Iridoids are a type of monoterpenoids in the general form of cyclopentanopyran, found in a wide variety of plants and some animals. They are biosynthetically derived from 8-oxogeranial. [1] Iridoids are typically found in plants as glycosides, most often bound to glucose.

环烯醚萜是一类有机物，属于单萜，具有易溶于水、甲醇，可溶于乙醇、丙酮和正丁醇，难溶于氯仿、乙醚、苯等亲脂性有机溶剂的性质。 在植物中通常与糖形成环烯醚萜苷，大部分为葡萄糖。 烯醚萜苷和裂环烯醚萜苷为白色结晶体或无定形粉末，多具旋光性、吸湿性，味苦。

Research has confirmed that iridoids exhibit promising anti-inflammatory activity which may be beneficial in the treatment of inflammation. Iridoids are secondary metabolites present in various plants, especially in species belonging to the Apocynaceae, Lamiaceae, Loganiaceae, Rubiaceae, Scrophulariaceae and Verbenaceae families.

Iridoids, a large and still expanding class of cyclopentane pyran monoterpenes, are composed of two basic carbon frameworks, substituted iridoids, and secoiridoids. They are more prevalent in the kingdom Plantae, especially in the dicotyledonous plants from Scrophulariaceae, Pyrolaceae, Oleaceae, Labiatae, Rubiaceae, and Gentianaceae [1, 2].

2013年1月1日 · Iridoids represent a special and interesting class of cyclopentan [c] pyran monoterpenoids. The name “iridoid” is a generic term derived from the names of compounds iridomyrmecin, iridolactone, and iridodial, which were isolated from the defense secretion of the species of Iridomyrmex, a genus of ants.
