About this study

Official title: Bioavailability and Anti-inflammatory Activities of Mangostins: a Pilot Study

Mangosteen is a tropical tree. The peel of mangosteen fruit is used in traditional medicine. The purpose of this study was to determine the bioavailability of the xanthones from mangosteen juice in adult human subjects.

Read the detailed description

Garcinia mangostana L. (mangosteen) is a tropical tree native to Southeast Asia. The pericarp of mangosteen fruit is used in traditional medicine to treat inflammation, infections, wounds, and diarrhea. The proposed health-promoting effects have been attributed to a family of polyphenols referred to as xanthones. Since its introduction into the United States, juices and products containing mangosteen fruit have become a top-selling botanical dietary supplement. This commercial success largely has been the result of aggressive marketing of health claims based on in vitro observations and anecdotal reports.

The purpose of this study was to determine the bioavailability of xanthones from mangosteen juice in adult human subjects. After an overnight fast of at least 10h, male and female subjects were admitted to the Ohio State University Clinical Research Center. Volunteers ingested 2 ounces of 100% mangosteen juice as part of a western-style breakfast. Pericarp particles accounted for 1% of the mass and 99% of total xanthone content in the juice. This dose provided 130 ± 2 mg total xanthones. Blood was collected prior to breakfast and 1,2,3,4,6,8 and 24h. Subjects were fed a mangosteen-free lunch and released from the unit after the 8h collection, refraining from mangosteen containing products until final collection of blood at 24h. Urine was collected for the 24 test period.

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy Volunteers, run by Mark Failla at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Sep 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Xanthones in urine (time frame: 0-24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01425047, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2011.
