“…Watabe developed a column-switching HPLC system, and achieved automatic microanalysis of bisphenol A at ultralow concentrations (below 1 ng/L) using electrochemical detection [36]. On the basis of column-switching HPLC system, Watabe also presented a HPLC-ED method [18] and a HPLC-MS method [37] for the analysis of bisphenol A in environmental water, respectively, using molecularly imprinted polymer as an on-line pretreatment device.…”

“…However, interactions between a template molecule and a functional monomer could be interfered since water is used as a continuous phase. MIPs for bisphenol A (BPA) [22,23] were prepared using 4-vinylpyridine (4-VPY) or 2-vinylpyridine as a functional monomer and applied for SPE of BPA in river water samples.…”

This review article deals with molecularly imprinted polymers (MIPs) as affinity-based separation media for sample preparation. An over view of two types of MIPs (molecularly imprinted particle and monolith) used for the sample preparation and modes of molecularly imprinted SPE (online mode, offline mode, on-column extraction, SPME, and microextraction in packed syringe) is given, focusing on the advantages and disadvantages of these types and modes. Next, problems (template leakage and incompatibility with aqueous conditions) associated with molecularly imprinted SPE and how to overcome those problems are described. Finally, pharmaceutical, food, bioanalytical, and environmental application of molecularly imprinted SPE will be discussed.

“…Most of the MISPE applications have focused on extracting compounds from biological [13] and environmental samples [14], while a small number of studies on drug [15], food [16], and other real samples. Molecularly imprinted polymers have good affinity and selectivity for the molecule of interest.…”

Original PaperSolid-phase extraction of ursolic acid from herb using b-cyclodextrin-based molecularly imprinted microspheres A new method was employed to solid-phase extract ursolic acid from Ilex kudingcha C. J. Tseng using molecularly imprinted microspheres (MIMs) as the sorbent. Using a surface molecular imprinting technique, MIMs for ursolic acid were prepared with bonded b-CD and acrylamide in combination based on functionalized poly(glycidyl methacrylate) microspheres (F-PGMA). Compared with non-MIMs (NIMs), MIMs showed high adsorption capacity, significant selectivity, and good site accessibility for ursolic acid. The maximum static adsorption capacities of the MIMs and NIMs for ursolic acid were 42.5 and 4.9 lmol/g, respectively. Chromatographic analysis shows that ursolic acid and oleanolic acid could be separated well when MIMs were used as the stationary phase of HPLC. The conditions of molecularly imprinted SPE (MISPE) of ursolic acid from the herb extract were optimized using different concentrations of ethanol solutions as loading, washing, and eluting solutions. The successful extraction of ursolic acid by MIMs provided a possible innovative approach to separate ursolic acid from herb.
