New Results on the Chemistry of Lichen Substances

Abstract: Lichen chemistry continues to be a flourishing branch of natural product chemistry. Since the last major review by Elix et al. in volume 35 of this series (274) many new and interesting lichen substances have been isolated and synthesized. This suggests that an update is desirable. As in the previous articles new methods for structure elucidation and synthesis, biosynthesis, chemotaxonomy and biological activities of lichen substances will be discussed. Some other relatively recent treatments of the subject need to be mentioned: A short chapter by Culberson and Elix (100) in Harborne’s Methods in Plant Biochemistry treated lichen constituents. Several minor reviews were published in 1984 (382), 1991 (385) and 1994 (386). Volume III of Galun’s Handbook of Lichenology (311) contains a chapter on chemical constituents of lichens including secondary metabolic products, storage products of lichens, carotenoids and phycobiliproteins.
