title: [Water-soluble non-alkaloid chemical constituents contained in Corydalis yanhusuo by trimethylsilyl derivatization GC-MS].
abstract: OBJECTIVE
  To study the water-soluble non-alkaloid chemical constituents of Corydalis yanhusuo.
  
  
  METHODS
  The 80% alcohol extracts of C. yanhusuo passed through DA201 macroporous resin. Eluted fractions were collected and passed though 732 # cation exchange resin. Water eluate was collected, dried and derived with trimethylsilane. Gas Chromatography/Mass Spectrometry and NIST 2005 library were adopted for MS/MS mass spectrogram to infer the compound structure.
  
  
  RESULTS
  Sixteen compounds were tentatively identified from about fifty peaks detected by GC-MS and identified as hydroxyl and carboxyl polar compounds.
  
  
  CONCLUSIONS
  These sixteen compounds were found for the first time in C. yanhusuo. The results provide scientific basis for in-depth development of C. yanhusuo.
