| Abstract: | Objective To establish an HPLC method for the determination of quercetin in receptaculum nelumbinis. Methods The separation was performed on Phenomenex- C18 Column（4.6 mm × 250 mm,5 um） with methanol -0.2% phosphoric acid （50：50 ） as mobile phase. The flow rate was 1.0 mL . min -1 , the detection wavelength was 360 nm and the column temperature was 30 ℃. Results The linear range of quercetin was 0. 204 - 2. 040 ug （ r = 0. 999 7 ）, the average recovery was 99.44% and the RSD was 0.82% （ n = 6 ）. Conclusion This method was convenient, rapid and accurate with good reproducibility and stability, and it can be used for the quality control of receptaculum nelumbinis. |
