摘  要:目的:建立乳结消片中黄芩苷的含量测定方法。方法:高效液相色谱法,色谱柱为VP—ODS C18柱(250mm×4.6mm,51μm);流动相:乙腈-0.2%磷酸溶液(30:70);流速:1.0mL·min^-1;检测波长:280nm;柱温:25%,进样量:20μL。结果:黄芩苷在0.44~4.4μg范围内线性关系良好(r=0.9999),平均加样回收率为100.09%(RSD=1.03%)。结论:本方法操作简便、准确快速、重现性好,可用于乳结消片的质量控制。Objective: To establish an HPLC method of content determination of baicalin in Rujiexiao tablets. Method : VP - ODS C18 (250mm × 4. 6mm, 5μm) was used as chromatographic column, acetonitrile - 0. 2% phosphoric acid (30:70) as mobile phase, with a flow rate at 1.0mL min^-1. The column temperature was 25℃, the detection wavelength at 280nm, and the sample size was 20μL. Results: The calibration curve of baicalin was linear within the range of 0. 44 - 4. 4μg ( r = 0. 9999 ), the average recovery was 100. 09% ( RSD = 1.03% ). Conclusion: The method is simple, accurate, reproducible and suitable for the quality control of rejiexiao tablets.
