Ascorbic acid stability was studied under conditions of dehydroascorbic acid assay. The minimum amounts of cysteine and volumes of reagents utilized were specified. Based on the data of 2,6-dibromoindophenol stability the method of indophenol-xylol extraction was proved to be unsatisfactory for the assay of dehydroascorbic acid.
在脱氢抗坏血酸测定条件下研究了抗坏血酸的稳定性。规定了所用半胱氨酸的最小量和试剂体积。根据2,6 - 二溴靛酚稳定性的数据，证明靛酚 - 二甲苯萃取法不适用于脱氢抗坏血酸的测定。
