Claims10
A method of producing D-chiro-inositol from kasugamycin, comprising the steps of:
- providing a quantity of kasugamycin;
- hydrolyzing said quantity of kasugamycin with a hydrolyzing agent under suitable time and temperature conditions so as to obtain an aqueous mixture of D-chiro-inositol and reaction products from said quantity of kasugamycin;
- passing said aqueous mixture of D-chiro-inositol and reaction products through a cation exchange medium capable of binding anionic reaction products and impurities in said aqueous mixture and an anion exchange medium capable of binding cationic reaction products and impurities;
- removing other impurities from an eluate from said cation and anion exchange medium;
- and
- obtaining D-chiro-inositol from said eluate.
