title: [Studies on chemical constituents from roots of Cudrania cochinchinensis].
abstract: OBJECTIVE
  To study the chemical constituents from the roots of Cudrania cochinchinensis.
  
  
  METHODS
  The chemical constituents of C. cochinchinensis were isolated and purified by silica gel, polyamide column chromatography, Their structures were identified on the basis of spectroscopic data.
  
  
  RESULTS
  Six compounds were isolated and identified. Their structures were established as 3, 5, 7, 4"-tetrahydroxyflavanone-7-O-(6"-acetyl)-glucoside (1), 3, 5, 7, 4'-tetra hydroxyflavanone-7-O-glucoside (2), 2', 4', 5, 7-tetrahydroxy-6-prenyldihydroflavanone (3), 5, 7, 4'-trihysdroxy-6-prenylisoflavanone (4), 1, 3, 5, 6-tetrahydroxyxanthone (5), stilbene-2, 4, 3', 5'-tetraol (6).
  
  
  CONCLUSIONS
  Compound 1 was isolated from this genus, while compounds 4 and 5 were isolated from this plant for the first time.
