摘要

Ergosterol (1) under bar, peroxyergosterol (2) under bar, ergosta-4,6,8(14), 22-tetraen-3-one (3) under bar and 24-ethyl-cholesta-4-ene-3-one (4) under bar 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.
