Xanthones, which are unique to the Mangosteen, as a class of phytonutrients are polyphenolic bioflavonoids. Over 60 research papers show antitumor, antiproliferative, antimicrobial, antihistamine, antiflammatory, antioxidant and gastrointestinal protective effects.

Proanthocyanidins present in the Mangosteen as in grape seeds and skins and pine bark extract, have numerous qualities considered to be valuable in both the prevention of disease and the restoration of homeostasis (healthful balance) when disease is present. Hundreds of papers document the antitumor, antiproliferative, antimicrobial, antioxident and neuroprotective effects of proanthocyanidins.

Catechins are active ingredients in green tea as well as Mangosteen. Hundreds of papers detailing the benefits of catechins exist. They document antitumor, antimicrobial, antioxidant, anti-inflammatory and neuroprotective effects.

Polysaccharides known to have beneficial health effects, are very plentiful in the Mangosteen. Since the molecular footprint of the fruit has not yet been traced, we cannot, at this time, specify which polysaccharides are in the plant.
