    摘要:

    目的:建立护肝颗粒中槲皮素、山柰素、异鼠李素的含量测定方法。方法:采用高效液相色谱法测定护肝颗粒中槲皮素、山柰素、异鼠李素的含量,色谱柱Hedera ODS-2柱(4.6 mm×200 mm,5 μm),流动相为甲醇-0.4%磷酸,梯度洗脱,流速1 mL/min,检测波长360 nm,柱温为35 ℃。结果:槲皮素、山柰素、异鼠李素分别在0.0768~1.92 μg,0.02004~0.501 μg,0.021~0.525 μg范围内进样量与峰面积积分值线性关系良好,r分别为0.9999、0.9998、0.9999,加样回收率分别为97.4%、98.1%、97.9%,RSD分别为1.4%、1.8%、1.3%。结论:该方法准确、稳定,可以用来同时测定护肝颗粒中槲皮素、山柰素、异鼠李素的含量。

    Abstract:

    To develop method for detetmining uercetin,Kaempferide and Isorha-mnetin in Hugan granules by HPLC.Methods:HPLC was used for the determination of uercetin,Kaempferide and Isorha-mnetin.The column was set as Hedera ODS-2 (4.6 mm×200 mm,5 μm).The mobile phase was methanol-0.4% phosphoric acid,and the gradient elution was used.The detection wavelength was set at 360 nm and the flow rate was 1.0 mL·min.Results:uercetin,Kaempferide and Isorha-mnetin showed a good linear relationship in the range of 0.0768~1.92 μg(r=0.9999),0.02004~0.501 μg(r=0.9998) and 0.021~0.525 μg (r=0.9999).The average recovery of uercetin was 98.1% with RSD of 1.4%,the average recovery of Kaempferide was 98.1 % with RSD of 1.8%,and the average recovery of Isorha-mnetin was 97.9 % with RSD of 1.3%.Conclusion:The method is accurate and stable,which can be used for the determination of uercetin,Kaempferide and Isorha-mnetin in Hugan granules.
