A method for preparing plant extracts with antiradical activity in a subcritical water medium is proposed. The method makes it possible to extract from plant material in subcritical water up to 38% of substances of various chemical natures, such as phenolic compounds, without using toxic organic solvents. The method is tested by the example of preparing extracts from blood-red hawthorn (Crataegus sanquinea Pall.), heart-shaped linden (Tilia cordata Mill.), sand immortelle (Helichrysum arenarium L.), chamomile (Matricaria recutita L.) and touch-and-heal (Hypericum perforatum L.). It is shown that the aqueous and ethanol fractions of plant extracts have comparable antiradical activity, as assessed using their reaction with diphenylpicrylhydrazyl radical.
