Using DPPH free radical as an in vitro antioxidant model and using ascorbic acid (Vc) as a positive control, the four important marine activities of trehalose, carboxymethyl chitosan, glucosamine hydrochloride and corona bafil clam small molecule peptides 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 activity and concentration show a certain dose-effect relationship. The small molecular peptide of corrugated paphia is better at eliminating DPPH free radicals than the other two marine species. Active substance, when the concentration is 4 g/L, the elimination rate of DPPH radicals reaches 95.7447%.
