Objective:To establish the method for determination of quercetin in Crneate Lespedeza .Methods :The content of quercetin was determined by HPLC .The column was Agilent HC‐C18 column (150mm × 4 .6mm ,5μm) . The mobile phase was Methanol and 0 .3% phosphoric acid solution (55∶45) .The detection wavelength was 370 nm . The flow rate was 1 mL · min‐1 .Results :Linearity range of quercetin was 1 .84μg · mL‐1 ~18 .4μg · mL‐1 (r=0 .9992) . The average recovery was 97 .7% and RSD was 1 .99% .Conclusion :The methods are proved to be simple ,accurate and reproducible .It can effectively control the quality of Crneate Lespedeza .
