Abstract:Objective To establish a HPLC method for determination of berberine hydrochloride in Dongbai Tonglin Heji. Methods The separation column of Kromasil C18(150 mm×4.6 mm,5 μm) was used. The mobile phase was acetonitrile and 0.05 mol/L NaH2PO4 solution(pH was adjusted to about 3 with phosphoric acid). The flow rate was 1.0 ml/min with the column at room temperature and the detection wavelengths at 345 nm for berberine hydrochloride. Results The linear range of berberine hydrochloride was 1.00~50.00 μg/ml(r=0.999 6). The average recoveries of berberine hydrochloride were 104.70%(RSD 1.60%, n=5). Conclusion This method is accurate, sensitive, selective and reproducible. It provides an alternative method to improve the quality control of Dongbai Tonglin Heji. |
