Report on ORACFL Values of Artichoke/Sarsaparilla Extract, Brunswick Laboratories 2002
Oxygen Radical Absorbance Capacity (ORAC) measures the ability of the sample being analyzed to protect against attack by free radicals, or to act as an antioxidant. Several methods have recently been developed to measure the total antioxidant capacity of biological samples, but the ORAC method is quite unique. It measures the degree to which a sample inhibits the action of an oxidizing agent and how long the inhibiting effect lasts. It then integrates the two measurements into a single one. This provides an accurate and reproducible measurement for different types of antioxidants having different strengths.
The ORAC procedure provides a measure of total antioxidant capacity and will measure the common nutrient antioxidants such as vitamin C, vitamin E, β-carotene, etc., plus a number of other naturally occurring phytochemicals, such as the flavonoids and phenolic acids. The standard of comparison in this procedure is Trolox (a water-soluble analog of vitamin E), which is defined as Trolox Equivalents (TE).
The ORACFL analysis, which utilizes Fluorescein as the fluorescent probe, provides a measure of the scavenging capacity of antioxidants against the peroxyl radical, which is one of the most common reactive oxygen species (ROS) found in the body.

There is much being studied and written in the scientific world about antioxidants, phytochemicals, and nutraceuticals, with a tremendous amount of research underway to determine the role that specific antioxidants play in protecting the body from harmful free radicals. Free radicals are atoms or groups of atoms that can cause damage to cells, impair the immune system, lead to infections and various degenerative diseases such as heart disease and cancer. These free radicals can be caused by exposure to radiation, toxic chemical exposure, and various metabolic processes. Free radicals are kept in check by the action of antioxidants. Antioxidants neutralize free radicals.
Although antioxidants can be obtained from food sources, such as fresh fruits and vegetables, it is difficult to obtain all that we need in our daily diets. It is also known that it is best to take various types of antioxidants, not just one, since they work synergistically to minimize free radical damage.
