متن کاملQuantitative Analysis of Eight Cephalosporin Antibiotics in Pharmaceutical Products and Urine by Capillary Zone Electrophoresis
A simple and rapid capillary zone electrophoretic (CZE) method has been established for separation and quantification of a mixture of eight cephalosporins – cefadroxil (CFL), cefixime (CIX), cefuroxime sodium (CFR), ceftriaxone sodium (CTR), ceftizoxime (CFT), cefaclor (CFC), cefradine (CFD), and cefotoxime (CTA). Conditions affecting the separation were pH, buffer concentration, and applied po...
متن کاملFast Separation and Determination of Flavonoids in Honey Samples by Capillary Zone Electrophoresis
Flavonoids have crucial applications in the biological and physiological fields. Honey, as an important sweet food made by bees, is rich in flavonoids. In this paper, the analytical method for flavonoids determination in different sorts of honey from different geographical locations was developed by capillary zone electrophoresis with direct ultraviolet detection. With a running buffer (borate,...
متن کاملAnalysis of micafungin in serum by capillary zone electrophoresis.
A method is developed for measuring the concentration of micafungin, an echinocandin antifungal agent, in serum, using capillary zone electrophoresis. With a 0.1M borate buffer (pH 10.0) as the run buffer, detection is carried out at 200 nm. Pretreatment is performed by adding acetonitrile to serum (1:2) for deproteinization, allowing the supernatant fluid to be taken for measurement. The detec...
