中药苏叶与苏梗中黄酮含量测定

Determination on Flavone Content in Traditional Chinese Medicine Folium Perillae and Caulis Perllae

[目的]建立苏叶和苏梗中黄酮含量测定的紫外分光光度法。[方法]以芦丁为对照品,采用紫外分光光度法在510 nm处分别测定苏叶和苏梗中的总黄酮含量。[结果]苏叶、苏梗中总黄酮的含量分别为57.174 3、3.850 2 mg/g,总黄酮提取率分别为5.72%、0.39%,苏叶中总黄酮含量远高于苏梗中总黄酮含量。[结论]对于研究紫苏中黄酮类化合物,苏叶更具有研究价值。

[Objective] The aim was to establish ultraviolet spectrophotometry for determining flavone content in folium perillae and caulis perllae. [Method] With rutin as control,flavone content in folium perillae and caulis perllae was determined at 510 nm by ultraviolet spectrophotometry. [Result]Total flavone in folium perillae and caulis perllae were 57. 174 3,3. 850 2 mg / g,extraction rate were 5. 72%,0. 39%,total flavone content in folium perillae was higher than that in caulis perllae. [Conclusion] Folium perillae has more research value in research about flavonoid.
