摘要: A molecularly imprinted polymer (MIP) was synthesized by precipitation polymerization with tanshinone IIA as the template and used an adsorbent for solid-phase extraction (SPE). simulation employed to predict most suitable solvent, functional monomer, molar ratio of monomer. The obtained materials were evaluated transmission electron microscopy, scanning rebinding experiments, exhibiting good morphology, high binding IIA. Compared nonimprinted polymers, material exhibited a higher sorption capacity, up 34.09 µmol g−1, better selectivity its structural analogs. successfully SPE coupled high-performance liquid chromatography determination IIA, cryptotanshinone, I in fortified serum. mean recoveries between 91.5% 95.1% relative standard deviations less than 4.9...
