Oleanolic (glycoside)
This entry refers to a glycoside (saponin) of oleanolic acid, a pentacyclic triterpenoid widespread in plants.
Where Does It Come From? (2)
Oleanolic (glycoside) is a naturally occurring triterpenoid saponin (oleanolic acid glycoside), found in Calendula and Mullein. It is well tolerated orally (low toxicity).
Research & Evidence
This record corresponds to a glycoside of oleanolic acid — that is, an oleanane-type pentacyclic triterpenoid bearing attached sugar units, making it a triterpenoid saponin. Such oleanolic acid glycosides are common plant constituents and occur in herbs such as calendula and mullein. They share the general profile of dietary triterpenoid saponins and have been studied largely for antioxidant and anti-inflammatory activity in laboratory work. For the free aglycone, see the separate entry for oleanolic acid.
Toxicity & Safety
Oleanolic acid glycosides are widespread in edible and medicinal plants and are generally regarded as low in toxicity at dietary levels. They have not been individually characterised in detail for safety.
