| Studies on the Chemistry of the Lichen Genus Umbilicaria Hoffm  | | | | Abstract
| The aromatic com pounds o f more than 400 specimens o f 33 species o f the lichen genus Umbilicaria have been investigated by HPLC. Additionally to gyrophoric, hiascic, lecanoric, ovoic and umbilicaric acids, atranorin, norstictic and stictic acids, the new depside crustinic acid has been found. Structure elucidation o f crustinic acid was made by means o f HPLC cochromatography, N M R , UV and mass spectrometry. N ow the secondary product patterns o f Umbilicaria species are discussed and their significance for systematic purposes is shown. | | | |
