title: [Chemical constituents from Salix oritrepha Schneid].
abstract: OBJECTIVE
  To study chemical constituents of the above ground part of Salix oritrepha.
  
  
  METHODS
  Using chromatography to isolate compounds and their structure were identified by physical, chemical and spectral techniques.
  
  
  RESULTS
  Four compounds were isolated and elucidated as beta-sitosterol, beta-sitosteryl-3-O-glucoside, friedelin, luteolin-7-O-glucoside.
  
  
  CONCLUSIONS
  All of them were isolated from S. oritrepha for the first time. Friedelin from the plants of genus Salix for the first time.
