Investigations on carotenoids in Embryophyta. IV. The presence of apocarotenals in peatmosses

By means of column and thin-layer chromatography, the author investigated tit presence of various carotenoids in stems of 3 species of the Sphagnum genus. Apocarotenals (β-apo-2', β-apo-10' -carotenal and apo-12' -violaxanthal) and the following carotenoids were found: α-, β-,;-carotene, β-cryptoxantin, lutein, lutein epoxide, zeaxanthin, adonixanthin, antheroxanthin, rhodoxanthin, rubixanthin, neoxanthin, vio-laxanthin and mutatoxanthin. The total content of carotenoids ranged from 11.954 to 41.579 mg•g-1 dry weight.
