title: [Studies on chemical constituents in the mycelia from fermented culture of Flammulina velutipes].
abstract: OBJECTIVE
  To study the chemical constituents from the mycelia of Flammulina velutipes.
  
  
  METHODS
  The compounds were isolated with silica gel column chromatography and their structures were elucidated on the basis of chemical evidences and spectral analysis (IR, EI-MS, 1H-NMR, 13C-NMR).
  
  
  RESULTS
  Five compounds were identified as 5alpha,8alpha-epidioxy-(22E,24R)-ergost-6,22-dien-3beta-ol (1), ergosta-4,6,8(14),22-tetraen-3-one (2), sterpuric acid (3), mannitol (4), ribitol (5).
  
  
  CONCLUSIONS
  The compounds (2)-(5) were isolated for the first time from the mycelia of Flammulina velutipes.
