Embodiment 1
[0038] (1) Use red ganoderma lucidum fruiting bodies as raw materials to carry out ultrafine pulverization treatment to obtain red ganoderma powder with a particle size of about 150 meshes. Red ganoderma powder is refluxed twice with 90% ethanol at 80° C. for 3 hours each time. The ratio of solid to liquid is 1:15 (g / ml), then centrifuged to remove the supernatant, and the resulting precipitate is dried in an oven at 60°C for 5 hours to obtain Ganoderma lucidum from which alcohol-soluble components, some monosaccharides, oligosaccharides and lipid substances have been removed pink.
[0039] (2) Accurately weigh 5g of red Ganoderma lucidum powder, wherein the moisture content of red Ganoderma lucidum powder is 13.26%, with water as solvent, the solid-liquid ratio of red Ganoderma lucidum powder and water is 1: 25 (g / ml), first use microwave assisted Hot water extraction followed by ultrasonic-assisted hot water extraction of water-soluble Ganoderma lucidum polysaccharides.

Embodiment 2
[0042] (1) Use red ganoderma lucidum fruiting body as raw material to carry out superfine pulverization treatment to obtain red ganoderma powder with a particle size of about 200 mesh. The ratio of solid to liquid is 1:20 (g / ml), then centrifuged to remove the supernatant, and the resulting precipitate is dried in an oven at 60°C for 5 hours to obtain Ganoderma lucidum from which alcohol-soluble components, some monosaccharides, oligosaccharides and lipid substances have been removed pink.
[0043] (2) Accurately weigh 5g of red Ganoderma lucidum powder, wherein the moisture content of red Ganoderma lucidum powder is 13.26%, with water as solvent, the solid-liquid ratio of red Ganoderma lucidum powder and water is 1: 20 (g / ml), first adopt microwave-assisted Hot water extraction followed by ultrasound-assisted hot water extraction of water-soluble Ganoderma lucidum polysaccharides. Among them, the microwave extraction conditions are: microwave power 400W, extraction time 4min...
Embodiment 3
[0046] (1) Use red ganoderma lucidum fruiting body as raw material to carry out ultrafine pulverization treatment to obtain red ganoderma powder with a particle size of about 100 mesh, red ganoderma powder is refluxed with 95% ethanol at 75°C for 2 times, each time for 3 hours, the mixture of red ganoderma powder and ethanol The ratio of solid to liquid is 1:18 (g / ml), then centrifuged to remove the supernatant, and the resulting precipitate is dried in an oven at 60°C for 5 hours to obtain Ganoderma lucidum from which alcohol-soluble components, some monosaccharides, oligosaccharides and lipid substances have been removed pink.
[0047] (2) Accurately weigh 5g of red Ganoderma lucidum powder, wherein the moisture content of red Ganoderma lucidum powder is 13.26%, with water as solvent, the solid-liquid ratio of red Ganoderma lucidum powder and water is 1: 15 (g / ml), first adopt microwave-assisted Hot water extraction followed by ultrasound-assisted hot water extraction of wat...
