Research on Cleaning Mechanism of Epimedium wushanense

Objective:To study the cleaning scientificalness of Epimedium wushanense.Method:UV-spectrophotometry was used to determine the content of total flavonoids;HPLC was used to determine the content of three kinds of flavonoids namely epimedin C,icariin,icarisideⅡ.Result:The content of total flavonoids in leaf blades,leaf stalks,leaves of E.wushanense was 9.185%,2.143%,3.364% respectively;the content of epimedin C was 5.346%,0.653%,1.577% respectively;the content of icariin was 1.430%,0.047%,0.321% respectively;the content of icarisideⅡ was 0.328%,0.077%,0.078% respectively.Conclusion:The chemical compositions of flavonoids of leaf blades,leaf stalks,leaves have no obvious difference,but the content of them is different.The content of total flavonoids of leaf blades is more than 4 times that of leaf stalks.It has scientific value to remove the leaf stalks.
