Rezumat

After modifi cation of enotannins, fl avonols monomer units could be obtained with polyfunctional properties. Moreover, polyphenols are known to generate H2O2 and other free radicals under alkaline conditions. Reactive oxygen species generation and catalytic infl uence of ferrous ions enhance the chemiluminescence light. Therefore, Oxidized Tannin/Tris-EDTA/Fe2 ions system have been used for screening luminescent properties of oxidized tannins.
