THE STUDY OF ANTIOXIDANT ACTIVITY OF ROSA CANINA FRUCTUS AND ARONIA MELANOCARPA FRUCTUS LIQUID EXTRACTS
. In the study of antioxidant activity of Rosa canina fructus, Aronia melanocarpa fructus and their composition liquid extracts with electron paramagnetic resonance method it was established that 50% of extract from Rosa canina fructus had the most expressed antioxidant properties. The extracts were obtained with dynamic fractional maceration. It should be noted that 50% summing extract had also strong antioxidant properties. Ethanol of 50% concentration provided higher concentration of natural antioxidants in the extract, i.e. 50% ethanol is a more optimal extracting agent than 70% ethanol.
