Objective: To establish a method for determining the contents of ferulic acid(FA) in dandelion by high-performance capillary electrophoresis (HPCE). Method: Dandelion was determined at 328nm using high-performance capillary electrophoresis (HPCE)
under the optimized conditions achieved with a elastic fused-sillia capillary tube(75 μm×57/50 cm)and 20 mmol ·L-1borate running buffer solution (pH 9.18) at a constant voltage of 18 kV and injecting pressure time of 5 s at 25 ℃. Result: FA was linear within the range of 0.002 to 0.012 g ·L-1 ( r =0.999 8). The average recovery 98.22%
RSD 1.78%. Conclusion: This method is simple
rapid
accurate and good repeatability in separation and determination of FA in Dandelion.
