title: [HPLC-ESI-MS(n) analysis of the water soluble extracts of Fructus Choerospondiatis].
abstract: OBJECTIVE
  To establish an HPLC-ESI-MS(n) method for analyzing the chemical ingredients in the water soluble extracts of Fructus Choerospondiatis.
  
  
  METHODS
  Water-solvable extracts of Fructus Choerospondiatis are obtained by heating recirculation. Multi-stage reaction mode (MRM) of the HPLC-ESI-MS(n) was used to determine the content of Gallic acid, the MS(n) technology was used to obtain the information of characteristic multistage fragment ions so as to identify the chemical structure of peaks in the total current spectrum.
  
  
  RESULTS
  Eleven compounds were identified, and one of them is a new unknown ingredient.
  
  
  CONCLUSIONS
  The method, which has high recovery and specificity, can offer the experimental evidences for the further research of the chemical ingredients extracted from the Fructus Choerospondiatis.
