Abstract: Objective To establish an HPLC method for the determination of Tectoridin and Tectorigenin in Flos Puerariae lobata. Method The separation was performed on Agilent -C18 column(4.6 mm×250 mm,5 μm),using a mobile phase with methanol-acetonitrile-water(2∶1∶2). Flow rate was 1.0ml/min,the detection wavelength was set at 264 nm. Column temperature was ambient temperature. Result The linear range of tectoridin was 2.0 ~120.0 μg/ml,r=0.999 8.The average recovery was 99.7%,RSD was 1.9%;The linear range of tectorigenin was 0.8 ~80.0 μg/ml,r=0.998 6.The average recovery was 99.4%,RSD was 1.7%. Conclusion The method was simple ,accurate,reliable with a good repeatability,which could be used to determinate of tectoridin and tectorigenin in Flos Puerariae lobata.
