Abstract : This report extensively reviews the chemistry of extractives from wood and bark of hardwoods from the eastern United States. While such extractives are not used to a great extent commercially, they may influence properties of the wood and performance of wood products. For example, extractives can protect wood from decay, add color and odor to wood, accent grain pattern, and enhance strength properties. Extractives may also inhibit setting of concrete, glues, and finishes; cause problems in papermaking; contribute to corrosion of metals in contact with wood; present health hazards, and affect color stability of wood to light. Hardwoods in this review are grouped and discussed alphabetically by their respective botanical families. Grouping botanically makes it possible to draw chemotaxonomic inferences related to genera. Literature searches cover 22 families and 174 species; species by family are listed at the beginning of each discussion section. (Author)
