FIELD: chemistry.SUBSTANCE: present invention refers to developing brewing products. According to the invention, a method for preparing an extract of polyphenols as a result of brewage involves the stages: contacting partially purified beer with resin, which adsorbs polyphenols； desorbing polyphenols adsorbed on the resin contacting with partially purified beer； adsorbing polyphenols on the second resin different from the first one； the above second resin is hydrophobic and non-ionic； and desorbing polyphenols adsorbed on the second resin with using an organic solvent； implementing the method is ethylacetate-free. The invention also refers to the method for preparing the extract of polyphenols as a result of brewage that involves the following stages: contacting partially purified beer with hydrophobic and non-ionic resin, which adsorbs polyphenols； and desorbing polyphenols adsorbed on the resin used at the previous stage of contacting with using the organic solvent； a desorption product contains at least 0.85 g of polyphenols per one gram of a dry matter. The invention also refers to the extract of polyphenols prepared by the above method and containing catechin, epicatechin, thyrozol and ferulic acid. The invention also refers to a cosmetic product, a functional food product, a food additive, which contain the above extract of polyphenols in an effective amount. Also the invention provides using the above cosmetic product for skin moistening and/or ageing prevention or delay, using the extract of polyphenols for producing an antioxidant composition.EFFECT: invention provides preparing the extract of ethylacetate-free and high-purity polyphenols.19 cl, 23 dwg, 22 tbl, 6 exНастоящее изобретение относится к области разработки продуктов пивоваренной промышленности.
