The inclusion complexing capacity of 21 barbituric acid derivatives with α-, β- and γ-cyclodextrins, with a water soluble β-cyclodextrin polymer and with 2,6-di-O-methyl-β-cyclodextrin was determined by chargetransfer chromatography on reversed-phase thin-layer plates. It was established that 2,6-di-O-methyl-β-cyclodextrin formed the most stable complexes with the barbituric acid derivatives followed by the water soluble β-cyclodextrin polymer. The complex forming capacities of β- and γ-cyclodextrins were similar to each other while the α-cyclodextrin formed very weak complexes. Each cyclodextrin had a different sterical requirement of substituents of the barbituric acid derivatives to fit optimally into the cyclodextrin cavity.
