| 中文摘要: |
| 目的建立高效液相色谱法(HPLC)用于测定盐酸丙酰左卡尼汀片中盐酸丙酰左卡尼汀的含量。方法 色谱柱为Thermo Hypersil Aps-2氨基柱(4.6 mm×250 mm,5 μm),流动相为0.05 mol·L-1磷酸二氢钾缓冲液-乙腈(35∶65),流速1.0 mL·min-1,柱温30℃,检测波长205 nm。结果 盐酸丙酰左卡尼汀在0.505 0～5.050 2 g·L-1(r=0.9999)浓度范围内线性良好,平均加样回收率为100.1%。结论 该文建立的方法专属性强、重复性好、结果准确可靠,可用于盐酸丙酰左卡尼汀片的质量控制和评价。 |

| Objective To establish an HPLC method for determining the content of propionyl L-carnitine hydrochloride in propionyl L-carnitine hydrochloride tablets.Methods The column was on a Thermo Hypersil Aps-2 amino column (4.6 mm×250 mm,5 μm)and 0.05 mol·L-1 solution of potassium dihydrogen phosphate-acetonitrile (35∶65) was employed as the mobile phase.The flow rate was 1.0 mL·min-1 with UV detection wavelength at 205 nm and the column temperature was kept at 30℃.Results The linear range of propionyl L-carnitine hydrochloride was within 0.505 0 and 5.050 2 g·L-1(r=0.999 9).The average recovery was 100.1%.Conclusion The method is of high specificity,repeatability and accuracy,and it can be used for the quality control and evaluation of propionyl-L-carnitine hydrochloride tablets. |
