Embodiment 1
[0040]Take an appropriate amount of dried and crushed coriander root, heat it to reflux with 5 times the amount of distilled water, and extract 3 times. The extraction time is 3, 2 and 1 hour respectively. The three extracts are combined and filtered with a 150-mesh double-layer filter cloth. The filtrate is at 70°C. Use thin film evaporation to concentrate to 1 / 3 of the original volume; under stirring, add 5 times 75% ethanol to the concentrated extract to precipitate the polysaccharide in the concentrated extract, and collect the polysaccharide crude precipitate of Daphne root polysaccharide; to the crude polysaccharide precipitation Add distilled water to dissolve it to make it fully reconstituted. Use the sevag method to remove the protein. Repeat for 9 times and concentrate (the method is the same as above). Add 5 times 75% methanol to the concentrated solution for alcohol precipitation, precipitation with absolute ethanol, Wash with acetone and diethyl ether to obtain the de...
Embodiment 2
[0044] Take an appropriate amount of dried and crushed coriander root, heat it to reflux with 20 times the amount of distilled water, and extract 4 times. The extraction time is 3, 2 and 1 hour respectively. The three extracts are combined and filtered with a 100 mesh double-layer filter cloth. The filtrate is at 50°C. Use thin film evaporation to concentrate to 1 / 5 of the original volume; under stirring, add 2 times 95% ethanol to the concentrated extract to precipitate the polysaccharide in the concentrated extract, and collect the polysaccharide crude precipitate of Daphne root polysaccharide; to the crude polysaccharide precipitation Add distilled water to dissolve it to make it fully reconstituted, remove protein by sevag method, repeat 3 times, concentrate (the method is the same as above), add 3 times 85% methanol to the concentrated solution for alcohol precipitation, precipitation with absolute ethanol, Wash with acetone and ether to obtain the deproteinized polysaccharid...
Embodiment 3
[0048] Take an appropriate amount of dried and crushed coriander root and soak it in 5 times the amount of distilled water for 2 hours. Under the processing conditions of microwave power of 600W, material-to-liquid weight ratio of 1:5, and microwave extraction time of 2 minutes, the residue is added after one microwave extraction Soak the same volume of water for another 1 hour, and then extract twice by microwave; combine the two extracts, filter with 150 mesh double-layer filter cloth, and concentrate the filtrate under reduced pressure at 70℃ to 1 / 3 of the original volume; concentrate the extract under stirring Add 5 times 75% ethanol to the concentrated extract to precipitate out the polysaccharides in the concentrated extract, and collect the crude polysaccharides of Daphne root polysaccharides; add distilled water to the crude polysaccharides to dissolve them and make them fully reconstituted. Use the sevag method to remove the protein. Repeat Perform 9 times, concentrate (t...
