MARQUEZ-FERNANDEZ, Olivia; JUAREZ PACHECO, Luis Á.  and  TRIGOS, Ángel. Isolation and identification of sterols in a commercial strain of Pleurotus sp. Rev. Chapingo ser. cienc. for. ambient [online]. 2014, vol.20, n.2, pp.227-235. ISSN 2007-4018.  https://doi.org/10.5154/r.rchscfa.2013.12.044.

Five compounds in a commercial strain of the mushroom Pleurotus sp. were obtained from ethyl acetate and methanol extracts. The compounds were isolated using techniques such as column and thin layer chromatography. The following sterols were identified by ¹H NMR spectroscopy: 1) ergosta-5,7,22-trien-3β-ol (ergosterol), 2) 5α, 8α-epidioxy-22E-ergosta-6, 22-dien-3β-ol (ergosterol peroxide), 3) 3β,5α,6β,9α-tetrahidroxiergosta-7,22-dieno, 4) 3β, 5α, 6β, 9α-tetrahydroxyergosta-7, 22-dien and 5) 3β, 5α, 9α-trihidroxiergosta-7,22-dien-6-one.

Keywords : Mushrooms; functional foods; active secondary metabolites.
