Analysis of prostaglandins by micellar electrokinetic capillary chromatography.

This paper presents a rapid and reliable micellar electrokinetic capillary chromatography (MEKC) method to separate major prostaglandins and thromboxane B2. The running buffer was modified with sodium dodecyl sulfate (SDS). The effects of the SDS concentration on the migration behavior of analytes was also examined. Moreover, the influences of electrolyte concentration and capillary temperature...

Oroxylum indicum Seeds—Analysis of Flavonoids by Micellar Electrokinetic Chromatography

Flavonoids are bioactive constituents in Oroxylum indicum seeds, an Asian traditional remedy used for the treatment of respiratory infections. In this study the first capillary electrophoretic method for their determination is presented. By using a 25 mM borax buffer at pH 9.2 containing 10 mM SDS as detergent, the determination of seven flavonoids was feasible in only 13 min. Method validation...

Determination of gibberellic acid in fermentation broth and commercial products by micellar electrokinetic chromatography.

Micellar electrokinetic chromatography (MEKC) was developed as a method for quantitative determination of gibberellic acid (GA3) in fermentation broth and commercial products, using 25 mM disodium tetraborate as a buffer at pH 9.2 and 100 mM sodium dodecyl sulfate as a micellar phase. The baseline resolution (Rs of GA3 from other compounds in fermentation broth was achieved with Rs > 2.5. The a...

Analysis of oseltamivir in Tamiflu capsules using micellar electrokinetic chromatography.

A simple and rapid micellar electrokinetic chromatography (MEKC) method was developed for the analysis of an antiviral drug, oseltamivir, and its hydrolyzed product in Tamiflu capsules. Background electrolytes consisted of boric acid 10 mM, pH 10, and sodium dodecyl sulphate (SDS) 40 mM. The limit of detection (LOD) and limit of quantification (LOQ) of oseltamivir were 1.7 and 8.0 microg/ml, re...
