Objective: To establish an HPCE method for determination of the content of three flavonoids in Oxytropismyriophylla from different areas. Method: High-performance capillary electrophoresis with an elastic silica capillary (75 μm×50 cm) was used.The electro-injection time was 15 s
voltage 18 kV
capillary temperature at 25 ℃
and the detection wavelength at 283 nm.The electrolyte buffer was composed of 0.25 mol·L-1 borax with 30% acetonitrile. Result: Content of three flavonoids in Oxytropismyriophylla from different habitats varied greatly.All calibration curves showed good linear regression (r≥0.999 6) within the tested range.All average recoveries were more than 96.00% and RSD less than 2.0%. Conclusion: This experiment has established an HPCE method which can become a quality control access of Oxytropismyriophylla.
