Oleanolic acid can be found in olive oil, Phytolacca americana (American pokeweed), and Syzygium spp, garlic, etc. It was first studied and isolated from several plants, including Olea europaea (leaves, fruit), Rosa woodsii (leaves), Prosopis glandulosa (leaves and twigs), Phordendron juniperinum (whole plant), Syzygium claviflorum (leaves), Hyptis capitata (whole plant), Mirabilis jalapa and Ternstromia gymnanthera (aerial part). Other Syzygium species including java apple (Syzygium samarangense) and rose apples contain it.
An extremely potent synthetic triterpenoid analog of oleanolic acid was found in 2005, that is a powerful inhibitor of cellular inflammatory processes. They work by the induction by IFN- of inducible nitric oxide synthase (iNOS) and of cyclooxygenase 2 in mouse macrophages. They are extremely potent inducers of the phase 2 response (e.g., elevation of NADH-quinone oxidoreductase and heme oxygenase 1), which is a major protector of cells against oxidative and electrophile stress.
A 2002 study in Wistar rats found that oleanolic acid reduced sperm quality and motility, causing infertility. After withdrawing exposure, mice regained fertility and successfully impregnated female mice.
