A simple, reliable and reproducible method was developed for determination of psoralen and isopsoralen in several traditional Chinese medicines, such as Shouwu Pian, Gubenkechuan Pian, was described in this paper. It was based on capillary zone electrophoresis with amperometric detection (CZE-AD). A carbon-disc electrode was used as working electrode. The optimal conditions of separation and detection...
The molecular imprinted technique was applied for the preparation of a polymer selector by using methacrylic acid as the functional monomer, EDMA as the crosslinker, AIBN as the initiator and aminoantipyrine as the template. The adsorption isotherms of aminoantipyrine, antipyrine, pyrazolone and the competitive adsorption isotherms of aminoantipyrine and antipyrine on the imprinted stationary phase...
