dcterms:description
A simple and rapid capillary zone electrophoresis (CZE) method for the determination of aristolochic acid (AA) in dietary supplements and selected herbs is described. A clear separation of AA from other sample constituents was achieved within 5 minutes without any sample clean up. A mixture of 20 mM-morpholinethanesulphonic acid + 10 mM{BisTrisPropane + 0.2% hydroxyethylcelullose in 10% methanol serves as a background electrolyte. The linearity, accuracy, intra-assay and detection limit of the developed method are 200{6000 ng/mL, 95{103%, 3.5%, and 50 ng/mL, respectively. Ease of use, su+cient sensitivity and low running cost are the most important attributes of the CZE method. The proposed CZE method was compared with HPLC.
