Supercritical Fluid Extraction of Chlorophylls and Carotenoids from White Sea Algae

The supercritical fluid extraction of chlorophyll and carotenoids from marine algae Fucus Vesiculosus and Laminaria Digitata with carbon dioxide is studied. Carotenoids can be completely extracted by pure CO2 during 20 min at 250 atm and 80 °C. To obtain extracts with high content of chlorophylls, the addition of 10—15% vol. ethanol (polar co-solvent), or prolonged extraction (50—90 min) at ethanol concentration < 5% vol. are required.

Key words: chlorophyll, carotenoids, supercritical fluid extraction, Fucus vesiculosus, Laminaria digitata, plant raw materials
