| Common Name | Gambogic acid |

| Description | Gambogic acid, also known as gambogate or b-guttiferin, belongs to the class of organic compounds known as pyranoxanthones. These are organic aromatic compounds containing a pyran or a hydrogenated derivative fused to a xanthone ring system. Gambogic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Gambogic acid is a xanthonoid that is derived from the brownish or orange resin from Garcinia hanburyi. Outside of the human body, gambogic acid has been detected, but not quantified in, fruits and herbs and spices. This could make gambogic acid a potential biomarker for the consumption of these foods. At the highest level of 120 mg/kg the primary toxic target organs were the liver and kidneys. For the same length of exposure, the higher the concentration of gambogic acid that was administered, the greater the effect on inhibiting cell growth. Gambogic acid is found in Garcinia hanburyi. The ratio of relative tumor volume (RTV) for the treated group of mice to the control group indicates the gambogic acid was having an impact on tumor size while having no adverse effects on body weight or mortality. |
