Measurement of catecholamines and their metabolites

ACP Broadsheet No 127: April 1991. Measurement of catecholamines and their metabolites in urine.

Dopa, catecholamines and their metabolites in essential hypertension.

1. Urinary excretion of dopa, catecholamines and their metabolites (vanillylmandelic acid, methoxycatecholamines, 3-methoxy-4-hydroxyphenylglycol and homovanillic acid) were studied in eighty patients with essential hypertension and in twenty-five healthy control subjects. 2. Increased urinary excretion of catecholamines, dopa and catecholamine metabolites was found in a proportion of cases. 3....

Olfactory sensitivity to catecholamines and their metabolites in the goldfish.

The current study assessed the olfactory sensitivity of the goldfish (Carassius auratus L.) to the catecholamines, their immediate precursors and metabolites by use of the electro-olfactogram (EOG). The olfactory system of the goldfish was found to be sensitive to both adrenaline and dopamine with thresholds of detection of 10(-7.8) and 10(-7.9) M respectively, but less so to noradrenaline (thr...

Liquid-chromatographic measurement of catecholamines and metabolites in plasma and urine.

In this general method for measuring the concentrations of neurotransmitters in body fluids by "high performance" liquid chromatography (HPLC), the procedures for extracting different biogenic amines from body fluids vary, but the basic chromatographic conditions are the same for all. We use citric/formic acid buffer as the mobile phase, a C18 column, and an electrochemical detector. Specificit...
