title: [Studies on the chemical components of Clematis chinensis].
abstract: OBJECTIVE
  To study the chemical components of the root of Clematis chinensis.
  
  
  METHODS
  Various chromatographic techniques were used to separate and purify the components. Their structures were determined on the basis of spectral and chemical evidence.
  
  
  RESULTS
  Two compounds were isolated and elucidated as: clemaphenol A (I) and dihydro-4-hydroxy-5-hyroxymethy-2(3H)- furanone (II).
  
  
  CONCLUSIONS
  Compound I and II are new compounds.
