[Studies on chemical constituents of 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 spectral analysis (IR, EL-MS, FAB-MS, 1H-NMR, 13NMR).


RESULTS
Seven compounds were identified as cyclo-(R-pro-R-leu) (1), cyclo-(R-isoleu-R-leu) (2), phenylalanine (3), alanine (4), leucine (5), guanosine (6), adenosine (7),


CONCLUSIONS
The compounds 1-6 were isolated from the mycelia of Flammulina velutipes for the first time.
