Alpha-Mangostin is one of the xanthones, besides beta-mangostin, garcinone E and B which are derived from the rind of mangosteen. Mangosteen is a tropical fruit grown in Southeast Asian countries. Since ages, the pericarp has been valued for its medicinal properties and has been used to treat conditions like bladder infections and diarrhoea. Studies show that Alpha-Mangostin and the other xanthones in mangosteen have anti-inflammatory, antifungal, antimicrobial, antiseptic as well as anti-cancerous effects. Besides xanthones, the therapeutic property of the fruit is also attributed to the presence of tannins in the rind. However, studies also suggest that high doses of Alpha-Mangostin may prove to be toxic.
