Online sweeping-micellar electrokinetic chromatography method for separating and measuring protocatechuic acid in acute bronchitis syrup

The invention discloses an online sweeping-micellar electrokinetic chromatography method for separating and measuring protocatechuic acid in acute bronchitis syrup. In micelle capillary electrophoresis, the electrophoresis conditions are that the buffer system refers to 20mmol/L sodium dihydrogen phosphate, 80mmol/L SDS and 12.5 percent (V/V) of acetonitrile with the pH value of 2.2; the detection wavelength is 225nm; the ambient temperature is 25 DEG C. The online sweeping-micellar electrokinetic chromatography method comprises the following steps: diluting a to-be-detected standard substance and sample solution to a proper concentration by using water, wherein the separation voltage is -20kV; and performing gravity injection, wherein the injection height is 16cm, and the injection time is 60 seconds; and the detection limit of protocatechuic acid is 15.96mu g/L. The method disclosed by the invention has the beneficial effects that the online sweeping-micellar electrokinetic chromatography method has good enrichment effect and detection limit, and the method is simple, rapid, high in sensitivity and high in reproducibility and can be used for separating protocatechuic acid and measuring content of protocatechuic acid in cough medicines.
