Aqueous extracts of cultivated paeony root and commercial samples of paeony root powder were subjected to quantitative analysis of inorganic anions, F^-, Cl^-, Br^-, I^-, SO_4^<2->, PO_4^<3-> and NO_3^-, by means of capillary tubetype isotachophoresis using three electrolyte systems. Seventy samples of cultivated paeony root and nineteen samples of commercial one were subjected to the analysis. None of F^-, Br^- and I^- anions were detected in any of the above samples. Anions, Cl^-, SO_4^<2->, PO_4^<3-> and NO_3^- were detected in paeony root powder, each at 500 ppm. Capillary tubetype isotachophoresis requires only a small amount of sample and simple pretreatment, and thus affords a quicker and more economical method of analysis of inorganic anions than other analytical methods.
