Abstract

AIM:This paper described a HPLC method.Paeoniflorin and puerarin in Rg soft-exact(Radix Puerariae lobatae,Redix Paeoniae alba,etc.) were simultaneously determined.METHODS:A simplified HPLC procedure was developed.A 4.6 mm×250 mm Alltima C_(18) column with a mobile phase consisting of NaH_2PO_4(20 Mm,pH 2.4)-Acetonitrile:Tetrahydrofuran(900:120:5) was used.The flow rate was 1.00 mL/min.It was detected at 320 nm.RESULTS:Paeoniflorin and puerarin were well separated.The average recoveries of paeoniflorin and puerarin were 98.10% and 101.2% respectively.CONCLUSION:The result shows that this method is convenient,rapid and accurate.
