Embodiment 1
[0033] The extraction of Hericium erinaceus anti-allergic activity polysaccharide specifically comprises the following steps:
[0034] (1) After drying Hericium erinaceus, crush and pass through a 80-mesh sieve to obtain Hericium erinaceus powder, take 50g of Hericium erinaceus powder, add 1000mL of distilled water, bathe in 80℃ water for 5h, centrifuge at 3000r / min for 20min, and collect the extract , to obtain the crude extract of Hericium erinaceus polysaccharide;
[0035] (2) The crude extract of Hericium erinaceus polysaccharides was vacuum concentrated to a solid content of 10%, then mixed with Sevage reagent (chloroform:n-butanol=5:1, volume ratio) at a volume ratio of 4:1, and deproteinized 5 times, centrifuge at 3000r / min for 20min each time; after removing the Sevage reagent by vacuum rotary evaporation, mix with D315 macroporous resin at a volume ratio of 10:3, stir for 5h, and filter;
[0036] (3) Transfer the crude extract obtained from the final filtration of st...

[0042] The extraction of Hericium erinaceus anti-allergic activity polysaccharide specifically comprises the following steps:
[0043] (1) After drying Hericium erinaceus, crush and pass through an 80-mesh sieve to obtain Hericium erinaceus powder, take 80g of Hericium erinaceus powder, add 2400mL of distilled water, bathe in 85℃ water for 6h, centrifuge at 4000r / min for 30min, and collect the extract , to obtain the crude extract of Hericium erinaceus polysaccharide;
[0044] (2) The crude extract of Hericium erinaceus polysaccharides was vacuum concentrated to a solid content of 14%, then mixed with Sevage reagent (chloroform:n-butanol=5:1, volume ratio) at a volume ratio of 2:1, and deproteinized 6 times, centrifuge at 4000r / min for 10min each time; remove the Sevage reagent by vacuum rotary evaporation, mix with D315 macroporous resin at a volume ratio of 10:4, stir for 6h, and filter;
[0045] (3) Transfer the crude extract obtained from the final filtration of step (2) to...
Embodiment 3
[0051] The extraction of Hericium erinaceus anti-allergic activity polysaccharide specifically comprises the following steps:
[0052] (1) After drying Hericium erinaceus, crush and pass through a 80-mesh sieve to obtain Hericium erinaceus powder, take 60g of Hericium erinaceus powder, add 1500mL of distilled water, bathe in 75℃ water for 5.5h, centrifuge at 3500r / min for 25min, collect and extract solution to obtain the crude extract of Hericium erinaceus polysaccharide;
[0053] (2) The crude extract of Hericium erinaceus polysaccharides was vacuum concentrated to a solid content of 13%, then mixed with Sevage reagent (chloroform: n-butanol = 5:1, volume ratio) at a volume ratio of 3:1, and deproteinized 8 times, centrifuge at 3500r / min for 15min each time; remove the Sevage reagent by vacuum rotary evaporation, mix with D315 macroporous resin at a volume ratio of 5:1, stir for 7h, and filter;
[0054] (3) Transfer the crude extract obtained from the final filtration of ste...
