Abstract

Aim. To study the component composition of free and total monosaccharides in the raw material of Cetraria islandica (L.) Ach. harvested in Ukraine.Materials and methods. The component composition of free and total monosaccharides in the raw material was determined by gas chromatography with mass-spectrometric detection (GC-MS).Results and discussion. Among the free monosaccharides, the presence of D-perseitol, (6.99 mg g–1) and D-mannitol (1.12 mg g–1) was determined. Among the total monosaccharides, the content of D-glucose (203.64 mg g–1) prevailed. D-mannose (53.74 mg g–1), D-galactose (51.71 mg g–1), D-xylose (0.83 mg g–1) and L-rhamnose (0.53 mg g–1) were found in lower quantities, as well as polyatomic alcohols – D-dulcitol (8.46 mg g–1) and D-mannitol (3.10 mg g–1).Conclusions. For the first time, the component composition of free and total monosaccharides in the raw material of C. islandica harvested in Ukraine has been determined. The results obtained will be used as a component of the comprehensive systematic study of the raw material of C. islandica harvested in Ukraine.

岛天竺葵(Cetraria islandica)碳水化合物组成研究课时。在乌克兰收获的大肚菌

的目标。研究天竺葵原料中游离单糖和总单糖的组成。课时。在乌克兰收获。材料和方法。采用气相色谱-质谱联用检测(GC-MS)法测定原料中游离单糖和总单糖的组成。结果和讨论。在游离单糖中，测定了d -海塞糖醇(6.99 mg g-1)和d -甘露醇(1.12 mg g-1)的含量。在总单糖中，d -葡萄糖含量最高，为203.64 mg g-1。d -甘露糖(53.74 mg g-1)、d -半乳糖(51.71 mg g-1)、d -木糖(0.83 mg g-1)和l -鼠李糖(0.53 mg g-1)的含量较低，以及多原子醇- D-dulcitol (8.46 mg g-1)和d -甘露醇(3.10 mg g-1)。首次测定了产自乌克兰的岛c原料中游离单糖和总单糖的组成。所获得的结果将被用作乌克兰收获的岛c原料的全面系统研究的组成部分。
