21 species of common Norwegian lichens were investigated for their content of choline, ergosterol and tocopherols. The choline content varied 20‐fold between species, but most lichens were good sources of choline. Law but significant concentrations of ergosterol were found in many of the samples, indicating the value of these plants as a reserve of vitamin D. a‐Tocopherol was the only member of the vitamin E group detected in the lichens. The contents were higher than those found in blue‐green algae, the phycobionts of many lichens. A new technique for the determination of ergosterol, based on chromatography on alumina‐containing paper, was developed.
