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，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。 在弱碱性条件下，邻苯三酚能发生自氧化反应产生超氧阴离子和有色中间产物，该中间产物在 320nm 处有特征吸收峰。当加入超氧阴离子清除剂时，它能迅速与超氧阴离子反应从而阻止中间产物的积累，使溶液在 320nm 处光吸收减弱。故可以通过测定A₃₂₀值来评价清除剂对超氧阴离子的清除能力。
Superoxide anion radical, a type of free radical produced during biological metabolism, can attack biological macromolecules, leading to the disruption of cellular structure and function. It is closely associated with organismal aging and pathological changes, making research on scavenging superoxide anion radicals widely recognized. Under weak alkaline conditions, pyrogallol undergoes autoxidation to generate superoxide anions and colored intermediate products. These intermediates exhibit a characteristic absorption peak at 320 nm. When a superoxide anion scavenger is added, it rapidly reacts with the superoxide anions, preventing the accumulation of intermediate products and thereby reducing the light absorption of the solution at 320 nm. Thus, the scavenging capacity for superoxide anions can be evaluated by measuring the absorbance at 320 nm (A₃₂₀).
