Abstract: |
Objective:To establish a method for content determination of anemonin in Ranunculus japonicus Thunb.Methods:High-performance liquid chromatography was performed on a Merck Hibar C18 column (4.6mm×250mm,5μm) with a mobile phase of methanol-water (30∶70) at a detection wavelength of 220nm,a flow rate of 0.8ml/min,a column temperature of 30℃,and a sample size of 20μL.The number of theoretical plates for anemonin was ≥4000.Results:Anemonin showed a good linear relationship within the range of 0.342~8.108mg/ml,with an average recovery rate of 98.7% (n=9) (relative standard deviation=1.2%).Conclusion:This method is simple and accurate with reliable results and can be used as an effective method for the content determination of anemonin in Ranunculus japonicus Thunb. |
