摘要
目的:建立RP-HPLC法测定八维钙锌片中烟酰胺、维生素B1、B2、B6的含量。方法:采用Phenom enex C18柱(150 mm×4.6 mm,5μm);流动相为庚烷磺酸钠溶液(取庚烷磺酸钠0.6 g,加冰醋酸6 mL与三乙胺1 mL,加水至1000 mL,用2 mol.L-1氢氧化钠溶液调节pH至3.80)-甲醇(80∶20);紫外检测波长为280 nm;流速为1 mL.m in-1。结果:烟酰胺的线性范围为26.463~423.40μg.mL-1(r=0.9999),平均回收率为100.8%,RSD为1.4%(n=9);维生素B1的线性范围为3.90~62.4μg.mL-1(r=0.9999),平均回收率为100.9%,RSD为1.3%(n=9);维生素B2的线性范围为4.64~74.24μg.mL-1(r=0.9999),平均回收率为99.7%,RSD为1.8%(n=9);维生素B6的线性范围为4.95~79.28μg.mL-1(r=0.9999),平均回收率为100.3%,RSD为2.8%(n=9)。结论:本方法操作简便,结果准确、可靠,可同时测定八维钙锌片中烟酰胺、维生素B1、B2、B6的含量。
Objective:To establish the method for the determination of nicotinamid,vitamin B1,vitamin B2 and vitamin B6 in compound reserpine tablets.Method:The separation was performed phenomenex C18(150 mm×4.6 mm,5 μm).Heptanesulfonic acid sodium salt-methanol(80∶20)as the mobile phase with the flow rate of 1.0 l·min-1,and 280 nm as the detective length.Results:All the results for the standards curve,the average recovery and the separation showed that the method is satisfactory.Conclusion:The method is simple,fast and accurate for analysis of Baweigaixin tablets.
