The hemicelluloses of the wood of English oak

Abstract

Hemicellulose A was prepared from the sapwood and heartwood of English oak before and after various methods of drying (air, kiln, oven-dried). With increasing severe conditions of drying the hot water and NaOH extracts of wood increase in amount and the hemicellulose A decreases. The pentosan content of hemicellulose A also decreases as the treatments become more severe.
