چکیده (انگلیسی):

The aerial parts of Artemisia absinthium and Artemisia vulgaris are used in infusions for the treatment ofseveral diseases. Besides secondary metabolites, carbohydrates are also extracted with hot water andare present in the infusions. The plant carbohydrates exhibit several of therapeutic properties and theirbiological functions are related to chemical structure. In this study, the polysaccharides from infusionsof the aerial parts of A. absinthium and A. vulgaris were isolated and characterized. In the A. absinthiuminfusion, a type II arabinogalactan was isolated. The polysaccharide had a Gal:Ara ratio of 2.3:1, andmost of the galactose was (1پ¨3)- and (1پ¨6)-linked, as typically found in type II arabinogalactans. Inthe A. vulgaris infusion, an inulin-type fructan was the main polysaccharide. NMR analysis confirmed thestructure of the polymer, which is composed of a chain of fructosyl units -(2پ©1) linked to a starting-d-glucose unit.
