title: Dextrin as excipient in pharmaceutical preparations.
abstract: The addition of commercial dextrins to aqueous solvents in thin layer chromatography on cellulose increases the Rf values of azodyes such as methyl orange. The increase is less than with cyclodextrins but shows that dextrins also form supramolecular complexes. This should be considered when dextrins are used as "inert" excipients in pharmacy.
