The aril is the flavorful part of the fruit but, when analyzed specifically for its nutrient content, the mangosteen aril only meets the first criterion above, as its overall nutrient profile is absent of important content.
Some mangosteen juice products contain whole fruit purée or polyphenols extracted from the inedible exocarp (rind) as a formulation strategy to add phytochemical value. The resulting juice has purple color and astringency derived from exocarp pigments, including xanthones under study for potential anti-disease effects. The potential health benefits of xanthones were debated in a four-part series in 2009.
Other authors proposed that alpha-mangostin, a xanthone, could stimulate apoptosis in leukemia cells in vitro.
Furthermore, a possible adverse effect may occur from chronic consumption of mangosteen juice containing xanthones. A 2008 medical case report described a patient with severe acidosis possibly attributable to a year of daily use (to lose weight, dose not described) of mangosteen juice infused with tannins.
