摘要
提出了AlCl3 分光光度法测定药物制剂中银杏黄酮含量的新方法。该法是基于银杏黄酮能与AlCl3反应生成黄色络合物,此物质在408nm处有最大吸收。方法的线性范围为2.00～110μg/mL,r=0.9999,平均回收率为99.9%。
A new method was discussed to determinate flavonoids of Ginkgo biloba in drugs by aluminum chloride spectrophotometry at the wavelength of 408 nm. It based on which flavonoids of Ginkgo biloba could react with aluminum chloride. The linear region was 2.00～110 μg/mL,r=(0.999 9), and the average recovery was 99.9%.
