The antiradical activity (ARA) of 11 species of macrophyte algae in the northern part of the Sea of Okhotsk was analyzed for the first time. The highest ARA indicators were established for cystozera, ulva and fucus and exceeded the traditionally eaten kelp by 1.2-2.2 times. Oil infusions of kelp showed an increase in ARA scores by 13% compared to its alcoholic extracts. Average ARA values decreased in the following sequence: brown (with scatter of data), green, red algae. Despite the low ARA values, in red algae (≈ 33% of the maximum value), the effect of an increase in the viscosity of hot solutions was found when using algae of the genus Chondrus, which, in our opinion, was explained by the presence of caraginans. Assessment of the fall in ARA during storage of dried products from whole algae revealed a decrease in the value of this parameter ≈ 2.5% per month.
