| Abstract: | Objective ： To establish a methods for determination of icariin in qiyang capsules by HPLC. Method ： The Kromasil C18 column （ 250 mm × 4. 6 mm,5μm） was used. The mobile phase was methanol-water-acetic acid （45 ： 50：5 ） with 1.0 ml- min - 1 of flow rate at ambient temperature. The detection wavelength was at 270 nm. Result： The linear range of ieariin was 0. 047 9-0. 958 0 μg. ml- 1 （ r = 0. 999 9） . The average recovery was 99. 14% and RSD was 0. 51% （ n = 6） . Conclusion： The method is simple and quick for determination of this preparations. |
