Objective:To establish the HPLC method for determination of icariin in Gushen pills.Method:HPLC was performed on a Diamonsil C18column (4.6×200 mm
5μm) with acetonitrile-water(20∶80) as mobile phase.Detecting wavelength was 270nm and flow rate was 1.0mL/min.Result:A good linear relationship between peak area and concentration was noted at 0.15~2.10 μg with a correlation coefficient of r=0.99998(n=6) for icariin.The recovery rate of icariin was 97.4%(RSD=2.17%).Conclusion:This method is accurate
repeatable and effective for quality control of Gushen pills.
