Chemical composition of lipophilic extractives from Eucalyptus globulus Labill. wood

The composition of lipophilic extractives in the chloroform soluble fractio n of the acetone extract from Eucalyptus globulus wood has been examined. T he lipid extract was fractionated by solid-phase extraction on aminopropyl- phase cartridges into four different fractions of increasing polarity. The total lipid extract and the resulting fractions were analyzed by gas chroma tography and gas chromatography-mass spectrometry, using high temperature c apillary columns. The main compounds identified included sterols, sterol es ters, fatty acids, steroid ketones, hydrocarbons and triglycerides. Minor c ompounds such as fatty alcohols, mono- and diglycerides, waxes and tocopher ols were also identified among the lipids from E, globulus wood.
