Abstract:
OBJECTIVETo study the chemical constituents from the mycelia of Flammulina velutipes.
METHODThe 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).
RESULTFive 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).
CONCLUSIONThe compounds (2)-(5) were isolated for the first time from the mycelia of Flammulina velutipes.
