摘要
目的:建立复方利血平片中维生素B_1、维生素B_6、泛酸钙和氢氯噻嗪含量测定的HPLC法。方法:采用phenomenex的Synergi Hydro-RP色谱柱(150 mm×4.6 mm,4 μm),以乙腈、0.02 mol·L^(-1)磷酸氢二钾溶液和0.005 mol·L^(-1)庚烷磺酸钠(用磷酸调节pH至3.0±0.05)为流动相,采用梯度洗脱,流速为1.0 mL·min^(-1),用二极管阵列检测器检测,检测波长210nn,柱温36℃。结果:维生素B_1的线性范围为7.752~77.52 μg mL^(-1)(r=0.9992),精密度RSD为0.99%(n=7),重现性RSD为1.62%(n=7),平均回收率为98.63%,RSD为1.59%(n=9);维生素B_6的线性范围为7.580~75.80μg·mL^(-1)(r=0.9995),精密度RSD为0.62%(n=7),重现性RSD为1.17%(n=7),平均回收率为99.17%,RSD为1.26%(n=9);泛酸钙的线性范围为7.904~79.04 μg·mL^(-1)(r=0.9997),精密度RSD为0.58%(n=7),重现性RSD为0.95%(n=7),平均回收率为98.37%,RSD为0.92%(n=9);氢氯噻嗪的线性范围为25.62~256.2 μg·mL^(-1)(r=0.9995),精密度RSD为0.19%(n=7),重现性RSD为1.36%(n=7),平均回收率为99.12%,RSD为1.06%(n=9)。结论:本方法操作简便,结果准确、可靠,可同时测定复方利血平片中维生素B_1、维生素B_6、泛酸钙和氢氯噻嗪的含量。
Objecttive:To establish the method for the determination of VitaminB1, VitaminB6, Pantothenic acid and Hydrochlorothiazide in Compound Reserpine Tablets. Method:The separation was performed on phenomenex Synergi Hydro -RP column(4.6 mm × 150 mm,5 μm)using gradient elution with acetonitrile 0. 02 mol·L^-1potassium dihydrogen phosphate and 0. 005 mol·L^-1 heptanesulfonic acid sodium salt as mobile phase;the flow rate was 1.0 mL·min^-1 The detection was set at 210 nm and the column temperature was maintained at 36 ℃. Resuits:ALL the results for the standards curve, the average recovery and the separation showed htat the method is satisfactory. Conclusion:The method is simple, fast and accurate for analysis of Compound Reserpine Tablets .
