Embodiment 1
[0052] The camel thorn sugar polymer was prepared according to the following steps:
[0053] 1) Material selection: Soak 30kg of the aboveground part of camel thorn in water for 12 hours;
[0054] 2) Water extraction: extract the aerial part of camel thorn soaked in step 1) with 10 times the volume of hot water (100°C) for 2 hours, and collect the extract;
[0055] 3) Fractional alcohol precipitation: Concentrate the extract obtained in step 2) at 60°C under reduced pressure, add ethanol for alcohol precipitation to make the volume concentration of ethanol 40%, leave it at room temperature for 24 hours, and then centrifuge to obtain supernatant 1 and precipitate 1, Collect the precipitate 1, which is the crude sugar polymer AP1; concentrate the supernatant 1 at 60°C under reduced pressure, add ethanol for alcohol precipitation to make the volume concentration of ethanol 60%, leave it at room temperature for 24 hours, and then centrifuge to obtain the supernatant 2 and precipit...
Embodiment 2
[0062] The camel thorn sugar polymer was prepared according to the following steps:
[0063] 1) Material selection: Soak 30kg of camel thorn in water for 6 hours;
[0064] 2) Water extraction: extract the aboveground part of camel thorn soaked in step 1) with 5 times the volume of hot water (60°C) for 3 hours, collect the extract and residue, and dry the residue;
[0065] 3) Fractional alcohol precipitation: Concentrate the extract obtained in step 2) at 40°C under reduced pressure, add ethanol for alcohol precipitation to make the volume concentration of ethanol 30%, leave it at room temperature for 10 hours, and then centrifuge to obtain supernatant 1 and precipitate 1, Collect the precipitate 1, which is the crude sugar polymer AP1; concentrate the supernatant 1 at 40°C under reduced pressure, add ethanol for alcohol precipitation to make the volume concentration of ethanol 60%, leave it at room temperature for 10 hours, and then centrifuge to obtain the supernatant 2 and p...
Embodiment 3
[0070] The camel thorn sugar polymer was prepared according to the following steps:
[0071] 1) Material selection: Soak 30kg of the aboveground part of camel thorn in water for 10 hours;
[0072] 2) Water extraction: extract the aboveground part of camel thorn soaked in step 1) with 15 times the volume of hot water (90°C) for 10 hours, collect the extract and residue, and dry the residue;
[0073] 3) Fractional alcohol precipitation: Concentrate the extract obtained in step 2) at 70°C under reduced pressure, add ethanol for alcohol precipitation so that the volume concentration of ethanol is 60%, leave it at room temperature for 28 hours, and then centrifuge to obtain supernatant 1 and precipitate 1, Collect the precipitate 1, which is the crude sugar polymer AP1; concentrate the supernatant 1 at 70°C under reduced pressure, add ethanol for alcohol precipitation to make the volume concentration of ethanol 80%, leave it at room temperature for 28 hours, and then centrifuge to ...
