NIETO R., Ivonne J.  and  CUCAITA V., Edna del P.. FATTY ACIDS, ESTERS AND STEROLS OF THE Laccaria laccata MUSHROOM. Rev.Colomb.Quim. [online]. 2007, vol.36, n.3, pp.277-284. ISSN 0120-2804.

From the extract in ethyl acetate of the eatable fungus Laccaria laccata were isolated three fatty acids, 6 ethylic esters, 5 sterols and an ergostanic triterpene. The compounds were identified by M.S. as palmitic, linoleic and oleic acid, ethyl Hexadecanoate, ethyl 8-octadecenoate, ethyl 9-octadecenoate; 9,12-ethyl octadecadienoate, ethyl estearate, ethyl eicosanoate, ergost-2,5,7,9(11),22-pentaene, ergost-5,7,22-triene-3β-ol (ergosterol), ergost-7-22-diene-3β-ol, ergost-7- ene-3β-ol, ergost-5,7,9 (11),22-tetraen- 3β-ol and estigmast-5-ene-3β-ol. The esters and the two latter compounds are reported by first time in the Laccata mushroom.

Keywords : Sterols; macromycete; eatable fungus; Laccaria laccata; fatty acids.
