Abstract
Selection of conditions is performed for mechanochemical activation of Siberian larch wood and for aqueous extraction that provide the maximum yield of arabinogalactan (AG) and dihydroquercetin (DHQ). The possibility of processing an extracted wood of larch to produce microcrystalline cellulose (MCC) by the use of the organic solvent delignification process with acetic acid-water-hydrogen peroxide mixture in the presence of sulphate catalyst was shown. A diagram for comprehensive processing of larch wood to yield AG, DHQ, MCC, and low-molecular lignin is suggested.
