| 中文摘要:目的 建立HPLC法测定不同采收期的罗布麻叶和其商品药材中槲皮素的含量。方法 采用Aglient Eclipse XDB-C18色谱柱（250 mm×4.6 mm，5 μm），流动相：甲醇-0.1%磷酸，梯度洗脱，检测波长：360 nm，柱温：30℃。结论 罗布麻由开花转向结果和叶由绿变黄时，槲皮素的含量相对较高，是采集叶较理想的时间。国内部分省市销售的大多数罗布麻叶药材中的槲皮素含量符合药典规定，也尚有少数样品未达到药典标准，建议有关部门还需加强对罗布麻叶的质量监督检查。 |

| Abstract:Objective To determine the quercetin content in Folium Apocyni Veneti from different commercial markets and harvest time by HPLC.Methods The determination was performed on an Aglient Eclipse XDB-C18 column (250 mm×4.6 mm,5 μm)at 30℃ with a mobile phase composed of Methanol:0.1% phosphoric acid run at gradient elution; the detection wavelength was 360 nm.Results It is a better timing to harvest when the flower is turning fruit and the leaf color is turning from green to yellow. Our results have demonstrated that at that time, the content of quercetin in Folium Apocyni Veneti was relatively higher. In addition, this report also shows that the concentration of quercetin in most medicinal materials from domestic market complies with the requirement of the Pharmacopoeia, but there were still a small percent of samples that didn't meet the Pharmacopoeia standards.Conclusion We suggested that the quality supervision and inspection on Folium Apocyni Veneti needs to be strengthened. |
