title: [Studies on chemical constituents from roots of Caragana microphylla].
abstract: OBJECTIVE
  To study the chemical constituents in roots of Caragana microphylla.
  
  
  METHODS
  The constituents were isolated by silica gel column chromatography, and their structures were identified by spectroscopic methods and chemical evidence.
  
  
  RESULTS
  Eight compounds were identified as beta-sitosterol (1), pseudobaptigenin (2), pentacosanylferulates (3), heptadecanylferulates (4), ferulic acid (5), daucosterol (6), trifolirhizin (7), ononin (8) respectively.
  
  
  CONCLUSIONS
  Compounds 1, 3-7 were obtained from the plant for the first time, and 3, 4, 5 and 7 were obtained from the genus Caragana for the first time.
