In addition, Ho et al. (2002) found that the garcinone E (Figure 2.19),
xanthone which extracted from mangosteen fruit pericarp has a potent
cytotoxic effect on heptocellular carcinoma cell lines. Garcinone E also
had shown cytotoxic effects against other cancer cell lines such as NCIHUT
125 lung carcinoma cell lines and AGS gastric carcinoma cell lines.
