Abstract

TRYPTAMINE is a normal constituent of human urine1–5; about 30–120 µg of the amine are excreted per 24 h. In blood, tryptamine has hitherto been demonstrated only qualitatively and under pathological conditions in a carcinoid patient6. There is no information about an occurrence of N,_N_-dimethyltryptamine in human beings. N,_N_-dimethyl-5-hydroxytryptamine (= Bufotenin) was demonstrated qualitatively as a constituent of normal human urine4,7; in children an excretion of 0–0.03 µg amine/100 mg creatinine has been found with, at most, semi-quantitative methods4. Apparently, N,_N_-dimethyl-5-hydroxytryptamine was still not demonstrated in blood. 5-Methoxytryptamine has been found in the urine of patients with rheumatic fever8, and that in an order of magnitude of 30–210 µg/24 h.
