Facts and Food Sources of Indoles


Indole is an aromatic heterocyclic organic compound having C8H7N formula. It has bicyclic structure which consists of six membered benzene ring combined to a five membered pyrrole ring. It is distributed widely in natural environment and could be produced by various bacteria. Indole as an intercellular signal molecule, it regulates various aspects of bacterial physiology which includes spore formation, plasmid stability, resistance to drugs, virulence and biofilm formation.

It is used to make perfumes and tryptophan which is an essential amino acid and indoleacetic acid, a hormone enhancing development of roots in plant cuttings. Firstly, Indole was isolated in 1866 with molecular formula C8H7N. It is synthesized from pyruvic acid and phenylhydrazine though several other procedures are discovered. Moreover, indigo, tryptophan and indoleacetic acid are the various compounds that could be obtained from plant and animal sources containing indole molecular structure. Indole alkaloids are the best known group of compounds, the members of which is isolated from plants that represent more than 30 families. Psilocybin, psilocin, strychnine and reserpine belong to this group. Indole is a colorless solid with pleasant fragrance in highly dilute solutions. It melts at 52.5° C (126.5° F).
