title: New hydrolysable tannin from Cibotium barometz.
abstract: OBJECTIVE
  To study the chemical constituents from Cibotium batometz.
  
  
  METHODS
  Column chromatograph and HPLC were used to isolate and purify the compound, and the structure was elucidated on the basis of MS and NMR spectroscopic methods.
  
  
  RESULTS
  A new phenolic compound, 4-O-caffeoyl-D-glucopyranose, has been isolated from the rhizome of C. barometz. The structure of the new compound was elucidated on the basis of chemical and spectroscopic methods, including intensive 1D, 2D NMR and ESI-MS data analysis.
  
  
  CONCLUSIONS
  4-O-caffeoyl-D-glucopyranose was a new phenolic compound.
