This handbook is an indispensable tool for the isolation, identification and structural analysis of the approx. 700 substances currently known to occur in lichens. The first part covers all necessary methods for the analysis of lichen metabolites; the second part gives the analytical and spectroscopical data of all known lichen substances as well as a key to their identification and differentiation.
Besides its high value for all chemists working with these substances as a basis for other products, the book serves as a chemotaxonomical key to the identification of lichen species and as a reference for all those who use lichens for the biomonitoring of environmental pollution.
