摘要:

对米糠抗氧化肽体外抗氧化作用进行研究。结果显示,米糠抗氧化肽(0.32mg/mL)能够抑制血红蛋白氧化反应和红细胞溶血,抑制率为50% 左右,表明其对大鼠红细胞和血红蛋白的氧化损伤具有保护作用;米糠抗氧化肽能抑制红细胞及肝组织自氧化产生的MDA 和由H2O2 诱导产生的MDA,抑制率为41%~60%;并能抑制自由基诱导的大鼠肝组织匀浆中脂褐质的产生。

Abstract:

In this study, biological functions of rice bran antioxidant peptides were investigated. Results indicated that rice bran antioxidant peptides exhibited an effective scavenging capability to free radicals and inhibit peroxide reactions of hemoglobin and hemolysis of red blood cells (RBC); moreover, rice bran antioxidant peptides also revealed an excellent inhibition effect on MDA generated from RBC, liver tissue and H2O2 oxidation system. Furthermore, rice bran antioxidant peptides also could suppress the generation of lipofasci from liver tissues induced by H2O2.

Key words: rice bran antioxidant peptide, antioxidation, in vitro
