The invention provides a preferable method for extracting refined yellow pigment from red flowers, which adopts the technology integration of extracting and refining, resin adsorption, nano filtration separation, outer circulating vacuum reduced pressure concentration and spray drying. The method is as follows: performing particles removing, ashing and sterilization on primary filtrate by a filter; adsorbing resin with large aperture by alcohol, wherein the upper prop adsorbing flow is 1-4BV / h, the adsorbing time is 1.5-2.0 hours, the eluting flow is 2-6BV / h, and the eluting time is 2.5-3.0 hours; collecting eluent, wherein the PH values of upper prop liquid medicine and cleanout fluid are 2-5; depredating macromolecules by a microfiltration membrane, wherein the control pressure is 0.1-0.2MPa, the temperature is 5DEG C higher than the room temperature or 5 DEG C lower than the room temperature; thickening and dewatering by a nanofiltration membrane, wherein the control pressure is 1-4MPa, the temperature is 20-50 DEG C, and the concentration multiplying power is 5-10 times; recycling the alcohol; and drying a material the solid content of which is 40%-60% to obtain the product, wherein the feed temperature is 60-80 DEG C, the entering air temperature is 160-190 DEG C. By implementing the preferable method, the extraction ratio of the yellow pigment reaches more than 80%, and the color value also reaches more than 150.
