„A microdilution technique for the assessment of in vitro activity against Entamoeba histolytica was devised and validated with metronidazole. The test was used to detect the antiamoebic activities of plant extracts prepared from the traditional remedies Brucea javanica fruits and Simarouba amara stems. The activity was associated with quassinoid-containing fractions. The 50% inhibitory concentrations for some quassinoids against amoebae were determined by using the microdilution method. These concentrations ranged from 0.019 for bruceantin, the most active quassinoid, to greater than 5 for glaucarubol, the least active compound tested.“

„Brucea javanica has demonstrated a variety of antitumoral, antimalarial, and anti- inflammatory properties. As a Chinese herbal medicine, Brucea javanica is mainly used in the treatment of lung and gastrointestinal cancers. Pharmacological research has identified the main antitumor components are tetracyclic triterpene quassinoids… Traditionally, Brucea javanica has been used to treat amebic dysentery… Clinical research indicates that infusion of Brucea javanica can be used to treat vulvar condylomata, with numerous advantages, including a rapid onset of action, convenience, low toxicity, and minimal irritation of the mucosal skin. “
