Abstract

Wood extractives are organic components that even not being part of the cell wall, have an important impact on wood properties and its utilization. The study was carried on extractives content of white oak (Quercus petraea Liebl). Eighteen sawdust samples were taken from cuts in six different heights of three trees. The extraction is done with Soxhlet 250 ml capacity, for about 6 h. The content of extractives decreased from the base to the top of the tree and their content in wood was 4.7%. This result is near to those recommended in literature for Quercus sp.

Key words: Extractives, extraction solvent, Soxhlet, evaporator, white oak.
