Although the extractives are a minor component of wood, they have an important influence on wood properties. In this work the content of extractives in 40 years old Aspen poplar (Populus tremula L.) wood was determined by ethanol-toluene and hot-water extraction. Spectroscopic characterization of these extracts was carried out by using ATR-FTIR spectroscopy. The FTIR spectrum of ethanol-toluene extract indicated the presence of fatty acids, esters and sterols, and the FTIR spectrum of hot-water extract indicated the presence of carbohydrate and phenolic substances.
