Abstract

A simple procedure for the simultaneous determination of major metabolites of dopamine and serotonin in plasma, i.e. 3,4-dihydroxyphenylacetic acid, 5-hydroxyindole-3-acetic acid, and 4-hydroxy-3-methoxyphenylacetic acid, was developed. The method is based on rapid isolation of the compounds by one-step clean-up on a small C18 column, followed by high-performance liquid chromatography with dual electrochemical detection. The system is readily used for clinical applications.
