Abstract
Norwegian lichen spp. were studied with regard to content of higher tetrahydroxy fatty acids. The hydroxy acids isolated are of the same type as those previously recorded in Haematomma ventosum. Infra-red spectra of the acids in solid state have been obtained in the region from 4 000 to 700 cm"1 and confirm the similarity. Semi-solid and solid fatty acids were obtained by reduction with hydrogen iodide and Zn. Paper -chromatographic analysis of the products obtained by periodic-acid oxidation of ventosic acid from H. ventosum showed the presence of tetrahydroxy heneicosanoic acid (C21H42O6) and tetrahydroxy docosanoic acid (C22H44O5) in the lichen. Work on Parmelia centrifugae has pointed out the possibility of the presence of tetrahydroxy tricosanoic acid (C23H46O(6) in the lichen.
