摘要

Ml s-1, 10 times that of a-tocopherol or any model compound, and is the most active phenolic antioxidant known. Class 111, hydroquinones including 2, 3, 64rimethylhydroquinone and the a-, 8-, and y-tocopherylhydroquinones, are 2 to 4 times less active as antioxidants than a-tocopherol, and class IV, the ubiquinones, are 8-10 times less active than a-tocopherol. The stoichiometric factors, n, for peroxyl radical trapping are ...
