摘要
采用高效液相色谱法测定盐酸度洛西汀肠溶片的含量与有关物质。色谱柱:Thermo ODS-2HYPERSIL;流动相:乙腈-0.05 mol·L^-1醋酸胺溶液(55∶45,用三乙胺调节pH值至9.0);流速:1.0 mL·min^-1;检测波长:230 nm。结果在2.5~25μg·mL^-1范围内线性关系良好(r=0.9999,n=6),平均回收率为98.7%,RSD为1.5%。本法专属性强、灵敏、准确,可用于盐酸度洛西汀的含量及有关物质的测定。
A HPLC method was established for the determination of Duloxetine Hydrochloride Enteric -coated Tablets and its Related Substances. The chromatogram columniation were Thermo ODS- 2HYPERSIL. Acetonitrile- 0.05 mol·L^-1 Ammonium acetate (55: 45, pH = 9.0 adjusted by Triethylamine) was mobile phase. The flow rate was 1.0 mL·min^-1. The detection was carried out with an ultraviolet detector at 230 nm. The standard curve was linear in the range of 2.5~25μg·mL^-1. The average recovery was 98.7%, RSD was 1.5%. The method is sensitive and accurate. It can be used for the quantitative determination of Duloxetine Hydrochloride Enteric-coated Tablets and its Related Substances.
