本文以红细胞为对象探讨了马桶花AB—2的抗氧化作用。用叔丁基过氧化物(butylhydnperoxide)为氧化剂使红细胞氧化,加马桶花AB—2后不仅可使红细胞膜脂质的氧化物减少,又可保护膜蛋白的巯基不致氧化聚合。马桶花AB—2可防止血红蛋白的自氧化及溶血,用电子自旋捕集法测羟自由基,结果说明马桶花AB—2可直接与羟自由基反应,可能是自由基的清除剂。
This article discusses the antioxidation of AB-2 in toilet flower using red blood cells as the object. Oxidation of erythrocytes with butylhydoxide as an oxidizing agent can increase not only the oxides of lipids in the erythrocyte membrane but also the thiol groups of the membrane proteins without oxidative polymerization. Toilet flowers AB-2 can prevent hemoglobin from autoxidation and hemolysis. The use of electron spin trapping method to measure hydroxyl radicals, the results show that toilet flowers AB-2 can directly react with hydroxyl radicals, may be a free radical scavenger.
