title: [A new fatty ketone of Radix Polygoni Multiflori Preparata].
abstract: OBJECTIVE
  Investigating the chemical constituents of Radix Polygoni Multiflori Preparata.
  
  
  METHODS
  Compounds were isolated from the CHCl3 extract with column chromatography on silica gel, and identified on the basis of spectral analysis(IR, EI-MS, 1H-NMR, 13C-NMR) and phytochemical properties.
  
  
  RESULTS
  Two compounds were isolated and identified as 1,2-dihydroxynonadecone-3(I) and gallic acid(II).
  
  
  CONCLUSIONS
  Compound I is a new compound.
