Embodiment 1
[0040] The preparation method of scorpion grass polysaccharide, concrete steps are:
[0041] a. Preprocessing
[0042] Grind the scorpion grass, put the fine powder into the reflux extraction device, add ethanol with a volume fraction of 95% equivalent to 5 times the weight of the scorpion grass, reflux extraction for 2 hours, filter, discard the filtrate, and then add a volume equivalent to 5 times the weight of the scorpion grass The fraction is 95% ethanol, reflux extraction for 2 hours, filter, discard the filtrate, and obtain the pretreated Scorpion grass;
[0043] b. Extraction
[0044] Add water equivalent to 20 times the weight of scorpion grass obtained in step a, extract at a temperature of 85°C for 1.5 hours, filter, collect the filtrate, and then add 20 times the weight of scorpion grass to the medicinal residues times of water, at a temperature of 85°C, extract for 1.5 hours, filter, and collect the filtrate; combine the two filtrates to obtain the extract;

[0053] The preparation method of scorpion grass polysaccharide, concrete steps are:
[0054] a. Preprocessing
[0055] Grind the scorpion grass, put the fine powder into the reflux extraction device, add ethanol with a volume fraction of 90% equivalent to 10 times the weight of the scorpion grass, reflux extraction for 1 hour, filter, discard the filtrate, and then add a volume equivalent to 10 times the weight of the scorpion grass The fraction is 90% ethanol, reflux extraction for 1 hour, filter, discard the filtrate, and obtain the pretreated scorpion grass;
[0056] b. Extraction
[0057] Add the pretreated scorpion grass obtained in step a to water equivalent to 5 times the weight of the scorpion grass, and extract at a temperature of 90°C for 3 hours, filter, collect the filtrate, and then add an amount equivalent to the pretreated scorpion grass to the medicinal residues 30 times the weight of water, at a temperature of 90°C, extract for 1 hour, filter, collect the filt...
