title: [Chemical constituents of Pileostegia viburnoides var. glabrescens].
abstract: OBJECTIVE
  To study the chemical constituents of Pileostegia viburnoides var. glabrescens.
  
  
  METHODS
  The compounds were isolated and purified by various techniques. Their structures were determined by physicochemical properties and spectral analysis.
  
  
  RESULTS
  Five compounds were isolated and identified as friedelin (1), beta-sitosterol (2), umbelliferone (3), daucosterol (4) and skimmin (5).
  
  
  CONCLUSIONS
  All the compounds were isolated from this genus for the first time.
