Objective: To establish a method for simultaneous determination of puerarin
liquiritin
baicalin and berberine hydrochloride in Gegenqinlian Micropills. Method: RP-HPLC was applied on a Kromasil-C18 column (4.6 mm×250 mm
5 μm) with methanol-phosphate buffer as mobile phase by gradient elution. The flow rate was 1.0 mL· min-1
and the detection wavelength was set at 275 nm. Result: The methodology of 4 components met the requirements with no interference of negatives. Conclusion: The method established is easy
accurate with high specificity
which can provide the base for the quality control of Gegenqinlian Micropills.
