| 中文摘要:目的 采用高效液相色谱(HPLC)法测定中药奇蒿中异泽兰黄素和奇蒿黄酮的含量。方法 奇蒿药材以10倍体积甲醇超声60 min提取。色谱分离采用资生堂MG-C18色谱柱(3.0 mm×100 mm,3μm),流动相为乙腈-0.1%甲酸(40:60,V/V),等度洗脱,流速0.5 ml/min,检测波长350 nm,柱温25℃,进样量5μl。结果 异泽兰黄素和奇蒿黄酮在15 min内基线分离,线性良好。方法学验证表明,日内、日间精密度,重复性和稳定性的范围均符合相关标准。异泽兰黄素的低、中、高加样回收率分别为100.26%,99.58%和102.24%;奇蒿黄酮的低、中、高加样回收率分别为99.09%,101.12%和101.43%。结论 该方法快捷简单,稳定可靠,可用于对奇蒿药材进行质量控制。 |

| Abstract:Objective To determine the concentration of eupatilin and arteanoflavone in Artemisia anomala by high performance liquid chromatography(HPLC). Methods Artemisia anomala was extracted by ultrasonic for 60 minutes with 10 times volume of methanol. The HPLC was performed on a SHISEIDO MG-C18 column(3.0 mm×100 mm, 3μm). The mobile phase was a mixture of acetonitrile(ACN) and 0.1% formic acid(40:60, V/V). The detection wavelength was 350 nm, the column temperature was 25℃ and the injection volumn was 5μl. Results Eupatilin and arteanoflavone were separated at baseline within 15min with good linearity. The method validation results show that the precisions, repeatability and stability were all in the normal range. The low,medium and high level recoveries of eupatilin were 100.26%,99.58%,102.24%,and those of arteanoflavone were 99.09%,101.12%,101.43%,respectively. Conclusion The method was rapid, simple, reproductive and accurate. It can be used to control the quality of Artemisia anomala. |
