| Abstract: | Objective: To develope a method for determining baicalin in Huangqin Tablets. Methods: The ODS C18 col umn (5 μm, 4.6 mm×150 mm) was used, the mobile phase was methanol-water-phosphoric acid (47:53:0.2) at the flow rate of 1.0 ml/min, the detective wavelength was 280 nm. Results: The linear range of baicalin concentration was 9.4-188.0 μg/ml (r=0.999 7), the average recovery was 99.6% with a RSD of 1.32% (n=6). Conclusion: The method is simple, fast and ac-curate. It can be used for the quality control of Huangqin Tablets. |
