Objective To establish a method for simultaneous determination of icariin and naringin content in bushen huayu extract by HPLC. Methods Reverse-phase high performance liquid chromatography ( RP-HPLC ) separation was performed one C18 column (4.6 mmí250 mm,5 μm).The mobile phase was acetonitrile containing 0.2%H4PO3(pH=2.9). Gradient elution with a flow rate of 0. 8 mL·min-1 was applied to achieve the separation. The detection wavelength was set at 269 nm,and the column temperature was 30℃. Results Icariin had a good linear range from 0. 3-3. 0μg (r=0. 999 9),the recovery rate was 105. 6%,and RSD was 0. 95%. Naringin was linear within the range of 0. 12-1. 20 μg (r=0. 999 9). The recovery rate was 94. 0%and RSD was 0. 52%. Conclusion The method is simple,stable,accurate,and reproducible,which can be used as the quality control standard for bushen huayue extract.
