An ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS) method was developed for the determination of four β-agonists (terbutaline, clenbuterol, ractopamine, salbutamol) in braised meat. Samples were hydrolyzed by β-glucuronidase and cleaned up by an SLS solid phase extract...
COUPLING reactions (Chemistry)Three kinds of porous organic polymers (POPs) with different topological structures, named CMP, HsGY and PAF, were prepared by Sonogashira–Hagihara cross-coupling reaction with three different monomers. POPs were characterized by field emission scanning electron microscope (...

The solubility of quercetin increased with increasing CD concentration in the following order βCD < HP-βCD < SBE-βCD. Kinetic studies of DPPH indicated that the QUE–SBE-βCD complex was the most reactive form. ESR is a useful methodology for determining reactions involving quercetin free ...
a6、The hydrocarbon part of an organic molecule is fairly unreactive,so the chemistry of organic compounds is often dominated by other atoms or groups of atoms joined to the chain. There atoms or groups of atoms,whose reactions dominate the chemistry of the molecule,are called functional groups...
