Laminaria is an important plant with both medicinal and edible properties. It contains high levels of laminarin, mainly fucoidan, fucoidan and brown algae starch.
In addition, it also contains acidic polysaccharides, laminarin FGS and zosteramin. Its biological activity is related to the laminarin content it contains, which accounts for 20% to 70% of its dry weight.
The extraction methods of laminarin include enzyme extraction, water extraction, ultrasonic method, acid treatment, alkali treatment, microwave method, etc.
