The spectrophotometric technique for total antioxidant activity (TAA)(1,2) measures the relative abilities of antioxidants to scavenge the 2,2'-azino-bis(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) radical cation (ABTS(•+)) in comparison with the antioxidant potency of standard amounts of Trolox, the water-soluble vitamin E analogue. This method is based… CONTINUE READING
