| Abstract: | Objective: To establish a HPLC method for the determination of puerarin in Gelian Zhixie granule. Methods: The chromatographic conditions were Beckman ODS C 18 colum,mobile phrase of methonal -2.5% acetic acid (25∶75),flow rate of 1.0 ml·min -1 and detection wavelength at 250 nm. Results: The standard curve was linear over the range of 0.1～1 μg with the correlation coefficient 0.9998.The average recovery was 98.64% with RSD=1.72%(n=5). Conclusion: The HPLC method is sensitive, rapid and accurate. It can be used to control the quality of Gelian Zhixie granule. |
