OBJECTIVE To establish a method for determination of puerarin in Wuweianshen granules containing puerariae radix.METHOD RP-HPLC,ODS column,methanol:H20(35:65) containing0.01%acetic acid as mobile phase at a flow-rat of 1.2 mL ? min ~,and detected at 252 nm.RESULTS Puerarin was eluted within 5 min without interference with co-existing components,the detection limits was 0.01 μg- 0.32μg(r = 0.9999),the average recovery was 97.3%with RSD = 1.58%.CONCLUSION This method is simple and accurat...
