Abstract: 

The paper presents the results of a study of antioxidant properties of plant extracts. The aim of the work was to study the effect of extraction conditions on the extraction of biologically active substances (BAS). The objects of investigation were water-alcohol and oil extracts of medicinal plants. Removing a complex of biologically active substances was performed by repeated two-phase extraction and ultrasonic extraction. The relative antioxidant activity of the extract was indicated as volume of extracts in milliliters, consumed for the titration of 1 ml of 0.05 N solution of potassium permanganate. Finally, conclusions are drawn on the impact of the extraction conditions on the content of biologically active substances with antioxidant properties in the resulting extracts.

Keywords: 

biologically active substances, two-phase extraction, ultrasound, antioxidants, antioxidant properties.
