Column chromatography of the acetone extract of the lichen Cladina macaronesica (Sephadex LH-20, silica gel and silver nitrate-impregnated silica gel) afforded eight triterpenes identified by chemical and spectral means. α-Amyrenone, lupenone, taraxerol, taraxenone and iso-arborinol acetate were isolated for the first time from lichens and (-)-usnic acid and five mononuclear phenolic compounds were also obtained, four for the first time as natural products. The possible transformation of perlanolic acid into these phenolic compounds is briefly outlined.
