Embodiment 1
[0040] Example 1: Preparation of water-soluble small molecule active substance containing amino-oligosaccharin from shrimp and crab shells Method 1
[0041] Take 10kg of polyphosphoric acid with a phosphoric acid content of 105%, and 1kg of choline chloride, mix well and add them into a 50L reaction kettle, stir and heat at 85°C for 1 hour to form a polyphosphoric acid-choline chloride deep eutectic solvent composite system ,;
[0042] Shrimp and crab shells were dried until the water content was lower than 10%, crushed and 5 kg was added to the above reaction system, stirred and dissolved at 90°C for 2 hours to form a polyphospholipid solution;
[0043] Add catalyst aqueous solution 1.0% hypoiodous acid aqueous solution 10kg catalytic degradation 2 hours under heat preservation condition, after 50 order gauze filter and remove insoluble matter, form steady-state water-soluble active matter solution; Wherein the insoluble matter weight of filtering gained is 0.39kg.

Embodiment 2
[0048] Example 2: Method 2 for preparing water-soluble small molecule active substances containing amino-oligosaccharins from shrimp and crab shells
[0049] Take 400 kg of polyphosphoric acid with a phosphoric acid content of 105%, and 10 kg of choline chloride are fully mixed and then added to a 2-ton reactor, stirred and heated at 85 ° C for 0.5 hours to form a polyphosphoric acid-choline chloride composite system;
[0050] Dry and pulverize the shrimp and crab shells and add 200kg to the above reaction system, raise the temperature to 85°C and stir to dissolve for 4 hours to form a polyphospholipid solution;
[0051] Under the condition of heat preservation, 150 kg of aqueous catalyst solution and 0.5% hypoiodous acid aqueous solution were added to catalyze degradation for 3 hours, and after removing insoluble matter through 50-mesh gauze filtration, a steady-state water-soluble active substance solution was formed. Wherein the filtered gained insoluble matter weight is 9....
Embodiment 3
[0054] Embodiment 3: Enteromorpha preparation method of water-soluble small molecule active substance
[0055] Take 9 kg of polyphosphoric acid with a phosphoric acid content of 115%, and 2 kg of choline chloride, mix well and add them into a 50L reaction kettle, stir and heat at 85°C for 1 hour to form a polyphosphoric acid-choline chloride composite system;
[0056] Dry and pulverize Enteromorpha enteromorpha and add 4kg to the above reaction system, heat up to 85°C and stir to dissolve for 2 hours to form a polyphospholipid solution;
[0057] Add catalyst aqueous solution 0.2% hypoiodous acid aqueous solution 5kg catalytic degradation 2 hours under heat preservation condition, 50 order gauze filter and form steady-state water-soluble active material solution, wherein the insoluble matter weight obtained by filtration is 0.15kg.
