To establish a simple and reliable method for rapid separation and identification of chemical components in Polygonum multiflorum Formula Granules.An ultra-performance liquid chromatography tandem quadrupole time-of-flight mass spectrometric method( UPLC/Q-TOF MS) was used. The separation was performed on an Agilent Eclipse Plus C18 RRHD(100 mm x 2.1 mm, 1.8 μm) column with a mobile phase of water and acetonitrile in a gradient elution mode. The flow rate was 0.4 mL/min and the column temperature was maintained at 25 degrees C. TOF MS was applied for qualitative analysis under positive ion mode.Five compounds were identified by the time of flight mass spectrometry and literature data.This method is accurate, rapid and sensitive, it can provide reference for the quality control of Polygonum multiflorum Formula Granules. |
