Bacteria. Polysaccharides from the pericarps of mangosteen, Garcinia mangostana Linn., mangosteen fruit, were extracted from the dried ground pericarps of the mangosteen fruit. The results showed that the number of S. enteritidis (bacteria) in cultured monocyte with extract of the pericarp of the mangosteen fruit was killed.
This paper showed that polysaccharides in the extract can stimulate phagocytic cells to kill intracellular bacteria (S. enteritidis).

A Summary of 31 Mangosteen Studies
Introduction: Narace D. Seudeal, Ph.D. is a Ph.D. in Clinical Biochemistry who refuses to accept products without the research to back them up — meaning actual clinical and scientific studies rather than weak tests that have no real relevance to the human condition. Mangosteen xanthones research is extensive and studied by Ph.D.’s, MD’s, and other research scientists from around the world.
Dr. Seudeal reviewed 31 selections of mangosteen xanthones research articles and condensed the main conclusions in an easy-to-read format with the least technical jargon as possible, yet keeping the integrity of the medical findings intact.
Remember, this is just a sampling of xanthones research. There are over 1500 papers on xanthones listed at, the National Medical Library. For hundreds of years, Asian natives used the mangosteen fruit to treat a variety of sicknesses and conditions, without any clue as to the nature of the active ingredients in their concoctions using the mangosteen fruit or why they worked. Today, because of the mangosteen xanthones research done worldwide, we can understand why the potions, preparations, and poultices used by
the natives of Asia were effective enough to endure through time. 31 Mangosteen Research Studies
