Abstract:
Objective To study the quality standard of Folium Nelumbinis.Methods Flavonoids of Folium Nelumbinis were identified by TLC.The extraction conditions of flavonoids was studied and the content of total flavonoids was determined by ultraviolet spectrophotometry .Results Quercetin in Folium Nelumbinis was identified by TLC.The optimal extraction conditions were defined and the content of total flavonoids was about 13 %.Conclusion This method is simple and convenient, and is feasible for the quantitative determination of Folium Nelumbinis.
