Xanthone is a tricyclic compound made up of two benzene rings linearly fused to each other through a pyran ring that carries a ketone group.
Studies reported that garcinone E one of six xanthones from mangosteen pericarp had potent cytotoxic effect on all hepatocellular carcinomas cells lines as well as on the other gastric and lung cancer (Ho, C., Huan, Y., Chen, C. 2002 Planta Med. 68, pp 975-979)
