Iron Chelating Activity of Gossypitrin Isolated from the Petals of Talipariti elatum Sw. (Fryxell) Malvaceae

Abstract

A Fe(III)-gossypitrin complex was prepared with a metal to ligand molar ratio of 1:1; 2:1 and 3:2 by mixing stoichiometric amounts of gossypitrin and FeCl₃. The isolated complex was characterized by visual observation, UV/Vis, IR and ESI-MS spectroscopy. In this study, we selected the major flavonoid glycoside present in the petals of the flowers of Talipariti elatum Sw. (Fryxell) Malvaceae that grows in Cuba, gossypitrin, to characterize the chelating activity of it chemical compound with FeCl₃, to find alternative sources with lower side effects in asthmatic patients. A high chelating activity can be observed as a good source of new agents for asthmatic patients.
