Abstract: A ninhydrin-orthophthalaldehyde reagent for the determination of Nτ-methylhistidine has been developed. The sensitivity of the reagent is similar to that of ninhydrin. Since most amino acids are not detected by the reagent, this allows the determination of Nτ-methylhistidine in the presence of high concentrations of other amino acids. The reagent has been successfully used for the analysis of Nτ-methylhistidine in human urine.
