A procedure for the estimation of oxalic acid in urine based upon its quantitative reaction with 1,2-diaminobenzene and subsequent estimation of the quinoxaline by reverse-phase highperformance liquid chromatography has been developed. The method has given good reproducibility; recovery of added oxa

High-performance liquid chromatography (HPLC) monitoring with an ultraviolet detector was carried out to measure urinary oxalate levels in urolithiasis. Interfering substances in urine were removed by anion exchange prior to chromatography. This procedure was found excellent with respect to sensitiv
A high-performance liquid chromatographic (HPLC) method was developed to determine the levels of oxalic acid in the urine. This acid was extracted from urine with tri-n-butyl phosphate and converted into the fluorescent derivative by esterification with 9-anthryldiazomethane (ADAM). The reaction mix
