摘　　要：提出对《茜素紫光度法检测H2O2/Co2+产生的羟自由基》一文中自由基清除率计算公式的修改,并探讨公式适应范围。实验发现该文中的公式有疏忽,按原公式计算结果和其他文献对相同物质维生素C清除羟自由基的结果有差异。故对原公式提出修改,并提出有颜色的抗氧化剂适用公式。We suggested that the clearance formula of scavenging hydroxyl radical should be modified in the paper Assay of hydroxyl radical produced by H_2O_2/Co^(2+) reaction using alizarin violet spectrophotometry.It was found in use of this formula that the clearance of hydroxyl radical by vitamine·C was much different from the result reported in other paper,it was sure that some carelessness existed in the original formula.Therefore,we modified the original formula and at the same time proposed a new formula for the medicament of anti-oxidation with color.
