摘要
目的建立HPLC法测定兰索拉唑肠溶片的血药浓度。方法采用高效液相色谱法,色谱柱:Hypersil ODS(250 mm×4.6 mm,5μm),柱温:40℃,流动相为水∶乙腈∶正辛胺(620∶380∶1),流速:1.2 ml.min-1,检测波长:285 nm。结果兰索拉唑在0.05～2.00 mg.L-1范围内线性关系良好(r=0.999 8),平均回收率为99.48%,RSD=4.50%。结论该方法灵敏、准确、稳定,适用于兰索拉唑的血药浓度检测。
Objective To develop an HPLC method for the determination of plasma concentrations of Lansoprazole enteric-coated tablets.Methods HPLC was adopted.Hypersil ODS（250 mm×4.6 mm 5 μm） was used,with column temperature at 40℃.The mobile phase was water∶ acetonitrile∶ n-octyl amine（620∶ 380∶ 1 v/v）.The flow rate was 1.2 ml·min-1 and detection wavelength was 285 nm.Results Within the range between 0.05 and 2.00 mg·L-1,there was a good linear relationship（r=0.999 8）.The average recovery was 99.48%,and RSD was 4.50%.Conclusion The method is simple,accurate,stable and can be applied to determine plasma concentrations of lansoprazole enteric-coated tablets.
