摘要：
The extractive substances from spruce bark (Picea abies) were studied by accelerated solvent extraction (ASE). ASE was carried out by ethanol and the temperature was 80, 120 and 160 degrees C. Structural characterizations of the extractives were carried out by using FTIR and GC/MS analysis. It was found that with increasing temperature increased extractivity of substances in all evaluated samples. The FTIR analysis was used to identify the extracted substances. By GC/MS the main groups identified included fatty acids, sterols, waxes, sterols and steroids.
