Synthesis, Characterization and Antioxidant Activity of Fe(III)-Valex Complex

Abstract

Iron (III) complex with a mixture of hydrolysable tannins from the fruits of Valonia Oak (Quercus ithaburensis sp. macrolepsis) known as Valex was synthesized and characterized using various techniques . Stoichiometry of the complex was determined to be M 2 L at pH 4.4 with the stability constant (K) of 1.5 ´ 10 8 L 2 mol -2 . The antioxidant, antimicrobial and antifungal activity of the Fe(III)-Valex complex was studied. The Fe(III)-Valex complex was found to have antioxidant activity but did not show any antimicrobial and antifungal activity against the tested microorganisms.
