Capillary zone electrophoresis (CZE) with multi-wavelength detection has been used for the separation of the main alkaloids fromEschscholtzia californica. Optimum separation has been achieved with a fused silica capillary tube and a running electrolyte at pH 2.8 prepared from a 40 mM solution of citric acid and a 80 mM solution of Na2HPO4. The applied voltage was 20 kV and the capillary thermostating temperature was kept constant at 10°C.
