OBJECTIVE To establish the method for determining the content of icariin in Baji Capsule.METHOD HPLC method was adopted,with Lichrospher C_(18) chromatographic column(4.6 mm × 200 mm,5μm),methanol-1% ethanoic acid(51∶49) as the mobile phase,flow rate at 1.0 mL/min,column temperature at 30℃,and detection wavelength at 270 nm.RESULT Linear range: 0.06425~1.028 μg;r=1.000;detection limit: 0.2 ng,sample recovery rate: 100.32%;RSD=0.60%(n=6).CONCLUSION This method is simple,practical and stable with good reprodu...
