title: [HPCE determination of matrine in matrine liposome].
abstract: OBJECTIVE
  To establish an HPCE method for the determination of matrine in Matrine Liposome.
  
  
  METHODS
  HPCE was used. The best condition was achieved with a fused silica capillary tube( 150 cm x 75 microm), 0.25 mol/L phosphate buffer (pH 6.8), at constant voltage of 20 kV and temperature at 25 degrees C. The UV detection wavelength was 206 nm.
  
  
  RESULTS
  The calibration curve was linear in the range of 0.3-6.025 mg/ml for matrine (0.9995). The average recovery of matrine was 97.3%.
  
  
  CONCLUSIONS
  This methods is simple, quick, accurate and suitable for the quality control for Matrine Liposome.
