Disclosed is a method for separating and preparing delphinidin-3-O-(6″-O-p-coumaroyl) glucoside. By means of extraction, macroporous resin purification, extraction, preparative liquid chromatography and high-speed countercurrent chromatography and the like, a high-purity delphinidin-3-O-(6″-O-p-coumaroyl) glucoside monomer can be obtained from grapes by separation and purification. By means of this method, at least 80 mg of delphinidin-3-O-(6″-O-p-coumaroyl) glucoside can be obtained from 10 kg of grape skins, with the purity can be no less than 98%. The method has the advantages of simple operation, large handling capacity, good repeatability, etc., which provides a new idea for the development and utilization of grape resources.
