Chemistry of fungi: study of the lipid metabolites of Hydnellum ferrugineum

espanolEn este trabajo se abordo el estudio quimico de la fraccion lipidica del hongo Hydnellum ferrugineum mediante tecnicas espectroscopicas y cromatograficas, en el cual fueron identificados: n-alkanos naturales (C10 – C30), esteroides con el esqueleto del ergosterol (ergosta-7-en-3-ona, ergosta-7,22-dien-3-ona, ergosta-7-en-3β-ol y ergosta-7,22-dien-3β-ol), dos triterpenos pentaciclicos (friedelina y taraxerol), acidos grasos saturados (C11, C12, C13, C14, C15, C16, C17, y C18), oleato de etilo y linoleato de etilo. Es de esperar que esta informacion quimicoespecifica aporte nuevos datos para la clasificacion quimico-taxonomica de este hongo EnglishIn this work we explored a chemical study of the lipid fraction of the fungus Hydnellum ferrugineum through spectroscopic and chromatographic techniques, in which the following were identified: natural n-alkanes (C10 – C30); steroids with an ergosterol skeleton (ergosta-7-en-3-one, ergosta-7,22-dien-3-one, ergosta-7-en-3β-ol and ergosta-7,22-dien-3β-ol); two pentacyclic triterpenes (friedeline and taraxerol); saturated fatty acids (C11, C12, C13, C14, C15, C16, C17, and C18); ethyl oleate; and ethyl linoleate. This chemical-specific information is expected to provide new data for the chemical-taxonomic classification of this fungus
