Abstract:

Electrochemical assay has been employed recently to study the activity of antioxidants; however, there is controversy as to whether reducing power fully characterizes the antioxidant activity. This study provides some essential further evidence on this point based on the reported data and mechanisms underlying the antioxidant functions as well as the anodic oxidation of phenolic antioxidants, indicating that further consideration and investigation should be made before reducing power is used as the absolute measure of antioxidant activity.
