Gas Chromatographic Estimation of Homovanillic Acid in Serum of Normals and Psychotic Patients

Abstract: Summary: Homovanillic acid is extracted from 0.5 ml serum with ethyl acetate at acidic pH, and its pentafluoropropionic anhydride and hexafluoroisopropanol derivative injected into a 3% SE-30 column at 140 °C, fitted with an electron capture detector. In a group of normal volunteers (n = 42) a mean value of 62 ± 45 jug/1 was found. The distribution of the serum concentrations was found to be bimodal. Using the same procedure for the homovanillic acid estimation in cerebrospinal fluid (CSF), mean values of 73.0… Show more

“…The high precision and accuracy of the present HPLC method are due to the sensitivity and relative specificity of electrochemical detection, very simple sample preparation and the use of a "tailor made" internal standard with physicochemical properties very close to the analyte, HVA. Previously, only gas chromatographic procedures with either electron capture (Markianos & Ruther 1976;Markianos & Beckmann 1876) or mass spectrometric (Anggard et al 1973;Bacopoulos et al 1979;Muskiet et al 1980;Burns et al unpublished results) detection have been available. The former have yielded too high estimates of the normal range of concentrations of HVA in human plasma, while the latter are out of reach for most clinical and research laboratories due to their high cost and technical complexity.…”
