✦ Synopsis

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 oxalate was 100.2 + 6.65% (mean and SD). The precision of the method at two concentrations was 30.65 f 0.67 (SD) and 39.3 + 2.3 (SD) mg/liter and the mean result on 23 normal volunteers was 36.0 + 9.7 (SD) mg/day. I
