title: [Studies on the chemical constituents of ethyl acetate extraction from Reineckea carnea].
abstract: OBJECTIVE
  To study the chemical constituents of Reineckea carnea.
  
  
  METHODS
  The compounds were isolated by extraction, silica gel and reversed phase silica gel column chromatography. The structures were identified by various spectroscopic methods including 1D and 2D-NMR spectrum, MS, IR, etc.
  
  
  RESULTS
  Six compounds were isolated and identified as beta-sitosterol (1), isorhodeasapogenin (2), isorhodeasapogenin (3), (25S)-1beta,3beta,4beta-trihydroxyspirotan-5beta-yl-O-beta-D-glucopyranoside (4), kitigenin-5-O-beta-D-glucopyranoside (5) and nicotianoside B (6).
  
  
  CONCLUSIONS
  Compounds 4, 6 are obtained from this plant for the first time.
