| 中文摘要 | determination of aesculin (al) and aesculetin (at) by capillary electrophoresis with end-column amperometric detection using a 33 mu m microdisk carbon fiber electrode is described. the hdvs, the effect of ph, buffer concentration, injection voltage, injection time and separation voltage on the peak current response (i(p)) of the analytes and the number of theoretical plates (n) were studied. the method has high sensitivity and good reproducibility. under the optimum condition - 10 mm, ph 9.00 phosphate buffer, 4 s at 9 kv injection, separation at 15 kv and +1.0 v as the detection potential - low detection limits (s/n = 3) of 0.06 and 0.3 mu m were obtained for al and at, respectively. the calibration curve was linear over three orders of magnitude. the relative standard deviations (n = 15) of peak current and migration time were 3.9% and 4.6%, and 0.96% and 0.75% for 15 consecutive injections of 5 mu m al and at, respectively. the use of this method for the separation and detection of the two compounds present in the traditional chinese medicine and human urine samples is also reported.
