Abstract
Methods of capillary electrophoresis (capillary zone electrophoresis, micellar electrokinetic chromatography, and microemulsion electrokinetic chromatography) were compared in determining polyphenolic antioxidants and alkaloids in black and green tea. It was shown that reverse-flow micellar electrokinetic chromatography (RF-MEKC, pH < 2.5) using reversed pola rity is most preferable for the rapid simultaneous determination of catechols and caffeine. The detection limit was 1 mg/L.
