Abstract:
Objective To establish an HPLC method for testing the content of icariin in Yinyangsu capsules.Methods An Lichrospher C18(4.6mm?250mm,5?m) was used as the column,and column C18 as the protecting column.The mobile phase was a mixture of acetonitrile-20g/L acetum(30∶70) in a flow rate of 1.0mL/min.The detected wavelength was 270nm.Column temperature was room temperature and the injection quantity was 10?L.The sample was prepared when we added 50%(V/V) alcohol and then made ultrasonic extraction.Measurement was made after the prepared sample was filtrated on 0.45?m filter paper.Results Icariin in the sample was well separated.The linear range was 10.0-60.0mg/L.The linear equation was C=2.042?10-5A+0.554,while the correlation coefficient was 0.9993;the average recovery was 99.8% and RSD was 0.65%(n=6).Conclusion This method can be used in content measurement of Yinyangsu capsules.
