The urinary metabolites of epinephrine (EPI) and norepinephrine (NOR) after intravenous injection in the chicken were predominantly 0-methylated in the form of 3-metimoxy-4-hydroxy phenyl glycol and 3-methoxy-4-hydroxy mandelic acid. EPI and NOR administered into the venous renal portal circulation were actively transported in their original form as aminated, free catechols as evidenced by column and paper chromatography.
