摘  要:目的:建立高效液相色谱法测定抗金葡颗粒中黄芩苷的含量。方法:采用Diamonsil ^TMC18(250mm×4.6mm,5μm),以甲醇-水-磷酸(47:53:0.2)为流动相;检测波长为280nm;流速:1.0ml/min;进样量:10μl。结果:黄芩苷在0.051744-0.34496μg范围内线性良好(r=0.99997),平均回收率为101.13%,RSD为1.6%。结论:本法准确、快速、重现性好,可有效控制该制剂质量。Objective : To establish an HPLC method for determination of baicalin in Kangjinpu Granule. Methods : The chromatographic separation was performed on a DiamonsilTM Cls column(250 mm × 4.6 mm, 5 μm) with the mobile phase consisting of methanol -water-phosphoric acid(47: 53: 0.2). Detection wavelength was set at 280 rim; The flow rate was 1.0 ml/min. Results: The linear range were 0.0517 44 -0. 344 96 μg( r = 0. 999 97 ). The average recovery was 101.13 % with RSD 1.6%. Conclusion: The methed is accurate, rapid and repeatable. It is suitable for the qualitv control of Kangjinou Granule.
