title: [Chemical constituents from stems of Ilex pubescens].
abstract: OBJECTIVE
  To study the chemical constituents from the stems of Ilex pubescens Hook. et Am.
  
  
  METHODS
  The chemical constituents were isolated and purified by various column chromatographic methods with diatomite, silica gel, ODS and Sephadex LH-20. Their structures were identified on physical properties and spectroscopic methods.
  
  
  RESULTS
  Nine compounds were isolated and determined as luteolin(1), quercetin(2), hyperoside(3), rutin(4), 1, 5-dihydroxy-3-methyl-anthraquinone(5),3,5-dimethoxy-4-hydroxy-benzoic acid-1-O-beta-D-glucoside(6), hexadecanoic acid(7), stearic acid(8), n-tetratriacontanol(9), respectively.
  
  
  CONCLUSIONS
  All the compounds are isolated from this plant for the first time, and compounds 5 and 6 are isolated from this genus for the first time.
