FIELD: chemistry.
SUBSTANCE: invention relates to a method for extracting and isolating constituents of cellulosic material, comprising: (a) contacting the cellulosic material with a supercritical fluid under conditions to provide an extract; (b) removing insoluble material from the extract; and (c) fractionating the extract by distillation under depressed pressure to provide one or more isolated constituents.
EFFECT: solvent can be removed from the extract without the need for an additional processing step.
