Known terpenoids from lichens are all shared with higher plants or marine organisms, including monoterpenoid (-)-carvone 45, sesquiterpenoid bakkenolide A/fukinanolide A 46 from Cetraria islandica (Solberg 1986), triterpenoids [alpha]-amyrin 47, friedelan-3[beta]-ol/epifriedelinol 48, lupeol 49 and ursolic acid 50 from Flavocetraria nivalis (Bruun 1969) and zeorin 51 in the Vulpicida genus (Randlane et al.
Among the selected lichens are four cetrarioid lichens, including Cetraria islandica, Flavocetraria nivalis, Melanelia hepatizon and Vulpicida pinastri.
