title: [Studies on chemical constituents from root of Clematis hexapetala].
abstract: OBJECTIVE
  To study the chemical constituents from the roots and rhizomes of Clematis hexapetala.
  
  
  METHODS
  The compounds were separated by means of solvent extraction, repeated chromatography with silica gel and HPLC. The structures were determined by spectral analysis.
  
  
  RESULTS
  Nine compounds were isolated as friedelin (1) , anemonin (2) , beta-sitosterol (3) , palmitic acid (4) , vanillic acid (5) , isolariciresinol (6) , 5-hydroxumethyl-5H-furan-2-one (7) , n-nonane (8) , daucosterol (9).
  
  
  CONCLUSIONS
  All the compounds were isolated from the plant for the first time.
