The invention relates to a method for producing taxifolin, having the following steps: stacking wood particles in a percolator; extracting the wood particles in the percolator using ethanol in order to dissolve at least resins, oils, and taxifolin; conducting the ethanol extract out of the percolator; and purifying the ethanol extract in order to produce taxifolin using the following steps in the given sequence: producing a mixture of water and the ethanol extract; mixing the mixture at 70 °C to 99 °C such that the taxifolin dissolves in the water phase of the mixture; cooling the mixture to below 65°C in order to separate and conduct the resin phase and the oil phase from the water phase; adding taxifolin seed crystals to the water phase; controlling the temperature of the water phase to 0 °C to 30 °C in order to crystallize the taxifolin; and separating the crystallized taxifolin from the mother liquor. |
