Key words: extraction, subcritical water, eucalyptus viminalis, 1,8-cineole

Extraction of biologically active substances from the leaves of eucalyptus viminalis is carried out by subcritical water in the temperature range 120—200 °C and a pressure of 5 MPa, as well as solutions of ethanol in water of different concentrations at 200 °C and 5 MPa. The extracts are analyzed using gas chromatography-mass spectrometry. Identification of the detected volatile organic compounds is realized. The content of α-pinene, β-pinene, α-phellandrene, p-cymene, 1,8-cineole in obtained extracts is determined.
