    Abstract：ObjectiveTo study the optimum extracting condition of total flavonoids in Flos Pyrethri Tatsienensis. MethodsUsing Rutin as the evaluating criteria, the extraction condition was studied by ultraviolet spectrophotometry. ResultsThe optimum extracting condition was as follows：50% ethanol,solidliquid ratio 1∶50 and refluxing and extracting for 3 h at 100℃. ConclusionThe optimum extracting condition was B3C3A2D3.
