Objective To establish a method using HPLC for determination of the content of puerarin and paeonif lorin in compound preparation in the sametime. Method the content of puerarin and paeoniflorin was determented by HPLC at 250nm. 230nm on a C18 column with manthol- acetonitri-0. 05% glacial acetic acid (15: 13: 72) as mobile phase. Results The linear range of calibration curve of puerarin was 5.02?5.3 (r=0. 9998), the average recovery Was 100.82% with RSD of 3.527% (n=5);the linear range of calibration curve...
