Antioxidants themselves are measured by their ORAC value: (Oxygen Radical Absorption Capacity). The ORAC analysis, developed by the National Institutes of Health in Baltimore provides a measure of the scavenging capacity of antioxidants against the peroxyl radical, which is one of the most common reactive oxygen species found in the body. Trolox, a water-soluble Vitamin E analog, is used as the calibration standard and the ORAC result is expressed as micromole Trolox equivalent (TE) per gram. The acceptable precision of the ORAC assay is 15% relative standard deviation. The USDA recommends an ORAC unit ingestion of between 5-6,000 units daily. The average human daily diet is considerably less.
Below you will find a number of interesting web sites (In vivo human study support data) supporting some of the findings in mangosteen research.
This article specifically examines the potential power of the natural xanthones in the mangosteen fruit.
This article quantifies the antioxidant effects of the various parts of the mangosteen fruit. Clearly, some parts have a greater capacity to scavenge free radicals, but, most importantly, positive results are concluded.
Whilst this article focuses on the potential cancer modulating effects of the mangosteen fruit, its potential to detoxify the body and ameliorate cytotoxic cells looks positive.
This study is important because it cites alpha-mangostin as increasing glutathione levels which is the body’s main antioxidant enzyme, therefore it demonstrates its powerful antioxidant effects.
Another positive study to evaluate the antioxidant activity specifically of gamma-mangosteen
This provides a comprehensive review of the many positive potential health benefits of mangosteen, specifically the xanthones, which provokes a good all-round discussion.
