The molecule is a pentacyclic triterpenoid that is oleanane containing a double bond between positions 12 and 13, and is substituted by hydroxy groups at the 3beta and 24-positions, and by an oxo group at position 22. It is a pentacyclic triterpenoid and a cyclic ketone. It derives from a hydride of an oleanane.
