【Abstract】 AIM A HPLC method was established for the determination of Matrine and Glucose Injection. METHODS Matrine can be separated on SymmetryShield column(C 18 5 μm 250×4 6 mm) with a mixture of phosphate buffer(phosphoric acid 2 5 ml, triethylamine 2 ml,was solved with water and diluted to 1000 ml) acetonitrile(90∶10) as mobile phase and detected at 210 nm. The flow rate was 1 0 ml/min. RESULTS The standard curve was linear in the concentration range 13 99～97 93 g·L -1 and the correlation coefficient was 0 999 6 . The average recovery and the relative standard deviation was 99 44% and 1 16% respectively. CONCLUSIONS The method is simple,rapid,accurate and reliable.更多还原
