Extraction of Catechin as a Flavonoid Compound via Molecularly Imprinted Polymers

The aim of this study is synthesis molecularly imprinted polymers (MIPs) and evaluation for extraction catechin. Catechin a bioactive compound which found abundantly in green tea. In paper, MIPs was synthesized by precipitation polymerization technique catechin, acrylic acid trimethylolpropane trimethacrylate as template, functional monomer cross-linker molecular ratio (1:12:12), respectively. Surface morphology the scanning electron microscopy (SEM) demonstrated spheres with nanometric scale. Fourier transform infrared spectroscopy (FTIR) showed that catechin molecule captured network copolymers. Porosity were analyzed using Brouneur Emmet Teller (BET) technique. Based on BET analysis, specific surface area 45.5 m2.g-1 while it 42.2 non-imprinted (NIPs). It means imprinting process carried out successfully. Adsorption properties characterized too. best binding capacity reported equal to 440 mg. g-1 750 ppm feed concentration whereas 84mg.g-1 quercetin (similar structure catechin). confirms technology can be introduced good candidate separation satisfactory result selectivity. evaluated natural extract tea high-performance liquid chromatography (HPLC) device similar results obtained. According above mentioned results, pre-concentration compounds from medicinal plants suggested via
