title: [The chemical constituents of Breynia rostrata].
abstract: OBJECTIVE
  To study the chemical constituents of Breynia rostrata Merr.
  
  
  METHODS
  Chromatography was used to isolate and purify the chemical constituents, their structures were identified by spectral analysis.
  
  
  RESULTS
  Four glycosides were identified as 6-O-methylpropanoyl-alpha-D-glucopyranoside (1), 4"-phenolic-6-O-methylpropanoyl-beta-D-glucopyranoside (2), 1-O-galloyl-beta-D-glucopyranoside (3), arbutin (4).
  
  
  CONCLUSIONS
  Compounds 1 and 2 are new compounds; 3 and 4 were isolated from Breynia rostrata Merr. for the first time.
