Antioxidant properties of humic acids from brown coal

Abstract

It was demonstrated by a gas-volumetric method that humic acids from brown coal exhibit pronounced antioxidant properties, being the effective inhibitors of the model reactions of initiated radicalchain oxidation of hydrocarbons (cumene and ethylbenzene). This makes it possible to recommend humic acids for use as effective antioxidants for technical purposes and as promising biologically active natural antioxidants for the development of new classes of pharmaceuticals for medicine.
