Studies on the Chemistry of Lichens
نویسنده
چکیده
The Norwegian lichen species Lecanora (Aspicilia) Myrinii has been chemically investigated with regard to its content of aromatic lichen compounds, hydroxy fatty acids, soluble and bound sugars, and amino acids. Norstictic acid and a tetrahydroxy fatty acid have been isolated. In addition to these two compounds, free galactose, glucose, mannose, sucrose, fructose and 33 ninhydrin-positive compounds were detected in a water extract. The polysaccharides and the protein part of the lichen material were determined after hydrolysis. Great amounts of glucosamine were found in the protein fraction.
