Abstract:
OBJECTIVE:To determine the content of shikonin in Arnebia euchroma by HPCE-UV.METHODS:The separation was performed on uncoated fused silica capillary column (53 cm?50 ?m ID,46 cm effective length).2.0 mmol?L-1 H3BO3,6.0 mmol?L-1 triethylamine buffer solution and 5.0 mmol?L-1?-CD was used as background electrolyte,14 kV separation voltage and time of gravity injection 15 s (25 cm).The detection wavelength was set at 516 nm.RESULTS:The linear range of shikonin was 7.2~36.0 ?g?mL-1(r=0.999 0) with an average recovery of 100.15%(RSD=1.68%,n=6).CONCLUSION:The method is convenient,rapid,accurate and reliable for the content determination of shikonin in A.euchroma.
