Embodiment 1
[0031] Preparation of Cigu polysaccharide: After removing impurities, washing and slicing fresh Cigu, immediately add water with a mass-to-volume ratio of 1:10 (g:mL) to make a slurry. The slurry is passed through a 60 mesh industrial filter cloth to obtain a filtrate. The filtrate is subjected to pressure The pump is injected into the subcritical extraction kettle, the magnetic coupling stirrer is controlled to 300 revolutions / min, the extraction pressure is 1MPa, the temperature is 100 ℃, and the extraction is 10 minutes. After the end, centrifuge and collect the supernatant; concentrate the supernatant to 1 / 2 of the original volume ; Add 4 times its volume of 95% ethanol to the concentrated solution, leave it for 24 hours, and centrifuge to separate the precipitate; after the precipitate is reconstituted, the DEAE-52 cellulose that has been balanced on it, first eluted with deionized water, and then It is eluted with 0.1% NaCl solution with mass fraction, and the salt eluate ...

[0034] Preparation of Cigu polysaccharide: After removing impurities, washing and slicing fresh Cigu, immediately add water with a mass-to-volume ratio of 1:10 (g:mL) to make a slurry. The slurry is passed through a 60 mesh industrial filter cloth to obtain a filtrate. The filtrate is subjected to pressure The pump is injected into the subcritical extraction kettle, the magnetic coupling stirrer is controlled at 450 rpm, the extraction pressure is 6 MPa, the temperature is 140 ℃, and the extraction is 10-30 min. After the end, centrifuge and collect the supernatant; the supernatant is concentrated to 1 of the original volume / 2; Add 4 times its volume of 95% ethanol to the concentrated solution, leave it to stand for 24 hours, and centrifuge to separate the precipitate; after the precipitate is re-dissolved, the DEAE-52 cellulose that has been balanced on it, first eluted with deionized water , And then eluted with 0.1% NaCl solution with mass fraction, collected the salt eluate...

[0037] Preparation of Cigu polysaccharide: After removing impurities, cleaning and slicing fresh Cigu, immediately add water with a mass-to-volume ratio of 1:10 (g:mL) to make a slurry. The slurry is passed through a 60 mesh industrial filter cloth to obtain a filtrate. The filtrate is passed through a pressure pump Inject into the subcritical extraction kettle, control the magnetic coupling stirrer at 600 rpm, the extraction pressure is 12MPa, the temperature is 180°C, and the extraction is 30min. After the end, centrifuge and collect the supernatant; concentrate the supernatant to 1 / 2 of the original volume; Add 4 times the volume of 95% ethanol to the concentrated solution. After standing for 24 hours, the precipitate is separated by centrifugation; after the precipitate is re-dissolved, the DEAE-52 cellulose that has been balanced is loaded, first eluted with deionized water, and then used The mass fraction of 0.1% NaCl solution is eluted, and the salt eluate is collected an...
