RESUMO
Objective To determine the content of berberine hydrochloride in Shaoyao decoction. Methods HPLC was performed on an Agilent XDB C18 column by using acetonitrile-0.05 mol/L potassium dihydrogen phosphate-triethylamine (30∶70∶0.14) as mobile phase at a flow rate of 1.0 mL/min, the column temperature was 25 ℃ and the UV detection wavelength was 345 nm. Results Berberine hydrochloride showed a good linearity redationship in the range of 0.07~1.40 ?g. The average recovery was 98.63% (n=6, RSD=1.21%). The average content was 1.55%. Conclusion The method is simple and accurate, with good repeatability, and can be used for the quality control of Shaoyao decoction.
