What part of the fruit is used for medicinal preparations?
The mangosteen fruit is comprised of the following three components: the pericarp – or rind, the pulp – which is the sweet segmented interior of the fruit, and the seeds – found inside the pulp. Xanthones and polysaccharides, which are the medicinal attributes, are found in highest concentrations in the pericarp of the mangosteen fruit. They are also found in the pulp but in lower concentrations. Due to the high concentrations of Xanthones and polysaccharides in the pericarp, it is incredibly important that any preparation include it in its reactive stage.
