A simple and rapid method was developed for the separation of derivatized carbohydrates of Potentilla anserina L. using 1-naphthyl-3-methyl-5-pyrazolone (NMP) as derivatization reagent by capillary zone electrophoresis. The detection was performed with diode array at 254 nm. A 58.5 cm×50 μm i. d. (50 cm effective length) untreated fused-silica capillary was used. The optimum conditions are as follows:55 mmol/L borate buffer (pH=9.46), voltage 22 kV, column temperature at 20℃ and detection at 254 nm. The samples were atmospherically introduced with an injection time of 10 s. The results indicate that 9 NMP-derivatized carbohydrates achieve baseline resolution within 16 min under the proposed conditions. The Potentilla anserina L. sample was also analyzed under the optimum conditions.
