Abstract

In adults of both sexes of Euphausia superba analysed in total without alimentary tract there were identified with help of chromatographic and spectrophotometric methods: β-carotene, free and ester astaxanthine, cantaxanthine, β-cryptoxanthine. lutein and dihydroxy-ζ-carotene, and additionally in females zeaxanthine and flavoxanthine. However, particular parts of body (with an exception of eyes, legs and trunk) and especially the exosceleton cotain less carotenoids, mainly carotene and astaxanthine.

Abstract

It appears from the analysis of the chemical composition of macroalgae of the Antarctic: Adenocystis utricularis and Himantothallus grandifolius (brown algae), Leptosomia simplex (red algae) and Monostroma hariotti (green algae) that the examined algae, brown algae in particular (mainly Adenocystis utricularis), are rich in mineral components, primarily: sodium, potassium, hologens, and structural polysaccharides. Organic substances, such as: proteins, amino acids, lipids, fatty acids, saccharides reduction, chlorophylls and carotenoids, occur in the analysed algae in quantities much smaller in comparison with taxonomically similar macroalgae derived from marine environment having more favourable hydrochemical and climatic conditions.
