FIELD: chemistry.
SUBSTANCE: invention relates to a method of extracting betaine from a solution obtained from sugar beet. The method for chromatographic extraction of betaine from a solution obtained from sugar beet, which contains betaine, polyols and carboxylic acids, involves changing the pH of the solution to a certain value, chromatographic separation of the obtained solution on a weakly acidic cation-exchange resin in H+ form, elution of betaine after polyols and carboxylic acids, and collection of fractions rich in betaine; use of a weakly acidic cation-exchange resin in H+ form for chromatographic extraction of betaine from a solution obtained from sugar beet.
EFFECT: method provides efficient extraction of a pure betaine fraction.
