Comment on the paper: "Spectroscopic and computational study of the major oxidation products formed during the reaction of two quercetin conformers with a free radical".
The title paper reports a study on the structural elucidation by spectroscopic and computational methods of the products obtained from the reaction of two conformers of quercetin with the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH(•)). Many points of criticism, concerning both theoretical principles and experimental data, are highlighted in the present communication.
