It is found in the bark and other plant parts of several species of plants including Syzygium claviflorum. It exhibits anti-HIV, antimalarial, antineoplastic and anti-inflammatory properties. It has a role as an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor, an anti-HIV agent, an antimalarial, an anti-inflammatory agent, an antineoplastic agent and a plant metabolite. It is a pentacyclic triterpenoid and a hydroxy monocarboxylic acid. It derives from a hydride of a lupane."}]
