A phytochemical comparison of essential oil  and supercritical fluid CO2- extract (SCF-NI2-extract),  and analysis of residues obtained from the leaves of eucalyptus (Eucalyptus viminalis  Labill.) are performed. Compositions of essential oil and SCF-CO2-extract are similar qualitatively, but significantly differ in relative  amounts of their main components. SCF-CO2-extract  contains substantial amounts of sesquiterpens in addition to essential oil. The  residue remaining after the separation of lypophylic fraction is
found to be a source of phenoloaldehyds,  which can serve as constituents of pharmaceuticals (Eucaliminum and  Chlorophylli ptum). The properties of residues remaining after the SCF-CO2-extraction are more technically advantageous.
