Isolated from the leaves and twigs of Fatsia polycarpa, it exhibits antibacterial and anti-HBV activities. It has a role as a metabolite, an anti-HBV agent, an antibacterial agent and a plant metabolite. It is a hydroxy monocarboxylic acid, an ether and a pentacyclic triterpenoid. It derives from a hydride of an oleanane."}]
