Abstract

For the first time a dependence of the technical lignin extractive substances yields on duration of steam-explosion treatments is investigated. Chemical composition of the extractive substances is analyzed by means of gas chromatography-mass spectrometry method with the use of internal standards.In order to obtain reliable data the extractive substances are examined by gas chromatography-mass spectrometry using two methods of derivatization: silylation and methylation by diazomethane. In all the analyzed samples high concentrationsof dehydroabietic acid and other resin acids have been detected. Fatty acids С16-С24 and sterol components (campesterol, sitosterol and sitostanol) have been revealed as well.
