Does the Combination of Resveratrol with Al (III) and Zn (II) Improve its Antioxidant Activity?

This communication describes the in situ combination of Al(III) and Zn(II) with resveratrol, and evaluation of the antioxidant power of the novel species via DPPH • assay. The formation of the complexes in aqueous medium was verified by Job's method, using fluorescence spectroscopy. The metal / ligand stoichiometry for the Zn(II) / resveratrol complex was found to be 1:2 and, for the Al(III) / resveratrol complex two preferential species were...
