An insight into fatty acid chemistry of Rhytididelphus squarrosus (Hedw.) Warnst

Abstract

The fatty acid composition of the moss Rhytididelphus squarrosus (Hedw.) Warnst. (Hylocomiaceae) collected in Germany during winter time was analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Nine fatty acids were identifi ed in its chloroform:methanol extract 1:1: arachidonic acid (30.7%), α-linolenic acid (19.1%), linoleic acid (15.1%), cis-5,8,11,14,17-eicosapentaenoic acid (14.4%), palmitic acid (11.9%), cis-8,11,14- eicosatrienoic acid (4.1%), oleic acid (2.3%), γ-linolenic acid (1.4%) and stearic acid (1.0%). Th e results indicate that this plant species can be a good source of arachidonic acid collected during the winter.

Sastav viših masnih kiselina mahovine Rhytididelphus squarrosus (Hedw.) Warnst. (Hylocomiaceae), sakupljene u Nemačkoj za vreme zimskog doba, preliminarno je ispitivan GC i GC-MS analizom. U njenom ekstraktu hloroform: metanol 1:1 identifikovano je devet viših masnih kiselina: arahidonska kiselina (30.7%), α-linolenska kiselina (19.1%), linolna kiselina (15.1%), cis-5,8,11,14,17-eikosapentaenska kiselina (14.4%), palmitinska kiselina (11.9%), cis-8,11,14-eikosatrienska kiselina (4.1%), oleinska kiselina (2.3%), γ-linolna kiselina (1.4%) i stearinska kiselina (1.0%). Dobijeni rezultati ukazuju da je ova biljna vrsta dobar izvor arahidonske kiseline u ispitivanom vremenskom periodu.
