title: [Studies on chemical constituents in roots of Rumex dentatus].
abstract: OBJECTIVE
  To investigate the active constituents from Rumex dentatus.
  
  
  METHODS
  Compounds were isolated by silica gel, Sephadex LH -20 and ODS column chromatography and identified by chemical and spectroscopic methods.
  
  
  RESULTS
  Ten compounds were obtained and identified as helonioside A (1), gallic acid (2), isovanillic acid (3), p-hydroxycinnamic acid (4), succinic acid (5), n-butyl-beta-D-fructopyranoside (6), quercetin (7), hexadecanoic acid 2, 3-dihydroxy propyl ester (8), beta-sitosterol (9) and daucosterol (10).
  
  
  CONCLUSIONS
  Compounds 1, 3-6 and 8 were isolated from the genus of Rumex for the first time.
