Synthesis, Characterization and Antioxidative Activity of Metal Complexes with Rhein 

 -  Acta chimica sinica, 69(8), p.925-930, 2011 .
<br/><br/> Three metal complexes with rhein ML 2 2H O [L=rhein (1-OH group deprotonated)]; M= Cu(II), Fe(II), Mn(II)] have been synthesized and characterized by elemental analysis, molar conductance, IR, 1 2 H NMR, TG-DSC and UV-Vis spectroscopic techniques and by fluorescence analysis. The scavenging effect on the superoxide radical (O 2 - ), hydroxyl radical (OH), DPPH were also compared. The metal complexes are stronger than rhein for antioxidant activity.
