Objective To establish a method for the determination of hyperoside ,quercetin in Hypericum perforatum by HPLC . Methods The chromatographic conditions were as follows :Hypersil CN (150 mm × 4 .6 mm ,5 μm) column;a mobile phase of methanol‐4 mL · L -1 phosphate (30/70) ,a flow rate of 1 mL · L -1 ;the detection wavelength 241 ,360 nm ;the column tempera‐ture 30 ℃ ;the sample size 20μL .Results Hyperin and quercetin ,with in the concentration of 0 .02‐10 and 0 .03‐8μg · mL -1 re‐spectively showed a good linear relationship .Recoveries were 98 .0% and 98 .1% respectively .Conclusion The method has high specificity ,sensitivity ,and good reproducibility ,and can be used as a method for quercetin and hyperoside determination .
