| Abstract: | Using self-constructed electrochemical detection system,buddleoside was detected by high performance capillary electrophoresis(HPCE).Several parameters affecting the determination were studied,including effects of potential of working electrode,organic concentration,running buffer,acidity and working voltage.Under the optimal conditions,a linear relationship between the peak height(Y) and the mass concentration(c) was obtained in the range of 2.0-80 mg/L with a correlation coefficient of 0.999 6.The determi... |
