Abstract

Abstract Cyclodextrins, their derivatives and products of their partial hydrolysis are clearly separated by chromatography on silica gel by mobile phases containing aqueous ammonia and organic solvent (acetonitrile or 1-propanol). This system allows separation of compounds with different numbers of substituents on cyclodextrin, but does not allow the separation of isomers; the system can be used both for thin-layer chromatography and for preparative column chromatography. The isomers in the fraction thus obtained can be in some cases separated, after peracetylation, by chromatography on silica gel using a mobile phase consisting of methanol and dichloromethane. This chromatographic sequence potentially yields derivatives of cyclodextrins in quantities which enable evaluation of their solubilization and biological properties.
