Antioxidant complex extracts from fucus algae of the Barents Sea

A new method for obtaining antioxidant complex extracts from fucus algae has been proposed at the example of three mass species of the Barents Sea: Fucus vesiculosus, Fucus serratus and Fucus distichus. The chemical composition and antioxidant activity of new phytocomplexes has been studied. The high value of the main antioxidants - fucoidan, polyphenols, free amino acids and ascorbic acid - has been shown. For the most important indicators from the antioxidant activity point of view (fucoidan, polyphenols, ascorbic acid), a technological yield has been calculated in terms of the content of BAS in dry raw materials. The use of the new method has made it possible to achieve the most complete extraction of polyphenols and ascorbic acid (over 90 %) from algal raw materials with the simultaneous increasing the percentage of these substances in extracts of fucus algae (25-30 % for polyphenols). The content of fucoidan equal to 50-60 % also advantageously distinguishes the dry extracts obtained by the developed method from the extracts described in the literature...
