| Abstract:Objective To identify the chemical components in Artemisiae argyi folium by rapid resolution liquid chromatography-time of flight mass spectrometry (RRLC-TOFMS).Methods The separation was performed on an Agilent Eclipse C18 column (2.1 mmü100 mm,1.8 μm ). The mobile phase consisted of acetonitrile (A) and 0.1% formic acid (B) were in gradient elution.The flowing rate was 0.35 ml/min, the injection volume was 1 μl and the temperature of column was 40℃. Time of flight mass spectrometer (TOFMS) with electro spray ion source (ESI) was applied to qualitative analysis under the positive ion mode,and mass scan range was m/z 100-1 500.Results 31 chemical compounds in Artemisiae argyi folium were identified unequivocally.Conclusion A rapid and efficient RRLC-TOFMS approach for identifying the chemical constituents of Artemisiae argyi folium had been successfully established,which paved a way for quality control and further in vivo studies of Artemisiae argyi folium. |
