Über das Verhalten von Adrenalin und Noradrenalin im Blut

Abstract

After infusion of Adrenaline or Koradrcnaline on cats these two amines have been determined chemically in the blood. Both of them decrease rapidly with half lives of about 25 seconds. The decrease is partly attributed to transmethylation.

The Chemistry Of Adrenochrome And Related Compounds

“…The basic procedure has been adapted to the differential determination of mixtures of adrenaline and noradrenaline, e.g., the addition of sodium thiosulfate to acid solutions of the catechol amines prior to the condensation inhibits the formation of the fluorescent derivative from noradrenaline (166). As in the case of the "lutin" method the excitation and fluorescence spectra of the two condensates are sufficiently different to permit a quantitative differentiation to be made (134,184,200).…”

Fluorometric Analysis

“…The fluorometric determination of adrenaline and noradrenaline in plasma and urine has been investigated extensively by Weil-Malherbe and Bone (186,187) and by Euler and Floding (52). Other papers on the determination of these substances in plasma (87,157,184), and in urine (70,149) have appeared. Because of the possibility of forming more than one fluorescent product, controlled conditions in this determination are important (25).…”
