摘要：
1. A method for isolating a flavonoid of the timber, including the butt portion of the wood, bark and roots, said method comprising the following steps: a) extraction of the extract from the polar solvent mixture with the wood particles comprising at least one of nizheukazannyhi) fraction is crushed to a particle size of chips obtained by crushing chips on said butt portions and roots, and ii) a secondary fraction dry bark or bark crushed obtained as waste in the production of mechanical wood products and b) separating said extract resulting from said extraction steps, using the wood of conifers selected from the group consisting of larch (genus Larix), spruce (genus Picea), fir (genus Abies), pine (genus Pinus ), wood genus Pseudotsuga, and wherein the basic substance is emitted from all of the above flavonoid species is obtained and the wood is hardwood porod.2. The method of claim. 1, characterized in that the polar solvent is a polar agent, or a mixture of two or more polar agentov.3. A method according to claim. 2, characterized in that the two polar agent in said mixture comprise from 20% to 40% ethanol and 80% to 60% water (v / v) .4. The method of claim. 1, characterized in that said extraction step is performed in a vacuum system in which the energy is used for heating said mixture of said polar solvent in contact with said wood particles to remove said flavonoid dihydroquercetin (taxifolin) of said wood particles .5. A method according to claim. 3, characterized in that said extraction step is carried out in a vacuum system in which the energy is used1.
