Application of computational simulation and spectral analysis in preparation of Tanshinone IIA imprinted polymer / 中草药

ABSTRACT

To prepare Tanshinone IIA (TSIIA) molecularly imprinted polymers (MIPs) with affinity and high selectivity to TSIIA and study its mechanism. Taking TSIIA as the template molecular, synthesizing the MIPs at the surface of silica nanoparticles by grafting copolymerization in the toluene solution. A molecular modeling approach was used to elucidate template-monomer interaction. The interaction between template molecule and functional monomer was studied by UV spectrometry. The theoretical molar ratio of template-monomer was 1∶3 and methyl acrylic acid (MAA) was a better functional monomer than acrylamide (AAM) for MIPs synthesis. The MIPs can be used for the extraction and separation of TSIIA.
