摘要
采用浸泡与回流的方法从银杏根中提取黄酮 ,用 72 1型分光光度计测得总黄酮含量为 6 .89% .高效液相色谱法检测银杏根中槲皮素百分率为 1.2 4 % ,是黄酮类化合物中含量较高的成分 .紫外 -可见分光光度法确定最佳检测波长为370nm .
Flavonoids was extracted from the foot of the ginkgoes by the method of soaking and backwater.The content of flavonoids determined with a spectrophoto meter of model 721 was 6.89%.In the root of ginkgoes,the content of quercetin accounted 1.24%.It was determined by high performance liquid chromatography.The optimal detection wave length settled by ultiaviolet and visible spectrophoto metry.
