A Pyranine based Procedure for Evaluation of the Total Antioxidant Potential (TRAP) of Polyphenols: A Comparison with closely related Methodologies

A Pyranine based Procedure for Evaluation of the Total Antioxidant Potential (TRAP) of Polyphenols: A Comparison with closely related Methodologies

A novel procedure for the evaluation of total reactive antioxidant potentials (TRAP) is described. The method is based on the measurement of the bleaching of pyranine by peroxyl radicals. The addition of the antioxidants produces a clear induction time whose magnitude is directly related to the anti...
