The Study of Compounds Distilled with Water Vapor in Cetraria islandica (L.) Ach. Thalli Harvested in Ukraine

Abstract

The component composition and the quantitative content of compounds distilled with water vapor in the thalli of Cetraria islandica (L.) Ach. harvested in Ukraine were determined using the method of gas chromatography with mass spectrometric detection (GC/MS). 24 compounds distilled with water vapor were identified with the prevalence of fatty acids and their derivatives (57.86±2.00% of the total compounds), terpenoids and their derivatives (23.57±0.97% of the total compounds) and acyclic saturated hydrocarbons (10.99±0.45% of the total compounds). The highest percentage was observed for octadecadienoic (linoleic) acid (20.08±0.67% of the total compounds), hexadecanoic (palmitic) acid (19.21±0.77% of the total compounds) and 9,17-octadecadienal (18.57±0.56% of the total compounds). The presence of 4 monoterpenoids and 6 sesquiterpenoids in the raw material studied was determined for the first time.
