSH-Px活性。结果茄子组大鼠脑组织中SOD活性显著高于对照组;“赛金”和茄子组动物脑组织中CuZn-SOD水平均显著高于对照组,肝脏中CuZn-SOD活性则显著低于对照组。“赛金”和茄子组大鼠血清中的MDA水平均明显低于对照组;茄子组动物肝脏中的MDA含量也明显低于对照组。GSH-Px活性各组间有显著差异。结论蔬菜食品“赛金”和茄子能够提高SOD灭活氧自由基的能力,抑制脂质过氧化,降低丙二醛含量,改善机体的抗氧化能力。

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.
