摘要:

了反相高效液相色谱法同时测定扁蓄药材中8个黄酮 (杨梅苷, 金丝桃苷, 木犀草苷, 扁蓄苷, 槲皮苷, 槲皮, 木犀草素和山奈酚)的含量。采用Inertsil ODS-4 色谱柱, 乙腈0.5%磷酸水溶液梯度洗脱, 流速为1 mL/min, 温为35 ºC,检测波长为360 nm。上述8个黄酮类成分达到基线分离, 标准曲线线性关系良好 (r2>0.9991), 日内和日间精密度、稳定和重复性实验均符合要求, 加样回收率为95.58%102.65%。对28批不同产地的扁蓄样品进行了含量测定和聚类分析,结果表明该方法不仅可以对萹蓄药材进行质量控制, 对于萹蓄药材的道地性分析也提供了科学数据。

Abstract:

A reliable high performance liquid chromatography method was developed for the quality evaluation of Polygonum aviculare L. Eight marker flavonoids were identified and simultaneously quantified, which included myricitrin, hyperoside, galuteolin, avicularin, quercitrin, quercetin, luteolin, and kaempferol. The analysis was performed on an Inertsil ODS-4 column (4.6 mm×150 mm, 5 µm) with gradient elution. The mobile phases were 0.5% aqueous phosphoric acid and acetonitrile. The detection wavelength was 360 nm. The eight marker flavonoids were separated well with good linearity (r2>0.9991), precision, stability and repeatability. The recovery rate was 95.58%102.65%. Cluster analysis was employed to analyze 28 batches of samples. The result indicated that this method provides an efficient way to perform quality control as well as a scientific rationale for the Geo-authentication of Polygonum aviculare L.
