The invention discloses a production method of a tartary buckwheat quercetin extract, which comprises the following steps: carrying out superfine grinding on tartary buckwheat bran to enable the material fineness to reach 120-300 meshes; extruding and granulating the crushed tartary buckwheat bran to prepare material granules of 1-3mm; the material particles are heated and tempered in a microwave mode, and the temperature of the materials reaches 70-100 DEG C; performing high-concentration ethanol extraction on the cured and tempered material particles under an ultrasonic processor with the power of 400W; carrying out solid-liquid separation on the slag-liquid mixture by using a filter, and separating the leaching liquid from the leaching particles; heating the filtered leach liquor to 80-90 DEG C, and volatilizing ethanol; removing grease from the leach liquor from which the ethanol is volatilized by using a filter; and concentrating the oil-removed extract liquid at 95 DEG C by using a vacuum concentrator,
