ABSTRACT Fractionation of monkey pituitary glands gave an oxytocin fraction in low yield which showed a counter-current distribution coefficient equivalent to that obtained with oxytocin from other species. Fractionation and chromatography of monkey vasopressin on carboxymethyl cellulose gave arginine-vasopressin of 60% purity, based on amino acid analysis and specific activity. Counter-current distribution on a small scale gave arginine-vasopressin of 89% purity. Reports by others that monkey pituitary glands contain arginine-vasopressin, based on pharmacological activities, are substantiated by the chemical data presented here.
