Abstract: Molecularly imprinted polymer(MIP) stationary phases against caffeine and against theophylline were prepared. Separation abilities of the phases were investigated by HPLC. The results showed that the theophylline based MIPstationary phase is highly selective to theophylline, and base-lined separation of caffeine and theophylline was achieved. However, the caffeine based MIPstationary phase did not possess specific selectivity to the template molecule, caffeine. MIPwith specific selectivity to template molecule can only be prepared when interactions between template and monomer go together.

Key words: High performance liquid chromatography, Molecular imprinted polymer, Caffeine, Theophylline
