Flammulina Velutipes--Polysaccharide

How Much Do You Know Flammulina velutipes?

Flammulina velutipes, also known as Pleurotus ostreatus, Pleurotus ostreatus and Tremella villosum. Flammulina velutipes is an edible fungus cultivated in autumn, winter and early spring. It is famous for its smooth and tender cap, crisp handle, rich nutrition and delicious taste.

The main active component of Flammulina velutipes is Flammulina velutipes polysaccharide.Many studies believe that Flammulina velutipes polysaccharide can not only improve human immunity, but also protect liver, moisturize, anti infection, anti-oxidation, assist in improving memory and alleviating physical fatigue.It is a water-soluble polysaccharide from Flammulina velutipes seeds after selection, water extraction, concentration, powder spraying and drying. It is light yellow to brownish yellow powder. Flammulina velutipes polysaccharide is mainly a polymer connected by more than 10 monosaccharides through glycosidic bonds.

Firstly, it has immunoregulation effect. Flammulina velutipes polysaccharide is a kind of immune enhancer, which can enhance T cell function, activating lymphocytes and phagocytes, promoting antibody production, inducing interferon production, and inhibiting tumor growth by restoring and improving the immune function of the whole body.

Secondly, it can protect our liver. Flammulina velutipes polysaccharide can improve the activity of antioxidant enzymes such as SOD, improving the free radical scavenging ability, reducing the damage of free radicals to cell membrane and preventing lipid peroxidation. It may strengthen the free radical scavenging ability of the liver by inducing the activity of liver drug metabolic enzymes, so as to protect the liver.

Next, it owns antioxidation effect. The ability of Flammulina velutipes polysaccharide to scavenge hydroxyl radical was studied. The test showed that Flammulina velutipes polysaccharide had the ability to scavenge hydroxyl radical, and the scavenging rate of Oh gradually increased with the increase of its concentration.

Then, it has anti fatigue effect. The results show that the activity of lactate dehydrogenase, the content of muscle glycogen and liver glycogen in mice treated with Flammulina velutipes for a certain time are significantly higher than those in the control group, which shows that Flammulina velutipes can enhance the adaptability of the body to exercise load, resist fatigue and accelerate the elimination of fatigue.

Lastly, it can help help moisturize. The results of in vivo moisturizing test showed that Flammulina velutipes polysaccharide had better ability to prevent water loss in the cuticle of skin than glycerol.

At present, Flammulina velutipes polysaccharide is mainly used in food and beverage, functional food, meal substitute powder, solid beverage, tablet candy, etc.
