Patent Title: Lamivudine molecularly imprinted solid phase extraction column prepared by using template substituting method and applications thereof
Publication date: 2011
Publication number: CN102008946

Abstract: The invention relates to the preparation of an absorption material and the application to medicament separation and enrichment, in particular to the preparation methods of a Lamivudine molecularly imprinted polymer and a Lamivudine molecularly imprinted solid phase extraction column and the applications thereof. The Lamivudine esterified ester is obtained through esterification synthesis. The molecularly imprinted polymer is synthesized by using the Lamivudine esterified ester as a template, methacrylic acid as a monomer, trimethoxy propane trimethyl acrylate as a crosslinker and chloroform as a porogen by adopting a body polymerization method; and molecularly imprinted polymer particles are uniformly filled in the solid-phase extraction column to obtain the Lamivudine molecular imprinting solid-phase extraction column. The invention realizes the efficient separation, enrichment and purification of Lamivudine in a biological sample and has high selectivity as compared with traditional related technologies, such as a common solvent extraction method, a C18 solid-phase extraction method, and the like. Moreover, the Lamivudine molecularly imprinted solid phase extraction column has low cost by being repeatedly used and can become a necessary method in the Lamivudine pretreatment in biological samples.
