| Abstract: | Object To establish an HPLC method for the determination of scutellarin in Breviscarpin Tablet. Methods Column: Diamonsil C18 (4. 6 mm× 150 mm, 5 μm); mobile phase: acetonitrile-0.5%acetate solution (22: 78); detection wavelength was at 335 nm; temperature was at: 30 C; flow velocity was 1.2 mL/min. Results The calibration curve showed a good linearity within the range of 0-6.0μg.The average recovery was 100.43% and RSD was 0.58%. Conclusion The method is convenient, fast and reliable to operate and suitable for the quality control of Breviscarpin Tablet. |
