Embodiment 1
[0031] Described carboxymethyl tuckahoe polysaccharide is prepared by the following method:
[0032] S1. Cultivation of Poria cocos: Aseptically inoculate Poria cocos mycelium in wort liquid medium, and culture at 28°C for 4 days;
[0033] S2. Preparation of Poria cocos polysaccharide: The cultured Poria cocos medium was fermented at 35°C for 2 days, heated to a slight boil, extracted for 1 hour, filtered, and a mixed solvent of 3 times the amount of chloroform and n-butanol was added. The mixing volume ratio is 4:1, shake, centrifuge, add 3 times the amount of 95% ethanol, overnight, filter to get the precipitate, wash twice with ether to obtain Poria cocos polysaccharide;
[0034] S3. Preparation of Poria cocos polysaccharide: add 10 g of Poria polysaccharide to 100 mL of 0.5 mol / L sodium periodate solution for selective oxidation, adjust the pH to 3 with trifluoroacetic acid, moderately acidify, and the acid hydrolysis time is 30 min, filter , the solid was washed with wat...

[0038] Described carboxymethyl tuckahoe polysaccharide is prepared by the following method:
[0039] S1. Cultivation of Poria cocos: Aseptically inoculate Poria cocos mycelium in wort liquid medium, and culture at 28°C for 5 days;
[0040] S2. Preparation of Poria cocos polysaccharide: The cultured Poria cocos medium was fermented at 35°C for 2 days, heated to a slight boil, extracted for 2 hours, filtered, and a mixed solvent of 5 times the volume of chloroform and n-butanol was added. The mixing volume ratio is 6:1, shake, centrifuge, add 3 times the amount of 95% ethanol, overnight, filter to obtain the precipitate, wash with ether 3 times to obtain Poria cocos polysaccharide;
[0041] S3. Preparation of Poria cocos polysaccharide: add 10 g of Poria polysaccharide to 30 mL of 1.5 mol / L sodium periodate solution for selective oxidation, adjust the pH to 4 with trifluoroacetic acid, moderately hydrolyze with acid for 1 h, filter , the solid was washed with water to obtain th...
Embodiment 3
[0045] Described carboxymethyl tuckahoe polysaccharide is prepared by the following method:
[0046] S1. Cultivation of Poria cocos: Aseptically inoculate Poria cocos mycelium in wort liquid medium, and culture at 28°C for 4 days;
[0047] S2. Preparation of Poria cocos polysaccharide: the cultured Poria cocos medium was fermented at 35°C for 2 days, heated to a slight boil, extracted for 2 hours, filtered, and a mixed solvent of chloroform and n-butanol was added, and the mixed volume ratio of chloroform and n-butanol was At 5:1, shake, centrifuge, add 3 times the amount of 95% ethanol, overnight, filter to obtain a precipitate, wash with ether 3 times to obtain Poria cocos polysaccharide;
[0048] S3. Preparation of Poria cocos polysaccharide: add 10 g of Poria polysaccharide to 50 mL of 1.0 mol / L sodium periodate solution for selective oxidation, adjust the pH to 3.6 with trifluoroacetic acid, moderately acidolyse, the acidolysis time is 45min, filter , the solid was washe...
