Abstract: A cyclodextrin-modified capillary zone electrophoresis was developed for the determination of four bioactive components in Rhubarb. Effects of pH, b-CD concentration and organic modifier content on the migration and separation of the components were studied. The four components were separated in the running buffer of 50 mmol/L NaOHH3BO3 (pH 10.7) containing 10 mmol/L b-CD and 12.5% v/v ethanol. The analytical performance of the method was tested with respect to linearity response, precision and recovery. The determination of two commercial Rhubarb samples under the optimized conditions showed a satisfactory result.
Keywords: Cyclodextrin-modified capillary zone electrophoresis; Rhubarb; Anthraquinone derivatives
