ABSTRACT
Vanillic acid (4-hydroxy-3-methoxybenzoic acid) is a phenolic acid found in many plant extracts. It is used as aflavoring and scent agent and produces a pleasant, creamy odor. It is widely used in many applications for therapeuticpurposes to flavoring agent. Molecularly imprinted polymers of vanillic acid were synthesized by precipitationpolymerization with a noncovalent approach for the extraction from blood serum. Three different imprinted polymershave been synthesized with varying molar ratio of monomer. The synthesized polymer particles were characterizedusing Fourier-transform infrared spectroscopy and scanning electron microscopy. The extraction efficiency of highlyselected imprinted polymer of vanillic acid from spiked blood serum was about 80%.
