Abstract
By using the permanganate method, noradrenaline and adrenaline contents of suprarenal extracts in pigs, goats, dogs, cats and rabbits were assayed. It was estimated that the relative amount of noradrenaline in the suprarenals was 43 (30-52) per cent of the total active substances in pigs, 36.5 (21-68) per cent in goats, 18.5 (7-29) per cent in dogs, 45.1 (38-53) per cent in cats and 1.8 (0-11) per cent in rabbits, respectively.
My thanks are due to Prof. T. Suzuki for his advice given during the course of this work.
