Using hydroxyl radicals as an in vitro antioxidant model and using ascorbic acid (Vc) as a positive control, four important marine activities of trehalose, carboxymethyl chitosan, glucosamine hydrochloride, and rippled paphia small molecule peptide were studied Antioxidant ability of the substance in vitro. The experimental results show that the four marine active substances have good antioxidant properties, and their antioxidant properties show a certain positive correlation with the concentration; carboxymethyl chitosan has a stronger ability to eliminate hydroxyl radicals than the other three marine active substances. When the concentration was 4 g/L, the elimination rate of para-hydroxyl radicals reached 91.71%.
