    Abstract:
    OBJECTIVE: To determine the content of dexamethasone sodium phosphate in Fuyankang cream, a preparation for treatment of various skin conditions. METHODS: Dexamethasone sodium phosphate content in Fuyankang cream was determined using high-performance capillary electrophoresis (HPCE) at the detection wavelength of 254 nm, under the optimal condition achieved with a fused-silica capillary tube (60 cm x 75 microm) and 100 mmol/L sodium tetraborate buffer (pH 9.2) at a constant voltage of 25 kV with a sampling time of 10 s at 25 degrees Celsius;. RESULTS: The calibration curve displayed good linear relationship within dexamethasone sodium phosphate concentration range of 20 to 100 microg/ ml r=0.999 8 . The average recovery of dexamethasone sodium phosphate was 99.75% n=5, RSD=1.03% . CONCLUSION: HPCE is simple, quick and sensitive in determination of dexamethasone sodium phosphate content in Fuyankang cream.
