Introduction：

正式测定前务必取2-3个预期差异较大的样本做预测定                                             

测定意义：

超氧阴离子自由基作为生物体代谢过程中产生的一种自由基，可攻击生物大分子，如脂质、蛋白质、核酸和聚不饱和脂肪酸等，使其交链或者断裂，引起细胞结构和功能的破坏，与机体衰老和病变有很密切的关系，清除超氧阴离子自由基的研究已经得到了广泛的关注。

测定原理：

AP-TEMED系统产生超氧阴离子，与盐酸羟胺反应生成NO2－，NO2－与对氨基苯磺酸和α－萘胺的作用生成红色的偶氮化合物，在530nm处有特征吸收峰，样品对超氧阴离子的清除能力与530nm的吸光值呈负相关。
