✦ Synopsis

A micellar electrokinetic capillary chromatographic method for the separation of anthraquinone positional isomers was established. The running electrolytes used in this method were 0.03 M sodium dodecyl sulphate (SDS) in 0.03 M borate buffer (pH 9) containing 10% acetonitrile for dihydroxy-and dihydroxy-methoxy-methylanthraquinones, 0.08 M SDS in 0.03 M borate buffer (pH 9) containing 10% acetonitrile for dimethoxyanthraquinones, and 0.03 M SDS in 0.08 M borate buffer (pH 8) containing 10% acetonitrile for hydroxy-methoxy-and dihydroxymethylanthraquinones, each with an applied voltage of 20 kV. This method is simple, rapid and reproducible.

A micellar electrokinetic capillary chromatographic method was set up for the separation of five anthraquinone derivatives in rhubarb. Optimization of pH and sodium deoxycholate(SDC) concentrations was studied, which showed that 50 mM H3BO3-NaOH(pH 11) containing 25 mM SDC could separate the five in
