Xanthones are a class of polyphenolic compounds that commonly occur in plants and have been shown to have extensive biological and pharmacological activities. The pharmacological properties as it relates to the cardiovascular system and potential anti-tumor benefits have attracted great interest. Mangosteen is a fruit grown in Thailand and Myanmar whose rind (the pericarp) have some medicinal properties, probably due the high amount of xanthones. There are other plants besides mangosteen that also have these substances.
Benefit and research studies,
Xanthones and derivatives have been shown to have beneficial effects on some cardiovascular diseases, including ischemic heart disease, atherosclerosis, hypertension and thrombosis. The protective effects in the cardiovascular system may be due to their antioxidant, antiinflammatory, platelet aggregation inhibitory, antithrombotic and/or vasorelaxant activities. In particular, the antagonism of endogenous nitric oxide synthase inhibitors by xanthones may represent the basis for improved endothelial function and for reduction of events associated with atherosclerosis. They may also have anti-tumor activity thus potentially having an influence in the prevention or treatment of certain cancers.
As of 2015, I am not aware of human studies with xanthones derived from mangosteen.

What's in mangosteen fruit
Several compounds in mangosteen appear to be active, particularly xanthones. Some of these include mangostin, mangostenol, mangostenone A, mangostenone B, trapezifolixanthone, tovophyllin B, alpha- and beta-mangostins, garcinone B, mangostinone, mangostanol, mangosharin, and the flavonoid epicatechin.
J Nutr. 2012. Xanthones in mangosteen juice are absorbed and partially conjugated by healthy adults. Results show that xanthones in mangosteen juice are absorbed when ingested along with a high-fat meal.
Bioavailability and antioxidant effects of a xanthone-rich Mangosteen product in humans.
J Agric Food Chem. 2009. Brunswick Laboratories, Norton, Massachusetts, USA.
This study investigated the absorption and antioxidant effects of a xanthone-rich mangosteen liquid in healthy human volunteers after the acute consumption of 59 mL of the supplement. The liquid contained mangosteen, aloe vera, green tea, and multivitamins. Results indicated that alpha-mangostin and vitamins B(2) and B(5) were bioavailableh. The antioxidant capacity measured with the oxygen radical absorbance capacity (ORAC) assay was increased with a maximum effect of 18% after 2 h, and the increased antioxidant level lasted at least 4 h. Overall, this study demonstrated the bioavailability of antioxidants from a xanthone-rich mangosteen product and its in vivo antioxidant effects.
Aromatase inhibition and
potential breast cancer inhibition
Xanthones from the botanical dietary supplement Garcinia mangostana with aromatase inhibitory activity.
J Nat Prod. 2008. Department of Medicinal Chemistry and Pharmacognosy, Program for Collaborative Research in the Pharmaceutical Sciences, College of Pharmacy, University of Illinois at Chicago, Chicago, Illinois, USA.
Twelve xanthone constituents of the botanical dietary supplement mangosteen (the pericarp of Garcinia mangostana) were screened using a noncellular, enzyme-based microsomal aromatase inhibition assay. Of these compounds, garcinone D), garcinone E, alpha-mangostin, and gamma-mangostin exhibited dose-dependent inhibitory activity. In a follow-up cell-based assay using SK-BR-3 breast cancer cells that express high levels of aromatase, the most potent of these four xanthones was gamma-mangostin. Because xanthones may be consumed in substantial amounts from commercially available mangosteen products, the consequences of frequent intake of mangosteen botanical dietary supplements require further investigation to determine their possible role in breast cancer chemoprevention.
The natural xanthone alpha-mangostin reduces oxidative damage in rat brain tissue.
Nutr Neurosci. 2009. Instituto Nacional de Neurología y Neurocirugía Manuel Velasco Suárez, Insurgentes Sur México DF, Mexico.
The antiperoxidative properties of alpha-mangostin, a xanthone isolated from mangosteen fruit, were tested for the first time in nerve tissue exposed to different toxic insults. Two reliable biological preparations (rat brain homogenates and synaptosomal P2 fractions) were exposed to the toxic actions of a free radical generator (ferrous sulfate), an excitotoxic agent (quinolinate), and a mitochondrial toxin (3-nitropropionate). alpha-Mangostin decreased the lipoperoxidative action of FeSO(4) in both preparations in a concentration-dependent manner, and completely abolished the peroxidative effects of quinolinate, 3-nitropropionate and FeSO(4) + quinolinate at all concentrations tested. Interestingly, when tested alone in brain homogenates, alpha-mangostin significantly decreased the lipoperoxidation even below basal levels. alpha-mangostin exerts a robust antiperoxidative effect in brain tissue preparations probably through its properties as a free radical scavenger. In light of these findings, this antioxidant should be tested in other neurotoxic models involving oxidative stress.
Xanthones can cause apoptosis which could be beneficial in cancer.
H Pylori infection
Arch Pharm Res. 2013. Anti-Helicobacter pylori xanthones of Garcinia fusca. A new geranylated xanthone derivative, fuscaxanthone I (1), along with nine xanthones (2-9 and 11), a biphenyl (10) and three biflavonoids (12-14) were isolated from the roots of Garcinia fusca Pierre. Compounds 8, 10 and 11-14 were reported from this plant species for the first time. Their structures were elucidated by spectroscopic analyses, including 1D- and 2D-NMR and MS. The isolated compounds were evaluated for antibacterial activity against Helicobacter pylori. Cowaxanthone (5) and fukugiside (14) exhibited stronger inhibitory activity against H. pylori DMST reference strain at MICs 4.6 and 10.8 μM, respectively, than that of the control metronidazole. Isojacareubin (8) displayed the most potent activity against H. pylori HP40 clinical isolate with MIC 23.9 μM, which was approximately two times greater than that of the standard drug amoxicillin.

