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. The antioxidant activity of dry extracts of fucus algae has been tested by comparing samples with quercetin, which belongs to a group of plant flavonoids. As a result of the study, a high antiradical activity of all the extracts studied with respect to the DPPH radical has been established. The greatest antiradical activity is characteristic of extracts from the Fucus vesiculosus. The IC50 value (0.035–0.038 mg/ml) has been compared to the IC50 of the quercetin comparison agent (0.026 mg/ml).

Предложен новый способ получения антиоксидантных комплексных экстрактов из фукусовых водорослей на примере трех массовых видов Баренцева моря Fucus vesiculosus, Fucus serratus и Fucus distichus. Изучен химический состав и антиоксидантная активность новых фитокомплексов. Показано высокое значение основных антиоксидантов: фукоидана, полифенолов, свободных аминокислот и аскорбиновой кислоты. Для наиболее важных с точки зрения антиоксидантной активности показателей (фукоидан, полифенолы, аскорбиновая кислота) рассчитан технологический выход в пересчете на содержание БАВ в сухом сырье. Применение нового способа позволило достичь наиболее полной извлекаемости из водорослевого сырья полифенолов и аскорбиновой кислоты (более 90 %) с одновременным увеличением процентной доли этих веществ в экстрактах фукусовых водорослей (25–30 % для полифенолов). Содержание фукоидана в количестве 50–60 % также выгодно отличает полученные по разработанному способу сухие экстракты от экстрактов, описанных в литературе. Проведены испытания антиоксидантной активности сухих экстрактов фукусовых водорослей путем сравнения образцов с кверцетином, который относится к группе растительных флавоноидов. В результате исследования установлена высокая антирадикальная активность всех исследуемых экстрактов по отношению к DPPH радикалу. Наибольшая антирадикальная активность характерна для экстрактов из фукуса пузырчатого. Значение IC50 (0,035–0,038 мг/мл) сопоставлялось с IC50 вещества сравнения кверцетина (0,026 мг/мл).
