Table I. Antioxidant activity of tetracycline, a-tocopherol, trolox, quercetin and resveratrol determined using the induction period method.

The values were determined based on the DSC data reported previously (23) using differential scanning calorimetry (DSC) monitoring of the polymerization of MMA (9.4 mol) initiated by thermal decomposition of AIBN (azobisisobutyronitrile) or BPO (benzoyl peroxide) under nearly anaerobic conditions at 70˚C. The procedure is described in the text. Conversion, 84.9-96.9%. *Induction period, **Propagation rate constant. The values are the means for two or three independent experiments. Standard errors were <15%.
