Chemical Investigation of the Lichen Species Alectoria ochroleuca, Stereocaulon vesuvianum var. pulvinatum and Icmadophila ericetorum

Abstract

The three lichen species Alectoria ochroleuca, Stereocaulon vesuvianum var. pulvinatum and lcmadophila ericetorum have been chemically investigated with regard to their content of aliphatic and aromatic compounds. Tetrahydroxy fatty acids were isolated in all three species. A mono-acetylated pentol, higher fatty acids and an unsaturated triglyceride were detected as new constituents of A. ochroleuca and I. ericetorum. S. vesuvianum and I. ericetorum both contained phenolic components which not previously have been discussed in literature. Chemical and spectroscopic evidences are presented in these studies. © 1977, Verlag der Zeitschrift für Naturforschung. All rights reserved.
