【Abstract】 Objective:To establish a method for determination of the berberine hydrochloride content in shuanghuangbu sustained release medicinal strips. Methods: RP-HPLC was used to determine the berberine hydrochloride content in shuanghuangbu sustained release medicinal strips. Kromasil C18(100mm×4.6mm,5μm) was used as the stationary phase and acetonitrile-0.05M potassium dihydrogen phosphate(28:82) was taken as the mobile phase ,the detection wavelength was at 263nm . Results: The standard curve was excellent linear in the range of 2.52～50.40μg/ml and with the correlation coefficient of 0.9999. The average recovery was 99.8%(RSD=1.14%). The berberine hydrochloride content in shuanghuangbu sustained release medicinal strips was 5.64mg/g(n=5). Conclusion: This method is sensitivity, reproducibility and stabitity, and can be used as a quantitative method for this preparation.更多还原
