Catecholamines in a living body fluid are analyzed by a process comprising: reacting a living body fluid sample with a boron compound of the formula, <CHEM> wherein R is hydroxyl, aryl or alkyl, to form a complex of the boron compound with a catecholamine, deproteinizing the reaction solution containing the complex, and quantitatively determining the complex. The process makes it possible to measure catecholamines with a high recovery ratio and high accuracy, since catecholamines in a living body sample such as plasma, urine, etc., can be made insusceptible to the influence of the other substances in the living body samples, e.g. oxidation, by forming the catecholamines into a complex with a boron compound. |
