mangosteen-01Treatment of hepatocellular carcinomas (HCCs) with chemotherapy has generally been disappointing and it is most desirable to have more effective new drugs.

We extracted and purified 6 xanthone compounds from the rinds (peel) of the fruits of Garcinia mangostana L., using partitioned chromatography and then tested the cytotoxic effects of these compounds on a panel of 14 different human cancer cell lines including 6 hepatoma cell lines, based on the MTT method.

Several commonly used chemotherapeutic agents were included in the assay to determine the relative potency of the potential new drugs. Our results have shown that one of the xanthone derivatives which could be identified as garcinone E has potent cytotoxic effect on all HCC cell lines as well as on the other gastric and lung cancer cell lines included in the screen.

We suggest that garcinone E may be potentially useful for the treatment of certain types of cancer.
The Xanthones from the mangosteen have been shown in laboratory studies to be powerful Antioxidants, Anti-Inflammatories and to have other special properties. However, laboratory results do not guarantee that the same will happen in the human body. Mangosteen is a nutritious fruit not a drug, and no therapeutic claims are made for this product.
