Method for extracting and separating xanthohumol and flavone compounds

The invention relates to a method for extracting and separating xanthohumol and flavone compounds. The method comprises the following steps of: leaching hops and a supercritical CO2 extraction residue thereof with an alcohol solution to ensure that flavone compounds, particularly xanthohumol, are sufficiently dissolved out; filtering to obtain a filter liquor after leaching, and decompressing anddistilling the filter liquor to obtain a concentrated liquor; centrifuging the concentrated liquor, taking an obtained supernate, and filtering by using a 0.45muL of organic film; removing partial impurities, and eluting with an eluant to elute the flavone compounds from macroporous adsorption resin; collecting effluent liquid and concentrating; and freezing and drying to obtain yellow powder. In the invention, the hops, the supercritical CO2 extraction residue, and the like are used as raw materials, particularly, a waste material which is the supercritical CO2 hop extract extraction residuein a hop product processing process is used as the raw material, thus the xanthohumol which has the main efficacy and is difficult to separate is independently extracted, and other flavone compounds rich in the hop waste material are also extracted; and the invention also provides a development approach for hops which cannot be used for beer brewing, thereby improving the resource utilization ratio and the added value of the hops and having important significance to prolonging the hop industrial chain.
