Objective: To establish HPLC method for simultaneous determination of chlorogenic acid
rutin
isoquercetin and astragalin quercetin in Mori Folium. Method: A HPLC equipped with a Thermo ODS(4.6 mm×250 mm
5μm) column and UV detection was used. The column temperature was at 35℃ and the flow rate 1.0 mL·min-1. The mobile phase was consisited of phosphoric acid in acetonitrile (0.1%
A) and phosphoric acid(0.16%) and triethylamine (0.18%) in water(B) with gradient elution. The detection wavelength was set at 360 nm. Result: The good saperation of five flavo noids was achieved within 60 min. Linear calibration curves were obtained with 0.32-13.73 μg (r=0.999 6)
0.05-3.13 μg(r=0.999 8)
0.03-9.50 μg(r=0.999 4)
0.03-5.60 μg (r=0.999 5)
0.001-0.05 μg (r=0.999 7);the average recovery was 99.61%-106.09%
RSD≤2.8%. Conclusion: The proposed method is simple
accurate
repeatable
and can be used for quality control as well as a powerful tool to evaluate the processing of Mori Folium.
