摘　　要：目的建立清胃丸中黄芩苷的含量测定方法。方法采用RP-HPLC法,以甲醇-水-磷酸(47∶53∶0.2)为流动相;检测波长为315nm。结果黄芩苷在(6.18～80.34)μg/mL(r=0.9998)范围内线性关系良好;平均回收率为99.18%,RSD为0.75%(n=6)。结论本文方法简便可靠,专属性强,重现性好,可用于清胃丸的质量控制。Objective To establish the determination method of Baicalin in Qingwei Pills. Methods HPLC was used and methanol-water-phosphoric acid （47：53：0.2） mixture as a mobile phase. The detection wavelength was set at 315 nm. Results Baicalin showed a good linear relationship at a range of（6.18-80.34）μg/mL,t=-0.9998. The average recovery was 99.18% and RSD was 0.75%（n=6）. Conclusion The method is simple with good reproducibility and can be used for Qingwei Pills.
