Abstract

RIVERA, Augusto et al. DEHYDROERGOSTEROL: AN ARTIFACT GENERATED DURING EXTRACTION OF STEROLS FROM Pleurotus sajor-caju. Rev.Colomb.Quim. [online]. 2005, vol.34, n.2, pp.117-125. ISSN 0120-2804.

During the extraction of sterolic fraction of Pleurotus sajor-caju was established that dehydroergosterol (ergosta-5,7,9 (11), 22-tetraen-3-ol) present in the extract is possibly not a natural product but an artifact produced during the process of extraction of sterols with chloroform. This was attributed to the presence of phenolic substances in the extract.

Keywords : Pleurotus sajor-caju; culture of fungi; sterols; dehydroergosterol; ergosterol.
