The lichen substances com- prise quite different classes of compounds like amino acid derivatives, sugar alcohols, aliphatic acids, 'Y-, 0- and macrocyclic lactones, mono cyclic aromatic compounds, quinones, chromones, xanthones, dibenzofuranes, de- psides, depsidones, depsones, terpenoids, ste- roids and carotenoids. This multitude of compounds made the study of their chemistry attractive from the early times of organic chem- istry. Bebert (1831) isolated vulpinic acid in 1831, Alms (1832) picrolichenic acid in 1832, and Knop (1844) usnic acid in 1844. Gmelin (1858) published a review on lichen substances already in 1858. The classical period of lichen chemistry is connected with two names: W. Zopf and O. Hesse. W. Zopf (Fig. 1) was a botanist (born 1846 at Ro:Bleben, Thuringia, Germany, died 1909 at Miinster/Westfalen) and published a series of papers on lichen substances which he summarized in the well-known book Die Flechtenstoffe in chemischer, botanischer, pharmakologischer und technischer Beziehung, published in 1907.
