title: [Studies on chemical constituents in root of Rumex patientia L].
abstract: OBJECTIVE
  Investigating the chemical constituents in the root of Rumex patientia.
  
  
  METHODS
  Compounds were separated by rechromatography on silica gel. Their structures were determined by spectral analysis and chemical evidence.
  
  
  RESULTS
  Eight compounds were isolated and identified as 5-methoxy-7-hydroxy-1 (3H)-benzofuranone (I), 5, 7-dihydroxy-1 (3H)-benzofuranone(II), nonadecanoic acid-2,3-dihydroxypropyl ester(III), torachrysone-8-O-beta-D-glucopyranoside(IV), gallic acid(V), beta-sitosterol(VI), beta-sitosterol-3-O-beta-D-glucopyranoside(VII) and catechin(VIII).
  
  
  CONCLUSIONS
  Compound III is a new natural products, and compounds I and II were obtained from this plant for the first time.
