Abstract: A propranolol molecule-imprinted monolithic stationary phase (MIMSP) was synthesized by in situ technique. The recognition mechanism of the polymers and the influences of some chromatographic conditions were examined by high-performance liquid chromatography (HPLC). The imprinted polymers showed much higher selectivity for β-blockers than the nonimprinted polymers (NIPs) did, which proves the successful preparation of propranolol-imprinted polymers by using an in situ technique. Then, this technique was used to prepare a molecularly imprinted polymer solid-phase extraction column to concentrate propranolol from biological samples. The results showed that the imprinted solid-phase extraction column could selectively enrich and purify propranolol from biological samples, such as plasma
