Abstract
Abstract 5-Hydroxy- l -tryptophan (5-HTP) has been found in high concentration (6–10% fr. wt.) in the mature seeds of Griffonia simplicifolia , a West African legume of reputed physiological activity, and in lower concentration in other parts of the plant. An enzyme system capable of hydroxylating l -tryptophan has been identified in various tissues. 5-Hydroxytryptamine (5-HT or serotonin) has been found in concentrations of up to 0·2% (dry wt.) in the pods and in lower concentration in the leaves of mature plants. Indole-3-acetyl-aspartic acid (IAAA) and 5′-hydroxyindole-3-acetic acid (5-HIAA) were among other indoles detected.
