title: [Chemical constituents of Loxocalyx urticifolius Hemsl].
abstract: OBJECTIVE
  To investigate the chemical constituents from the whole plant of Loxocalyx urticifolius.
  
  
  METHODS
  The chemical constituents were isolated by chromatography and identified by MS, 1H NMR, 13C NMR and 2D-NMR methods.
  
  
  RESULTS
  The structures were established as poliothrysoside, beta-sitosterol and stigmasterol, palmitic acid and tyrosine.
  
  
  CONCLUSIONS
  This is the first time for the chemical constituents of L. urticifolius to be reported.
