Skatole, or 3-methylindole, is a foul-smelling constituent of mammalian feces; it is produced by the decomposition of tryptophan in the digestive tract. It has a floral aroma at low concentrations, contributing to the pleasant smell of flowers such as jasmine and orange blossoms. Skatole also occurs naturally in substances as diverse as beetroot and coal tar.
