Composition and efficacy of shiitake mushroom extract

Shiitake mushroom extract is mainly used as a raw material for medicine and health food. Shiitake mushroom polysaccharides are anti-tumor components with a molecular weight of 1 million. In addition, they also contain components that lower blood lipids - shiitake mushroom too raw, shiitake mushroom adenine, and derivatives of adenine. Mushroom extract contains high levels of unsaturated fatty acids, as well as a large amount of ergosterol and mycosterol that can be converted into vitamin D. It has a good effect on enhancing resistance to diseases, preventing colds, and treating them. Regular consumption is beneficial for preventing rickets caused by blood phosphorus and blood calcium metabolism disorders, especially in infants due to vitamin D deficiency. It can also prevent various mucosal and skin inflammatory diseases in the human body. The shiitake mushrooms contained in shiitake mushrooms can prevent arteriosclerosis, lower blood pressure, and also isolate components that lower serum cholesterol from shiitake mushrooms.
Composition properties
Dried shiitake mushrooms account for 72% of the total, with 18.64g of crude protein, 4.8g of crude fat, 61.4g of carbohydrates, 9.6g of crude fiber, 1548.08kJ of calories, and 5.5g of ash per 100g of dried product. The main components are as follows:
1. Polysaccharides and proteins
Mushroom polysaccharides are homogeneous components extracted, isolated, and purified from their fruiting bodies. They are the main component and have anti-tumor activity. The molecular formula is (C6H10O5) n, with molecular weights ranging from 16000 to millions. The proteins in shiitake mushrooms are mainly albumin, gluten, and alcohol soluble protein (100:63:2), with molecular weights ranging from 20kDa to 40kDa. Among them, there are mainly 18 amino acids that make up proteins (with the highest content being glutamic acid), including 7 essential amino acids.
2. Steroids
Steroids are a major chemical component in the lipid soluble components of shiitake mushrooms, with a total steroid content of 103.8mg in 100g of the new sample. The compounds that have been isolated from it include common ergosterol and peroxyergosterol.
3. Polyphenols
The total polyphenol content in shiitake mushrooms was measured by colorimetric method to be about 4mg/g (dry weight).
4. Fatty acids
Fatty acid compounds account for about 2% in shiitake mushrooms, with unsaturated fatty acids accounting for about 77%, mainly including oleic acid (8.3%), linoleic acid (68.8%), and linoleic acid (0.6%). Saturated fatty acids mainly include palmitic acid (19.2%), stearic acid (2.7%), and arachidic acid (0.4%).
5. Nucleotide compounds
Nucleic acid compounds include cAMP (cyclic adenosine monophosphate), cGMP (cyclic guanosine monophosphate), and cCMP (cyclic cytidine phosphate). The unique purine compound shiitake mushroom purine, also known as shiitake mushroom extract.
6. Vitamin and mineral compounds
Including calcium, phosphorus, iron, vitamin B1 B2, Niacin, etc.
effect
1. Improve the body's immune function
Mushroom polysaccharides can enhance the phagocytic function of peritoneal macrophages in mice, promote the production of T lymphocytes, and increase the killing activity of T lymphocytes.
2. Delaying aging
The water extract of shiitake mushrooms has a clearing effect on hydrogen peroxide and has a certain elimination effect on hydrogen peroxide in the body.
3. Anti cancer and anti-cancer measures
Another compound found in shiitake mushrooms, shiitake purine (also known as gibberellin), can lower cholesterol levels. Mushrooms contain 12 times more antioxidants than malt and 4 times more antioxidants than chicken liver. Compared with matsutake mushrooms and gray tree flowers (also known as shell leaf porous mushrooms, commonly known as cloud mushrooms, chestnut mushrooms, and lotus mushrooms), it has stronger effects in lowering blood pressure and resisting cancer.
4. Lower blood pressure, blood lipids, and cholesterol
Mushrooms contain purine, choline, tyrosine, oxidase, and certain nucleic acid substances, which can lower blood pressure, cholesterol, and blood lipids, as well as prevent diseases such as arteriosclerosis and cirrhosis.
5. Treat diseases
Lentinula edodes can also be used to treat diabetes, tuberculosis, infectious hepatitis, neuritis, dyspepsia, constipation, etc.
