title: [Steroids from Monascus purpureus metabolite].
abstract: OBJECTIVE
  To study the chemical constituents of Monascus purpureus metabolite.
  
  
  METHODS
  The compounds were isolated by column chromatography methods, and their structures were determined by spectroscopic methods.
  
  
  RESULTS
  Eight compounds were isolated from the petroleum ether fraction of ethanolic extract and elucidated as stigmast-4-en-3-one (1), 3-oxo-24-methylenecycloarane (2), stigmasterol (3), 7beta-hydroxystigmasterol (4), 3beta-hydroxystigmast-5-en-7-one (5), 3beta-hydroxystigmast-5,22-dien-7-one (6), 5alpha, 8alpha-epidioxyergosta-6,22-dien-3beta-ol (7), sitosterol (8).
  
  
  CONCLUSIONS
  All of the compounds were isolated from this genu for the first time except compound 3 and 7.
