title: [Study on the chemical constituents of mori cortex].
abstract: OBJECTIVE
  To study the chemical constituents of Mori Cortex.
  
  
  METHODS
  The compounds from the dichloromethane-methanol extracts were isolated by the silica gel column chromatography, and their structures were identified by the spectral analysis and chemical evidence.
  
  
  RESULTS
  Eight compounds were obtained and their structures were identified as 3-acetyl-beta-amyranol (1), neotocopherol (2), alpha-amyrin (3), clionasterol (4), betulinic acid (5), moracin O (6), morusin (7) and morusignin L (8).
  
  
  CONCLUSIONS
  Componds 2 and 4 are obtained from this plant for the first time.
