精制冠心颗粒复方中4味药材HPLC指纹图谱研究

    Study on HPLC Fingerprint of Four Kinds of Drugs of Jingzhi Guanxin Keli Fufang

    • 摘要: 目的 利用HPLC建立精制冠心颗粒复方中4味药材指纹图谱。 方法 运用Agilent 1100 DAD-HPLC高效液相色谱仪,采用Inertsil ODS-3(4.6 mm×250 mm,5 μm)色谱柱,乙腈-0.1%磷酸梯度洗脱,流速1.0 mL·min-1,检测波长270 nm,柱温30 ℃,进样量:10 μL,对精制冠心颗粒复方四味药材进行试验。 结果 10批精制冠心颗粒复方中4味药材中共获得22个共有峰,不同批次样品相似度均>0.90,方法精密度、稳定性和重复性良好。 结论 采用HPLC建立的精制冠心颗粒复方中4味药材指纹图谱,方法稳定、可靠、简便,色谱图展现的各峰分离度较好,特征明显,可做为精制冠心颗粒复方真伪鉴别标准。

       

      Abstract: OBJECTIVE To establish the chromatographic fingerprint of Jingzhi Guanxin Keli Fufang by HPLC. METHODS HPLC was performed on Jingzhi Guanxin Keli Fufang using Agilent 1100 DAD-HPLC. Inertsil ODS-3 column (4.6 mm×250 mm, 5 μm) was used; the mobile phase was acetonitrile-0.1% phosphoric acid for gradient elution; the flow rate was 1 mL·min-1; the detection wavelength was 270 nm; the column temperature was 30 ℃, and inject volume was 10 μL. RESULTS Twenty-two HPLC common peaks were acquired in the 10 batches of four kinds of drugs of Jingzhi Guanxin Keli Fufang, and their similarities were >0.90. Good precision, stability and repetition were showed. CONCLUSION A reliable method is provided for the quality identification of Jingzhi Guanxin Keli Fufang. And the chemical components of different germplasms of Jingzhi Guanxin Keli Fufang are different from each other; selection of germplasm is important in quality control of Jingzhi Guanxin Keli Fufang.
