title: [Glucosides from Pleurospermum rivulorum].
abstract: OBJECTIVE
  To study the chemical constituents of Pleurospermum rivulorum.
  
  
  METHODS
  To separate the constituents of P. rivulorum by using various kinds of chromatography and identify their structures on the basis of spectral analysis.
  
  
  RESULTS
  Four glucosides were isolated from P. rivulorum. Their structures were established as marmesinin (I), tert-O-beta-D-glucopyranosyl-heraclenol (II), 1'-O-beta-D-glucopyranosyl (2R, 3S)-3-hydroxynodakenetin (III) and 8-hydroxy-5-O-beta-D-glucopyranosyl-psoralen (IV) based on the analysis of spectral data of IR, UV, MS, 1D and 2D-NMR.
  
  
  CONCLUSIONS
  Compounds III and IV are new compounds. All of the four compounds were isolated from this plant for the first time.
