Determination of Quercetin in Semen Hoveniae by RP-HPLC / 中药新药与临床药理

ABSTRACT

Objective To determine the content of quercetin in Semen Hoveniae.Methods A RP-HPLC method was established.The chromatographic column was Synergi 4u Fusion-RP 80.The mobile phase was acetonitrile-0.5 %phosphoric acid(33 ∶67).The flow rate was 1.0 mL?min-1,the detection wavelength was at 360 nm,and the column temperature was 30 ℃.Results The average recovery of quercetin was 98.6 %,and RSD was 2.39 %(n=6).Conclusion The method is effective,simple and accurate,and can be used to determine the content of quercetin in Semen Hoveniae.
