摘要
目的建立一种简便、灵敏的测定方法来检测甲磺酸达比加群酯胶囊的含量。方法采用高效液相色谱法测定甲磺酸达比加群酯胶囊中主药的含量,色谱柱:ODS C_(18)(250 mm×4.6 mm,5μm),流动相∶甲醇-水(75∶25,水中加0.1%三乙胺),检测波长:323 nm,流速:1.0 mL·min^(-1);柱温:35℃;进样体积:10μL。结果甲磺酸达比加群酯在0.5~10μg·mL^(-1)范围内线性关系良好(R^(2)=0.9999),平均回收率为98.93%,RSD为0.46%。结论该方法操作便捷、灵敏度高,结果准确,可用于甲磺酸达比加群酯胶囊中甲磺酸达比加群酯的含量测定。
OBJECTIVE To establish a simple,sensitive determination of dabigatran etexilate mesylate capsules.METHODS HPLC method was adopted.The separation was performed on a ODS C_(18)(250 mm×4.6 mm,5μm),column with mobile phase consisted of methanol-water(75∶25,0.1%triethylamine in water)and the detection wavelength was 323 nm.The flow rate was 1.0 mL·min^(-1).The column temperature was 35℃.The injection volume was 10μL.RESULTS The linear range of dabigatran etexilate mesylate was 0.5-10μg·mL^(-1)(R^(2)=0.9999).The average recovery was 98.93%(RSD=0.46%,n=9).CONCLUSION The method is simple and accurate,which can be used in the quantitative determination of dabigatran etexilate mesylate in capsules.
