Research Area: Inflammation Biological Activity: Oleanolic acid(Caryophyllin) is a naturally occurring triterpenoid, widely distributed in food and medicinal plants, related to betulinic acid. It is relatively non-toxic, antitumor, and hepatoprotective, as well as exhibiting antiviral properties. An extremely potent synthetic triterpenoid analogue of oleanolic acid was found in 2005, which are powerful inhibitors of cellular inflammatory processes. [1]
