  • Title: Assay of 4-hydroxy-3-methoxyphenylacetic (homovanillic) acid by liquid chromatography with electrochemical detection.
    Author: Morrisey JL, Shihabi ZK.
    Journal: Clin Chem; 1979 Dec; 25(12):2045-7. PubMed ID: 509705.
    Abstract:
    We describe a method for the assay of urinary 4-hydroxy-3-methoxyphenylacetic acid (homovanillic acid), based on its separation on a microparticulate reversed-phase column and direct electrochemical detection. Patients with neuroblastoma, pheochromocytoma, and Parkinson's disease have increased amounts of this compound in their urine.
