Abstract The term extractives is mostly used to denote the hydrophobic (lipophilic) components both in wood and in pulp and paper samples that are extractable with neutral solvents (Hillis 1962; Ekman 1979; Saranpää and Nyberg 1987; Fengel and Wegener 1989; Rowe 1989; Kai 1991; Sjöström 1993). These water-insoluble, lipophilic extractives are also called wood resin. However, although some of the phenolic extractives, mainly occurring in heartwood, can be dissolved in organic solvents, they are not usually considered true wood resin components. Sometimes the term extractives is used more broadly, to also include water-soluble substances, thus covering essentially all wood components other than cellulose, hemicelluloses, and lignin.
