SYNTHESIS OF MOLECULARLY IMPRINTED POLYMER FOR DETERMINATION OF DILTIAZEM BY EXPERIMENTAL METHOD
Background & Aims: In this study, a magnetic molecular imprinted polymer was used to measure the diltiazem drug. Based on the structure and pharmaceutical agent group, methacrylic acid was selected as a monomer for Diltiazem. Ethylene glycol de-methacrylate and azobisisobutyronitrile were used as cross-linkers and polymerisation initiators, respectively. Also, chloroform was used as a porogenic...
متن کاملBioconversion of (-)-epicatechin, (+)-epicatechin, (-)-catechin, and (+)-catechin by (-)-epigallocatechin-metabolizing bacteria.
Bioconversion of (-)-epicatechin (-EC), (+)-epicatechin (+EC), (-)-catechin (-C), and (+)-catechin (+C) by (-)-epigallocatechin (-EGC)-metabolizing bacteria, Adlercreutzia equolifaciens MT4s-5, Eggerthella lenta JCM 9979, and Flavonifractor plautii MT42, was investigated. A. equolifaciens MT4s-5 could catalyze C ring cleavage to form (2S)-1-(3,4-dihydroxyphenyl)-3-(2,4,6-trihydroxyphenyl)propan...
متن کاملAre molecularly imprinted polymers (MIPs) beneficial in detection and determination of mycotoxins in cereal samples?
The process of matrix clean-up and extraction of analytes has a significant influence on the detection and determination of the analyte, especially in trace amounts. Molecularly imprinted polymers (MIPs) are solid particles that can absorb specific molecules regarding the template molecule used in the synthesis process of each type of MIP. As a result, they can be used in more effective and mor...

متن کاملUrinary excretion of catechin metabolites by human subjects after red wine consumption.
Little is known about flavonoid metabolism and excretion in man. In the present study, the urinary excretion of a major flavonoid in wine, catechin, and its metabolites, were measured after nine human subjects each consumed 120 ml red wine (RW) on one day and de-alcoholized red wine (DRW) on a separate day. Both the RW and DRW contained 120 (SEM 3) micromol catechin (35 mg). GC-MS analyses of t...
