摘要
目的建立同时测定杞蓉片中淫羊藿苷和金丝桃苷含量的方法。方法采用HPLC法。色谱柱为Diamonsil ODS柱(4.6mm×200mm,5μm),流动相为乙腈-体积分数为0.1%磷酸-四氢呋喃(体积比20:80:12),流速为1.0mL·min^-1,检测波长270nm,柱温30℃。结果淫羊藿苷质量浓度在2.5—25.0mg·L^-1内、金丝桃苷质量浓度在2.0~20.0mg·L^-1内与峰面积呈良好的线性关系,相关系数分别为0.9998和0.9995;平均回收率分别为100.8%(RSD=1.4%)和97.9%(RSD=1.1%)。结论本方法简便、快捷,结果准确,重复性好,可作为杞蓉片的质量控制方法之一。
Objective To establish an HPLC method for simultaneous determination of icariin and hyperoside in Qirong( traditional Chinese medicine)tablets. Methods The chromatographic method was carried out on a Diamonsil C18 column ( 200 mm ×4.6 mm, 5 μm ) with acetonitrile-0. 1% phosphoric acid-tetrahydrofuran (V: V: V=20:80: 12)as the mobile phase. The flow rate was 1.0 mL.min^-1 and column temperature was 30 ℃. The detection was set at the wavelength of 270 nm. Results The calibration curve was linear within the range of 2. 5 - 25.0 mg. L^-1 ( r = 0. 999 8 ) for icariin and 2. 0 - 20. 0 mg.L^- 1 ( r = 0. 999 5 ) for hypero- side,the average recoveries were 100. 8% (RSD = 1.4% )for icariin and 97.9% (RSD = 1.1% )for hyperoside. Conclusions The method is simple, accurate and reproducible, which can be used for the quality control of Qirong tablets.
