The invention relates to a process for the manufacture of taxifolin, comprising the following steps: stacking the wood particles in a percolator, extracting the wood particles in the percolator using ethanol to dissolve at least resins, oils, and taxifolin, discharging the ethanolic extract from the percolator, and purifying the ethanolic extract for the manufacture of taxifolin with the following steps in the specified order: preparing a mixture of water and the ethanolic extract, mixing the mixture at between 70° C. and 99° C. so that taxifolin in the aqueous phase of the mixture goes into the solution, cooling the mixture to below 65° C. for separating and removing the resin phase and the oil phase from the water phase, adding taxifolin seed crystals to the water phase, temperature controlling the water phase at between 0° C. and 30° C. for the crystallization of taxifolin, and separating the crystallized taxifolin from the mother liquor.
