Synthesis and Characterization of Quercetin and Europium Complex Modified by Nano Fe₃O₄

Abstract

Extracted rutin from the bud of Sophora japonica, then prepared quercetin by hydrolyzing indirectly the solution of rutin crystal with sulfuric acid, the quercetin and Europium complex can be prepared by quercetin and Europium oxide, which served as raw materials reacted with each other under certain conditions. Then joined in the Fe₃O₄ nanometer ethanol in 30°C and reacted 24 h paramagnetic quercetin-Eu metal complexes can be obtained. The complex of quercetin and Europium modified by Fe₃O₄ is studied by UV, IR spectrophotometry and magnetometer. It may be formed quercetin-Europium complex in A and C ring of quercetin, the quercetin hydroxyl and nano Fe₃O₄ is combined with the possibility of hydrogen, the complex of quercetin and Europium modified by nano Fe₃O₄ is measured by magnetometer, the complex have magnetic strength.
