[Studies on chemical constituents in the mycelia from fermented culture of Flammulina velutipes].
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.
