 Experimental detection and determination of the concentration of several groups of biologically active substances in aqueous-ethanolic extracts of avocado seeds (Persea americana Mill.) reliably confirmed the presence of phenols (up to 1.19 mg/ml), flavonoids, and amino acids. Extracts of dried avocado seeds, prepared using 40% ethanol as an extractant, demonstrated the highest antioxidant activity. Comparative determination of the level of antioxidant effect of the analyzed extracts established the effectiveness of reducing lipid peroxidation to 55.7 % and protein oxidative modification to 26.9 % relative to the control sample.
