title: [Studies on chemical constituents in the peels of Citrus changshan-huyou (I)].
abstract: OBJECTIVE
  To reveal the pharmacological activities of the components for their further utilization and development by studying the chemical constituents of Citrus changshan-huyou.
  
  
  METHODS
  The structures were determined by repeated silica gel chromatographic separation and spectral analysis.
  
  
  RESULTS
  Five compounds were obtained, and identified as 3-oxo friedelin (I), limonin (II), beta-sitosterol (III), 8-(2',3'-dihydroxy-4'-methylbutane)-7-methoxycoumarin (IV), sucrose (V).
  
  
  CONCLUSIONS
  The five compounds were obtained from this plant for the first time.
