Abstract:
Extractive substances from spruce bark (Picea abies) were studied after accelerated solvent extraction (ASE). ASE was carried out by using ethanol and the temperatures were 100, 130, 150 and 180°C. The composition of the bark extractives were analysed by gas chromatography/mass spectroscopy (GC/MS). The extractives consisted mainly of fatty acid and monoterpene fractions, especially methyl oleate; methyl isopimarate; 7-oxodehydroabietic acid, methyl ester; methyl lignocerateand methyl behenate and methyl dehydroabietate.
