The invention belongs to the technical field of seaweed functional products, and particularly relates to fucoidin as well as a preparation method and application thereof, in particular to application of the fucoidin in food and preparation of medicines for adjuvant treatment of age-related maculopathy. According to the invention, alginate lyase is adopted to carry out enzymolysis on seaweed, and the fucoidin with the molecular weight of 20-60 kDa is obtained after treatment of multi-stage alcohol precipitation, hydrogen peroxide degradation and membrane interception. Experimental results show that the fucoidin has the effect of repairing retinal cells, can effectively improve maculopathy, can be used for preparing related products for treating age-related macular degeneration, and provides safer natural material support for treatment of age-related macular degeneration.
