摘要:

建立了反相高效液相色谱-二极管阵列检测法同时测定毛冬青根中的6种活性成分 (tortoside A, (+)-丁香脂素, 毛冬青皂苷B3, 毛冬青皂苷A1, 毛冬青皂苷B1, 毛冬青素A) 的含量。RP-HPLC分离用反相C18分析柱, 流动相以乙腈-0.1%磷酸水体系梯度洗脱。流速1.0 mL/min, 检测波长为210 nm6个指标成分达到基线分离, 标准曲线具有良好的线性 (r2>0.9996), 精密度、稳定性和重复性符合分析方法学要求。加样回收率范围为99.00%-104.52%。最后对15个批次的毛冬青药材含量测定结果进行了聚类分析。结果表明该方法不仅可以对毛冬青药材进行质量控制, 而且也为毛冬青药材的道地性分析提供了科学依据。

Abstract:

A reversed-phase high performance liquid chromatography (RP-HPLC) method with diode array detector (DAD) has been established to simultaneously determine six bioactive compounds in the roots of Ilex pubescens, namely tortoside A, (+)-syringaresinol, ilexsaponin B3, ilexsaponin A1, ilexsaponin B1, ilexgenin A. The RP-HPLC assay was performed on a reversed-phase C18 column with a gradient elution. The mobile phase consisted of acetonitrile and water containing 0.1% (v/v) phosphoric acid. The flow rate was 1.0 mL/min and the detection wavelength was set at 210 nm. The six marker constituents were separated well with good linearity (r2>0.9996), precision, stability and repeatability. The overall recoveries were in the range of 99.00%–104.52%. Cluster analysis was employed to analyze 15 batches of samples. The result indicated this method provide an efficient way to perform quality control as well as a scientific rationale for the Geo-authentication of I. pubescens.
