摘要
采用反相高效液相色谱法分离银杏叶提取物中黄酮类化合物并测定其中槲皮素含量。YWGC18(046cm×15cm)色谱柱,流动相甲醇水磷酸(50∶498∶02),检测波长360nm。回收率在953%~1032%之间,RSD为186%。
This paper reports the HPLC determination of one of the flavones quercetin in the extract of Ginkgo biloba leaves.Quercetin was separated completely on an YWG C 18 column(0.46cm×15cm),using a mixture of methanol,water and phosphoric acid(50∶49.8∶0.2) as mobile phase,with UV detection at 360nm.The results have shown the recoveries to be between 95.3%~103.2% and RSD 1.86%.
