A METHOD FOR ISOLATING DIETARY FIBER ARABINOGALACTAN AND ARABINOGALACTAN IN COMBINATION WITH FLAVONOID DIHYDROQUERCETIN (TAXIFOLIN) FROM CONIFER WOOD SPECIES OR HARDWOOD INCLUDING BUTT LOGS AND BARK
A method for isolating arabinogalactan and arabinogalactan with flavonoid dihydroquercetin (taxifolin) from wood, including butt logs and bark. The method includes extracting an extract from a combination of a polar solvent with wood particles and recovering the extract. The wood particles include at least one of i) a particle-reduced chip fraction obtained by subdividing the butt logs into chips, and ii) a dry cork fraction of the bark or a powdered bark obtained as a residue in finishing of mechanical wood products. The wood is a coniferous hardwood or a coniferous wood selected from the group consisting of a wood of a Larix genus, a spruce wood of a genus Picea, a fir wood of a genus Abies, a pine wood of a genus Pinus, or a wood of a Pseudotsuga genus.
