title: [Studies on the chemical constituents from herb of Rhodobryum roseum].
abstract: OBJECTIVE
  To study the chemical constituents from herb of Rhodobryum roseum.
  
  
  METHODS
  The compounds were isolated by column chromatography, and identified by IR, NMR data.
  
  
  RESULTS
  8 compounds were isolated and identified. They are piperine (1), caffeic acid methyl ester (2), uracil glucoside (3), ursolic acid (4), 5alpha, 8alpha-epidioxy-methylcholesta-6, 22-dien-3beta-ol (5), 5alpha, 8alpha-epidioxy-methylcholesta-6,9(11), 22-trien-3beta-ol (6), beta-sitosterol (7), daucosterol (8).
  
  
  CONCLUSIONS
  7 compounds (1-6,8) were isolated from this plant for the first time.
