A micellar electrokinetic capillary chromatographic method was set up for the quality control of rhubarb and its preparations. Anthraquinone derivatives were separated successfully within 10 min in the buffer solution of 50 mmol/L H 3 BO 3 -NaOH (pH 11) containing 25 mmol/L sodium deoxycholate. The
