Technical information about 'Iridoids'

Definition: A type of MONOTERPENES, derived from geraniol. They have the general form of cyclopentanopyran, but in some cases, one of the rings is broken as in the case of secoiridoid. They are different from the similarly named iridals (TRITERPENES).

Registry Number: 0

Descriptor UI: D039823

Alternative terms: Iridoids; Secoiridoid Glucosides; Glucosides, Secoiridoid; Secoiridoids; Iridoidglucosides; Iridoid Glucosides; Glucosides, Iridoid;
