SAN-MARTIN, AURELIO et al. STEROIDS FROM THE MARINE FUNGUS GEOTRICHUM SP. J. Chil. Chem. Soc. [online]. 2008, vol.53, n.1, pp.1377-1378. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072008000100011.

Ergosterol 1, peroxyergosterol 2, ergosta-4,6,8(14), 22-tetraen-3-one 3 and 24-ethyl-cholesta-4-ene-3-one 4 were isolated from the cultures of a fungus Geotrichum sp. obtained from a marine sediment. It was established that no other sterols were present in the extract. Their structures were elucidated by spectroscopic methods

Palavras-chave : sterols; ergostane type sterol; ergosterol; peroxyergosterol; marine fungus.
