The inclusion complex formation between Metoprolol tartarata (MeT) and beta -cyclodextrin (beta -CD) has been investigated using hyperchromic shift at lambda (max) 274.4 nm of MeT. Different parameters such as stirring time, solvent composition (aqueous and aqueous/methanol solutions with methanol content up to 50%), pH values 4.0 and 8.0 were established for optimal inclusion complex formation and confirmed two stoichiometric compositions 1:1 and 1:2. Preliminary data. on usage of MeT/beta -CD complex in reversed-phase HPLC indicate the potential application of this complex as a kind of pre-column derivatization for enantiomeric separation of beta (1)-blockers.
