Asiatic acid is a pentacyclic triterpenoid that is ursane substituted by a carboxy group at position 28 and hydroxy groups at positions 2, 3 and 23 (the 2alpha,3beta stereoisomer). It is isolated from Symplocos lancifolia and Vateria indica and exhibits anti-angiogenic activity. It has a role as an angiogenesis modulating agent and a metabolite. It is a monocarboxylic acid, a triol and a pentacyclic triterpenoid. It derives from a hydride of an ursane.
