The Reactions of Extracts from Maple and Oak Leaves with Iron and Zinc Compounds1

F. L. Himes, R. Tejeira and M. H. B. Hayes2

ABSTRACT

A water extract of oak leaves solubilized more iron from freshly precipitated ferric hydroxide at three pH's than the extract of maple leaves. The influence of the hydrogen-saturated extracts on the equilibrium of iron and zinc between solution and sodium-saturated Dowex resin were studied. More iron was solubilized when the extract was present than when absent, and the two extracts were similar. The influence of the extracts on equilibrium with zinc was very small. With paper strip electrophoresis, the iron moved with the extract toward the anode and the zinc moved toward the cathode. The higher molecular weight substances precipitated when the pH of the solution was raised to 5.2. The infrared spectra of the hydrogen-saturated and iron-saturated extracts indicate that carboxyl groups are involved in the reaction of iron with the organic constituents of the extract. Since zinc did not react with the constituents in the extract but iron did react, phenolic groups were probably involved in the reactions with iron.
