Development and validation of an improved oxygen radical
absorbance capacity assay using fluorescein as the fluorescent probe.
Both hydrophilic and lipophilic oxygen radical
absorbance capacity (ORAC) assays were carried out at Brunswick Laboratory (Wareham, MA) based on the modified [ORAC.
Of these factors, oxygen radicals
and crosslinking of proteins have become focal points of scientific exploration.
Automated assay of oxygen radical
absorbance capacity with the COBAS FARA II.
Both acetaldehyde and oxygen radicals
can interact with proteins and other complex molecules in the cell, forming hybrid compounds called adducts.
The investigators calculated estimates of total antioxidant capacity from a database that measures the oxygen radical
absorption capacity (ORAC) of the most common foods in the United States (no equivalent database of Swedish foods exists).
Formulators will now be able to add the nutrient and antioxidant-rich attributes of some of the highest-ranking Oxygen Radical
Absorption Capacity (ORAC) fruits such as acai, pomegranate, cranberry, blueberry and black currant to their formulations in a completely new and innovative way, accoording to the company.
The company says the Montgomery tart cherries in the juice have a higher oxygen radical
absorption capacity than blueberries or green tea and contain anthocyanins, which have been shown to improve joint health and ease arthritis pain.
Known methods include the active oxygen method (AOM) and its automated versions (Rancimat and SAFFEST) for lipophilic phases, and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) or oxygen radical
absorption capacity (ORAC) for aqueous environments.
Laboratory research has demonstrated that Ceplene reduces oxygen radical
formation and release of phagocytes by inhibiting NADPH oxidase, thus protecting IL-2-activated NK-cells and T-cells from oxygen radical
-induced inhibition and apoptosis.
When these herbs were incubated with inflamed biopsy specimens, they decreased oxygen radical
