Abstract: OBJECTIVE To study the separation of mimic-mixed 7 kinds of antraquinone derivatives. METHODS Micellar electrokinetic capillary chromatography with additive of organic solvent was used. RESULTS Emodin,chrysophanl,physcion,rhein,emodin-8-o-β-D-glucopyranoside,aloe-emodin,and Physcion-8-o-β-glucopyranoside were separated successfully in 16 min in the buffer of 25 mmol/L H 3BO 3(pH9.2)containing 25mmol/L SDS and 10% acetonitrile. CONCLUSION Micellar electrokinetic capillary chromatography with additive of organic solvent has potential advantages on separation of anthraquinone derivatives.
