NO.1.What's Alginic Acid?

Alginic acid, named as Alginate, is a natural polysaccharide extracted from seaweed. It is made of two types of aldehyde acids with D-mannose uronic acid and L-Gu Luo uronic acid.Its apperance is light yellow powder and insoluble.

Alginic acid, also called algin or alginate, is a polysaccharide distributed widely in the cell walls of brown algae, where through binding with water it forms a viscous gum. It is also a significant component of the biofilms produced by the bacterium Pseudomonas aeruginosa, the major pathogen in cystic fibrosis,[1] that confer it a high resistance to antibiotics and killing by macrophages. Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular or powdered forms.

Alginic acid is a linear copolymer with homopolymeric blocks of (1-4)-linked β-D-mannuronate (M) and its C-5 epimer α-L-guluronate (G) residues, respectively, covalently linked together in different sequences or blocks. The monomers can appear in homopolymeric blocks of consecutive G-residues (G-blocks), consecutive M-residues (M-blocks) or alternating M and G-residues (MG-blocks).

Properties of Alginic Acid:
1. Apperance: white or light yellow powder
2. Insoluble in water, odorless and almost tasteless
3. High swell type, with swelling coefficient minimum 22

The extract can be taken as a supplement, and the dried leaves of the plant can be used to make tea.

Ginkgo biloba extract is a commonly used traditional Chinese medicine for the treatment of cardiovascular and cerebrovascular diseases. The active constituents are mainly ginkgo flavonoids and ginkgo biloba lactones. Among them, gingko flavonoids mainly include quercetin, kaempferol and isoflavone. Prime. Ginkgo biloba internal lipids mainly include ginkgolides A, B, C, J, M and biloba lactone.

Ginkgo biloba extract has anti-oxidative activity, cardiovascular activity, anti-inflammatory activity and anti-tumor activity. It can dilate the cerebral blood vessels and arteries, and also has a good protective effect on microvessels, effectively preventing vascular vascular occlusion. Blood lipids, hypertension, diabetes and other symptoms have a good preventive effect,indirectly reducing the incidence of common eye diseases (cataracts, glaucoma, vitreous opacity, retinopathy, diabetes and other common eye diseases), can effectively purify the blood It strengthens blood vessels, prevents heart disease, and is effective against brain disorders, anti-aging, and cancer prevention.

In the last 10 years, American consumers have been using Ginkgo biloba products as a health food to prevent stroke and coronary
heart disease. According to a recent report in the American Journal of Medicine, researchers in the Department of Medicine at Oregon State University in the United States have found that oral ginkgo leaf preparations for the elderly over 65 years of age can effectively prevent memory degradation and Alzheimer's disease.
