Molecularly imprinted polymers (MIPs) were prepared by precipitation polymerization with ginsenoside Rg1 as the template molecule. The morphology of MIPs was characterized by scanning electronmicroscope (SEM) and its static adsorption capacity was measured by the Scatchard equation. Scatchard analysis revealed that the homogeneous binding sites were formed in the polymers. The application of MIPs with high affinity toward the template molecule might offer a novel method for the enrichment and determination of active compounds in the traditional herbal medicine.

To establish a novel method for preparing molecularly imprinted polymers for ginsenoside Rg1 with better character contrast to previous studies, we have prepared novel surface molecular imprinted polymers (S-MIPs) using ginsenoside Rg1 as the template molecule, Acrylamide (AM) as the functional monomer, and silica gel as the carrier. The morphology of S-MIPs was characterized by scanning electron microscope (SEM) and its static adsorption capacity was measured by the Scatchard equation.

Environmentally Friendly Method

Molecularly imprinted polymers (MIPs) are synthetic materials that can be the environmental protection extraction method in TCM research and industry. They can overcome the defects of traditional extract methods and environmental pollution. In our research, MIPs were prepared by precipitation polymerization with neuro-protective picroside I and ginsenoside Rb1 as the template molecule. Moreover, the morphology of MIPs was characterized by electron microscope scanning and the static adsorption capacity was measured by the Scatchard equation. Finally, MIPs were made into MIP-SPE columns to enrich the template molecule and its analogues comparing with C18-SPE column and the results show that MIPs have good affinity and selectivity towards the Rb1 and Picroside I in SPE columns. This research may offer a more environmentally friendly method to extract active compounds in the traditional herbal.

Molecular imprinted polymer micrcosheres (MIPMs) were prepared through precipitation polymerization by andrographolide using as the template molecule. The morphologies of synthesized MIPMs were characterized by scanning electronmicroscope (SEM). Systematic investigations of the influences of key synthetic conditions, including functional monomers, cross-linkers and porogens, on the morphologies, yields and the recognition properties of the MIPs were conducted. The results indicated that the morphologies of MIPs with DVB as cross-linker was perfect, but their binding affinity is lower than that of MIPs with TRIM or EDMA as cross-linkers. And particle size of MIPs with TRIM as cross-linkers is small but with high binding affinity. Scatchard analysis revealed that the homogeneous binding sites were formed in the polymers. The application of MIPs with high affinity and excellent stereo-selectivity toward andrographolide in solid-phase extraction (SPE) column might offer a novel method for the enrichment and determination of terpenoids compounds in the traditional herbal medicine.

First Time

A method of purifying cyclododecyl 2,4-dihydroxybenzoate as a potential replacement template molecule for preparation of molecularly-imprinted polymers for isolation of zearalenone in urine was developed. Full physicochemical characteristics of cyclododecyl 2,4-dihydroxybenzoate for the first time included crystallographic analysis and molecular modelling, which made possible the determination of the similarity between the cyclododecyl 2,4-dihydroxybenzoate and zearalenone molecules. The obtained molecularly-imprinted polymers show very high in vitro selectivity towards zearalenone due to specific interactions (e.g., hydrogen bonding, molecular recognition interaction). The achieved extraction recovery exceeds 94% at the tested concentration levels (20–500 ng·mL−1) with a relative standard deviation below 2%. Immunosorbents were found to have lower recoveries (below 92.5%) and RSD value between 2 and 4% for higher concentrations of the studied substance (400 ng·mL−1).
