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%.
Conclusion:
This methods is simple, quick, accurate and suitable for the quality control for Matrine Liposome.
