Flammulina velutipes is a kind of mushroom that is deeply loved by everyone. It is not only delicious food, but also has good health care and medicinal value.
Flammulina velutipes is very nutritious, rich in protein, B vitamins, vitamin C, calcium, phosphorus, iron and other minerals. According to the determination, the amino acid content of Flammulina velutipes is very rich, higher than that of common mushrooms, especially the content of lysine is particularly high, and lysine has the function of promoting children's intellectual development.
Flammulina velutipes also contains active substances such as polysaccharides, taurine, ophiosterol, cytolytic toxins, mushroom cytotoxins, etc. Regular consumption can enhance the body's immunity, lower cholesterol, prevent liver diseases and gastrointestinal ulcers, and prevent cardiovascular and cerebrovascular diseases And so on.
Nutrient composition
1. Anti-tumor
Flammulina velutipes polysaccharides isolated and purified from Flammulina velutipes have obvious anti-tumor activity, mainly inhibiting tumor cell growth through anti-oxidation and scavenging free radicals, interfering with tumor cell biochemical metabolism and mitosis, and inducing tumor cell apoptosis to resist tumors.
2. Fat-lowering
The dietary fiber in Flammulina velutipes cannot be decomposed by enzymes in the human body and absorbed by the digestive tract, but it can combine with cholesterol and bile acid to reduce the accumulation of bile acid in the human liver, promote the metabolism of cholesterol into bile acid, reduce the cholesterol content in the small intestine of the human body, and interfere with Lipid absorption in the small intestine. The polyphenol compounds extracted from Flammulina velutipes also have the effect of delaying the oxidation of LDL and have the potential to treat atherosclerosis.
3. Protect the liver
α-(1→4)-D-glucan isolated from Flammulina velutipes is a water-soluble polysaccharide (FVP2), which can enhance the growth of primary liver cells in mice and inhibit the acute liver injury caused by carbon tetrachloride. Intracellular alanine aminotransferase (ALT) release in rat liver. In addition, Flammulina velutipes polysaccharides can also increase the activity of superoxide dismutase in liver cells, enhance the ability of cells to scavenge free radicals, reduce the damage of free radicals to cell membranes, inhibit lipid peroxidation, and have the effect of protecting the liver.
4. Improve memory
Flammulina velutipes polysaccharide can effectively improve the memory dysfunction induced by scopolamine in rats. Treating rats with Flammulina velutipes polysaccharides can effectively prevent the reduction of the activity of antioxidant defense enzymes in rats, prevent the increase in the content of thiobarbituric acid reactants in rats caused by scopolamine, and improve the oxidative stress response in the brain. Brain injury diseases such as Alzheimer's disease caused by the loss of basal cholinergic neurons, the production of reactive oxygen species in the brain and the imbalance of oxidase action provide a drug basis.
5. Anti-fatigue
Flammulina velutipes polysaccharide solution can significantly reduce gastrocnemius muscle contraction in a dose-dependent manner. Flammulina velutipes polysaccharide can significantly reduce the serum creatine kinase and urea nitrogen content of exercise fatigue rats through immune regulation, increase the activity of lactate dehydrogenase in rat blood, accelerate the clearance of blood lactic acid in the recovery period of rats after exercise, and promote functional recovery.
Clinical application
According to relevant literature reports, YAD-1 cells were used as target cells to measure the transformation rate of lymphocytes and the activity of natural killer cells (NK cells). Results: The transformation index of lymphocytes in the control group was 1.23±0.25, and the lethality of natural killer cells was 34.23%±6.45%. The transformation index of lymphocytes in the Flammulina velutipes group was 1.94±0.43, and the lethality of natural killer cells was 52.53%±7.60%. Show that: the lymphocyte transformation rate and natural killer cell activity of the group taking Flammulina velutipes extract are significantly higher than those of the control group. Further show that Flammulina velutipes has the effect of improving immunity.
