Knowledge: Mangosteen Peel (Garcinia mangostana)

Mangosteen Peel Extract  (Garcinia Mangostana Extract)

Mangosteen, Garcinia mangostana L., is known as the “Queen of fruits” in Asia and can be cultivated in the tropical rainforest such as Malaysia, Indonesia, and Thailand. The purple ripe fruits consist of 6-8 seeds, and have a white and juicy pulp. Normally, people just eat the sweet pulp and throw away the purple peel.

However, studies found out that mangosteen peel is also useful, and the peel even contains more antioxidant than the pulp. Mangosteen extracts and purified constituents have been subjected to a wide array of biological tests particularly to infectious diseases, cancer chemotherapy and cancer chemoprevention, diabetes, and neurological conditions.

Compounds isolated from the fruit peel of mangosteen contain abundant xanthones, for example: α-mangostin, β-mangostin, γ-mangostin, gartanin, 8-deoxygartanin, and mangostanol. α-mangostin represents the majority of the clinical benefits of this plant, therefore determination of the concentration of α-mangostin as a chemical marker to quality control of G. mangostana and its products is usually done and marked in labels. Nowadays, mangosteen extract is also popularly applied to cosmetic and pharmaceutical products.
