Trolox is Hoffman-LaRoche's trade name for 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid, a water-soluble derivative of vitamin E. It is an antioxidant, like vitamin E, and is used in biological or biochemical applications to reduce oxidative stress or damage.
Trolox equivalent antioxidant capacity (TEAC) is a measurement of antioxidant strength based on Trolox, measured in units called Trolox Equivalents (TE), e.g. micromolTE/100 g. Due to the difficulties in measuring individual antioxidant components of a complex mixture (such as blueberries or tomatoes), Trolox equivalency is used as a benchmark for the antioxidant capacity of such a mixture. Trolox equivalency is most often measured using the ABTS decolorization assay.[1] Other measures include oxygen radical absorbance capacity (ORAC) and ferric reducing ability of plasma (FRAP).
