A method was developed to determine the substitution pattern of O-(2-hydroxy-3-trimethylammonium)propyl ethers of starch. As model compounds cationic cyclomaltoheptaose and cyclomaltooctaose were prepared. After cleavage of the glucosidic linkages by methanolysis und subsequent permethylation, the p
