Mass fragmentographic determination of vanilmandelic acid, homovanillic acid and Isohomovanillic acid in human body fluids
J Chromatogr 1978 Jan 1;145(1):1-9.PMID:621233DOI:10.1016/s0378-4347(00)81663-1.
Vanilmandelic, homovanillic and isohomovanillic acids in body fluids were efficiently isolated by liquid chromatography on an Amberlite XAD-4 column and by organic extraction in a special apparatus. The purified metabolites were converted into their trifluoroacetylhexafluroisopropanol esters and analyzed by mass fragmentography. The working curves of the metabolites were linear from 0.5 to 5 ng injected. The minimum detectable concentrations of all the metabolites were 2 ng/ml for plasma and cerebrospinal fluid, and 120 ng/ml for urine. The metabolite concentrations in plasma, cerebrospinal fluid and urine of normal persons and patients were determined.
Determination of the biogenic amines and their major metabolites in single human brain tissue samples using a combined extraction procedure and high-performance liquid chromatography with electrochemical detection
J Chromatogr 1985 Nov 29;345(1):33-42.PMID:4086586DOI:10.1016/0378-4347(85)80132-8.
A combined extraction system for the selective and quantitative isolation of the monoamines norepinephrine, epinephrine, dopamine, serotonin (5-hydroxytryptamine) and their metabolites 3-methoxy-4-hydroxyphenylethylene glycol, 3,4-dihydroxyphenylacetic acid, 5-hydroxyindoleacetic acid, homovanillic acid and 3-methoxytyramine from one single brain tissue sample is described. The extraction system is a combination of an ethyl acetate extraction for 3-methoxy-4-hydroxyphenylethylene glycol, 3,4-dihydroxyphenylacetic acid, 5-hydroxyindoleacetic acid and homovanillic acid, and two successive ion-pair extractions. In a first step, the catecholamines are quantitatively isolated by extracting with heptane--octanol (99:1) containing 0.25% tetraoctylammonium bromide as an ion-pairing agent in the presence of 0.2% diphenylborate. In a second step, 3-methoxytyramine and 5-hydroxytryptamine are isolated from the aqueous phase with di(2-ethylhexyl)phosphoric acid as counter-ion in chloroform. Dihydroxybenzylamine, Isohomovanillic acid and 5-hydroxy-N-methyltryptamine are used as the internal standards.