J Nat Prod. 1997.
The antifungal activity of several xanthones isolated from the fruit hulls of mangosteen and some derivatives of mangostin against three phytopathogenic fungi, Fusarium oxysporum vasinfectum, Alternaria tenuis, and Dreschlera oryzae, has been evaluated. These natural compounds showed good inhibitory activity against the three fungi.
Antimycobacterial activity of prenylated xanthones from the fruits of mangosteen.
Chem Pharm Bull. 2003.
Prenylated xanthones, isolated from the fruit hulls and the edible arils and seeds of mangosteen, were tested for their antituberculosis potential. Alpha- and beta-mangostins and garcinone B exhibited strong inhibitory effect against Mycobacterium tuberculosis.
J Med Assoc Thai. 2014. Xanthones from mangosteen (Garcinia mangostana): multi-targeting pharmacological properties. This review focuses on mangosteen pericarp extracts, xanthones and derivatives for the future laboratory experiment and development in pharmacological aspects. All relevant literature databases were searched up to 2 March 2014. The search terms included mangosteen, xanthone, mangostin, and gatanin in all of the human, animal, in vitro and in vivo studies. Anti-intflammation, antioxidant, antibacterial, anticancer and antiulcer properties of each substance were the key parameters. Xanthones are a group of oxygen-containing heterocyclic compounds including alpha-mangostin, gamma-mangostin, mangosteen extract, xanthone derivatives and synthetic xanthones, which provide remarkable and diverse pharmacological effects such as anticancer, antioxidant, anti-inflammatory and antimicrobial activities. These xanthone compounds may play a major role in therapeutic treatment ofthe diseases but precise mechanisms ofaction are still unclear and needfurther investigation.

Xanthones health benefit and side effects questions
Q. I am looking to find out some information in regard to 500mg mangosteen Capsules. In comparison to the Mangoxan juice or Juice Blend Garcinia Mangostan - what is the quantity of xanthones? Since they fight arthritis inflammation and would like to get the most amount for the money. Is 1000mg a day of xanthone in the mangosteen capsules the most effective amount to use for my purposes based on any studies? Or should I take perhaps more per day.
A. You may need to contact Mangoxan juice or Mangosteen Juice Blend Garcinia Mangostan companies to find out about their xanthone amounts in their juices. Fruit juices also have a combination of other fruits so the comparison becomes murky. Keep in mind that just going for the highest xanthones may be simplistic. Long term side effects of xanthones are not known.
Are Xanthones found in any
other fruits? If so, it would then substantiate Dr. Andrew Weil's claim
that Xango Mangosteen fruit juice is 'just an expensive fruit juice, you'd
be just as well off squeezing your own fruit juice from other fresh
Xanthones are found in other fruits but their concentrations are minimal to the amount found in mangosteen. Each fruit has its unique sets of beneficial compounds and hence it is a good idea to have a variety in one's diet or to alternate the use of various fruit extract supplements.
I would like to know if it is okay to use mangosteen which has
xanthones and so does St. John's Wort together with Zoloft and Xanax? I
know you can't use St. John's wort with these meds. and it contains
xanthones in it.
As far as we know, St. John's wort does not have a large amount of xanthones. Mangosteen is a safe supplement and one capsule a day should not interfere with medicines, but we have no studies to prove this viewpoint and your doctor would need to make the final decision.
We are currently at Thammasat University. We are developing a
business plan for a product that has xanthone as a core ingredient. The
role of xanthone has already been proven to kill the airborne TB bacteria
and product development is underway to create a bacteria eliminating
filter that can be used in medical masks etc. I wanted to ask you if you
had done any research on the killing properties of xanthone on bacteria?
Due to our limited budget we are unable to conduct this research
I am not familiar with their use in the treatment or prevention of tuberculosis.
I've been doing a research project wondering if xanthone has FDA
approval to be used on cosmetics, medicines and skin creams?
I have not looked into the cosmetic uses and FDA regulatory matters.
