The antioxidative activities of nineteen compounds of seven series of alkylidene-and benzylidenebisphenols were evaluated by means of an oxygen-absorption method at 60° C for tetralin. The electrochemical oxidation potentials determined using linear-sweep voltammetry and the 13 C NMR chemical shifts (δ) of these compounds were obtained. These data were associated with the antioxidative activities. In particular, the activities ...
