A method for the assay of dehydroascorbic acid using high-performance liquid chromatography with uv detection is described. The dehydroascorbic acid is separated from ascorbic acid and reduced with dithiothreitol, and is then quantitated as ascorbic acid following rechromatography. Since as little as 22 pmol can be detected, sensitivity is at least 40-fold greater than that of other currently available procedures. This method was used to measure the level of dehydroascorbic acid in normal and chronic lymphocytic leukemia lymphocytes. A significantly higher concentration of dehydroascorbic acid was found in leukemic (21.80 ± 3.55 nmol 108cells , mean ± SE) than in normal lymphocytes (9.32 ± 1.15 nmol 108cells ) (P < 0.03). Analysis of extracts from normal B cell lymphocytes revealed comparable dehydroascorbic acid levels to unfractionated lymphocytes, indicating that the elevated level in chronic lymphocytic leukemia was not simply a reflection of the increased percentage of B lymphocytes in this disorder. These studies illustrate that the technique can be used to measure the dehydroascorbic acid content from sources where only scanty material is available or low levels are found.
