Abstract: | 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. |
