Evernia prunastri has proved to be a particularly rich source of lichen compounds and extraction and g.c. — m.s. studies have revealed the presence of orcinol (99) 268, 269), 3-methoxy-5-methylphenol (100) 144), 3,5-dimethoxytoluene (101) 144), 2-chloro-3,5-dimethoxytoluene (102) 144), phenol 144), thymol 144), 2-chloro-3-methoxy-5-methylphenol (103) 144), methyl salicylate 144), methyl 4-O-methylorsellinate (90) 268, 269), and methyl (3-orcinolcarboxylate (104) (255). Rhizonic acid (105) has been isolated from Parmelia subnuda 215). 

After a few minutes 2,4-diamino-6-methylphenol (hRf 5-10), 3-chloro-4-methoxy-aniline (hJ f 25-30), aniline (hRf 35-40), 4-bromoaniline (hRf 40-45), 3-chloroaniline (hJ f 50-55), 2,6-dimethylaniline (hi f 60-65), 2-methyl-6-ethylaniline (hi f 65-70) and 2-chloroaniline (hRj 70-75) yielded orange-colored chromatogram zones on a yellow background. The detection limits were between 5 ng (2,4-diamino-6-methylphenol) and 30 ng (2,6-dimethylaniline) substance per chromatogram zone.
