have the capacity to complex a wide variety of metallic ions which could affect their bioactivity. In order to assay the complexant capacity of flavonoids, the metallic ion Cu(II) was selected. The formation of two flavonoid–Cu(II) complexes in ethanolic solutions were studied, and both complexes presented 2:1 L–M stoichiometries. The apparent formation constants for quercetin–Cu(II) are higher than those
