摘要：The article illustrates about the synthesis of Mn(II)-Morin complex in methanol solvent. The characterization of the complex was carried out using UV-visible,IR,1H NMR spectroscopic techniques and thermal (i.e. TGA,DSC) techniques. The complex formation was deduced by UVvisible spectra showing the successive Mn-Morin complex formation occurring at 1:1 (metal/ligand) ratio stoichiometrically. The antioxidant capacity of the complex has also been evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging method. The work describes that flavonoids complexed with metal ions are more free radical scavengers than the free molecules..
