title: [Chemical constituents contained in roots of Pterospermum heterophyllum].
abstract: OBJECTIVE
  To study chemical constituents of contained in roots of Pterospermum heterophyllum.
  
  
  METHODS
  The chemical constituents of P. heterophyllum were separated and purified by silica gel, sephadex LH-20, ODS column chromatography and preparative HPLC. Their structures were identified by spectroscopic techniques.
  
  
  RESULTS
  Ten compounds were separated and identified as asperglaucide (1), 2-methoxy4-hydroxyphenol-1-O-beta-D-apiofuranosyl (1-->6)-O-beta-D-glucopyranoside (2), 5, 5'-dimethoxy-9-beta-D-xylopyranosyl-(-) -isolariciresinol(3), (-)-epicatechin (4), eriodictyol (5), taxifolin (6), 3beta-hydroxy-12-en-28-ursolic acid (7), 2beta, 3beta-dihydroxy-12-en-28-oleanolic acid (8), quercetin (9), cholest-4-en-3-one (10).
  
  
  CONCLUSIONS
  Compounds 1-10 were separated from this plant for the first time.
