The urinary excretion patterns of the serotonin (5-hydroxytryptamine; 5-HT) metabolites 5-hydroxyindole-3-acetic acid (5-HIAA) and 5-hydroxytryptophol (5-HTOL) were examined after ingestion of bananas, a food rich in 5-HT. The bananas contained on an average 25 micrograms 5-HT/g pulp. Both urinary
A simple method is described for the simultaneous determination of vanilmandelic acid (VMA), 3,4-dihydroxyphenylacetic acid (DOPAC), 5-hydroxyindole-3-acetic acid (5-HIAA) and homovanillic acid (HVA) in urine. The compounds are isolated by a one-step sample clean-up on Sephadex G-10, separated by
The urinary excretion products of serotonin (5-hydroxytryptamine, 5HT) are 5-hydroxyindole-3-acetic acid (5HIAA) and 5-hydroxytryptophol (5HTOL), and the ratio of 5HTOL to 5HIAA is normally very low (< 0.01 ) in man. Intake of foods rich in 5HT (high amounts in banana, pineapple, and walnuts)
