Abstract
113 specimens of Lepraria jackii, for the most part from Central Europ e were analysed by lichen mass spectrometry and/or by thin layer chrom atography. Regularly occurring major compounds are atranorin and the f atty acids jackinic and/or roccellic acid. Jackinic acid and its minor compound norjackinic acid are hitherto unknown lichen substances. The accessoric zeorin is rarely found occurring in variable amounts. The sporadic occurrence of 6-methyl-pannarate, usnic, gyrophoric or sticti s acids is interpreted as contamination.
