【Abstract】 Objective: To establish a HPLC method for deter m ining orientin and vitexin in Trollius chinesis preparation. Method : The separation was crried out on Hypersil ODS column with a mixture o f acetonitrile-1% acetic acid solution (15∶85) as the mobile phase, at a flow rate of 1.0 mL·min -1 . The detection wavelength was set 340 nm. Result: Orientin showed a good linear relationship in the range of 8.42～84.2 μg·mL -1 (r=0.999 9) and the aver age recovery is 98.3%, RSD is 0.8%. Vitexin showed a good linear relationship in the range of 8.07 ～80.7 μg·mL -1 (r=0.999 9) and the average recovery is 102.4%. RSD is 1.7%. Conclusion: The method is sensitive, specific, and accurate with a good repeatability and can be used for the quality control of Trollius chinesis preparation. [更多还原
