The fatty acid compositions of the moss species Atrichum undulatum (Hedw.) P. Beauv. (Polytrichaceae) and Hypnum andoi A.J.E. Sm. (Hypnaceae) collected in winter time were analysed by gas chromatography (GC) and gas chromatography mass spectrometry (GC-MS) as a contribution to their chemistry. Eight fatty acids were identified in the chloroform/methanol extract 1:1 of A. undulatum (linoleic acid, 26.80%, palmitic acid, 22.17%, alpha-linolenic acid, 20.50%, oleic acid, 18.49%, arachidonic acid, 6.21%, stearic acid, 3.34%, cis-5,8,11,14,17-eicosapentaenoic acid, 1.52% and behenic acid, 1.01%), while six fatty acids were found in the same type of extract of H. andoi (palmitic acid, 63.48%, erucic acid, 12.38%, stearic acid, 8.08%, behenic acid, 6.26%, lignoceric acid, 5.16% and arachidic acid, 4.64%). According to this study, the moss A. undulatum can be considered as a good source of both essential fatty acids for humans (linoleic acid and alpha-linolenic acid) during the winter.
Kao doprinos izučavanju njihovog hemijskog sastava, u ovom radu GC i GC-MS analizom ispitivane su masne kiseline mahovina Atrichum undulatum (Hedw.) P. Beauv. (Polytrichaceae) i Hypnum andoi A.J.E. Sm. (Hypnaceae) sakupljene za vreme zimskog doba. U ekstraktu hloroform/metanol 1:1 vrste A. undulatum identifikovano je osam viših masnih kiselina (linolna kiselina, 26,80%, palmitinska kiselina, 22,17%, α-linolenska kiselina, 20,50%, oleinska kiselina, 18,49%, arahidonska kiselina, 6,21%, stearinska kiselina, 3,34%, cis-5,8,11,14,17-eikosapentaenska kiselina, 1,52% i behenska kiselina, 1,01%), dok je u istom ekstraktu vrste H. andoi nađeno šest viših masnih kiselina (palmitinska kiselina, 63,48%, erukinska kiselina, 12,38%, stearinska kiselina, 8,08%, behenska kiselina, 6,26%, lignocerinska kiselina, 5,16% i arahidinska kiselina, 4,64%). Dobijeni rezultati ukazuju da u ispitivanom vremenskom periodu mahovina A. undulatum predstavlja dobar izvor linolne i α-linolenske kiseline, esencijalnih... masnih kiselina za ljude.
