ABSTRACT
Plasma 3-O-methylated catecholamines, i.e. 3-methoxytyramine, normetanephrine and metanephrine, were separated from catecholamines by passing through alumina and further purified by adsorbing on weakly acidic resin and Amberlite XAD-4. The amines were trifluoroacetylated and determined by gas chromatography or mass fragmentography. Tracer quantities of tritiated 3-MT, NMN or MN were used as internal standards for total recovery estimations. The contents of 3-O-methylated catecholamines in the plasma of normal persons and patients with hyperthyroidism, hypertension, neuroblastoma and pheochromocytoma were measured.
