What is Oleanolic aldehyde?

Plain description, key identifiers and synonyms

Oleanolic aldehyde is a pentacyclic triterpenoid and hydroxyaldehyde that is erythrodiol in which the primary hydroxy group at position 28 has been oxidised to the corresponding aldehyde. It is found in grapes and olives. It has a role as a plant metabolite. It is a pentacyclic triterpenoid, a secondary alcohol and a hydroxyaldehyde. It is functionally related to an erythrodiol. It derives from a hydride of an oleanane.
