Isolated from the whole plants of Geum japonicum, it exhibits activity against HIV-1 protease. It has a role as a metabolite and a HIV protease inhibitor. It is an oxo monocarboxylic acid, a diol, a pentacyclic triterpenoid and a secondary alpha-hydroxy ketone. It derives from a hydride of an ursane."}]
