We discussed and summarized the latest data from global literature on action of polyphenolic antioxidants their metal complexes. The review also includes a summary outcomes theoretical computations our many years experimental experience. employed various methods, including spectroscopy (FT-IR, FT-Raman, NMR, UV/Vis), X-ray diffraction, thermal analysis, quantum calculations, biological assays (DPPH, ABTS, FRAP, cytotoxicity, genotoxicity tests). According to research, number position hydroxyl groups in aromatic rings, as well delocalization electron charge conjugated double bonds, have major impact antioxidant effectiveness studied compounds. Another important factor is complexation, whereby high ionic potential metals (e.g., Fe(III), Cr(III), Cu(II)) enhance properties by stabilizing charge, while low Ag(I), Hg(II), Pb(II)) reduce efficacy disrupting distribution. However, we observed no simple correlation between capacity. This paper gives insights that will aid identifying new, effective antioxidants, which are vital for nutrition prevention neurodegenerative illnesses.
