Czeczuga, Bazyli
Column-, and thin-layer chromatography revealed the presence of the following carotenoids in the thalli of 29 lichen species from Białowieża Forest: α-carotene, β-carotene, α-cryptoxanthin, β-cryptoxanthin, lutein, 3'-epilutein, zeaxanthin, β-carotene monoepoxide, lutein epoxide, antheraxanthin, 3'-hydroxyechinenone, α-doradexanthin, canthaxanthin, astaxanthin, neoxani thin, violaxanthin and mutatoxanthin. The total content of carotenoids ranged from 16.83 (Cladonia rangiferina) to 92.98 µg g dry wt (Xanthoria parietina). There were differences in carotenoid composition, concentration of each carotenoid, and in the total content in the thalli of four species collected from niches with different insolation.
