Abstract

A method is presented for the precolumn derivatization and subsequent high-pressure liquid chromatographic separation of 3-methylhistidine from urine and plasma. The solvent system is 10 mm sodium phosphate (pH 7.5) and acetonitrile. The elution can be performed isocratically and requires less than 10 min. Both fluorescent and ultraviolet detection may be utilized. This method is at least 103 times more sensitive than conventional ion-exchange chromatography using ninhydrin. 3-Methylhistidine determinations performed on plasma and urine samples from normal volunteers correlated well with published literature values.
