The invention discloses a method for extracting grape anthocyanins, which comprises the following operation steps: (1) taking a grape raw material, adding an extractant and standing, wherein the extractant is prepared by mixing ethanol and furan, and the volume ratio of ethanol to furan being (1 to 2):(0.5 to 1.5); (2) placing the matter obtained in the step (1) by standing at subzero 8 DEG C to subzero 1 DEG C, taking out, heating to 40 DEG C, and then heating to 65 to 85 DEG C, and maintaining the temperature for extraction for 1 to 3 hours, so as to obtain the grape anthocyanins. By adoption of the method disclosed by the invention, the extractant can extract more anthocyanins contained in grapes, the method is simple and time-saving, and industrialized production is easy to realize.
