preparation example Construction

[0029] The preparation method of seaweed sulfated polysaccharide of the present invention comprises the following steps:

[0030] S10. Put the kelp in water with a mass of 38-42 times its own mass and soak it for 35-45 minutes, then rinse it with water with an amount of 38-42 times its own mass;

[0031] S20. Pretreat the kelp, remove the unqualified kelp with yellow leaves, broken leaves and moldy, and cut the qualified kelp into pieces with an area of ​​7-10 square centimeters; since the kelp is in the shape of a long strip, it is suitable to be cut into pieces by chopping Helps improve efficiency and productivity.

[0032] S30. Add kelp to water 9-11 times its own weight and decoct three times, respectively for 1.9-2.1 hours, 1.4-1.6 hours, and 1.4-1.6 hours; extracting seaweed sulfated polysaccharides in kelp by decocting can More fully extract the sulfated polysaccharides from seaweed in kelp.

[0033] S40. Combining the three decoction liquids and concentrating under r...

Abstract

The invention discloses a preparation method for sulfated polysaccharides from seaweed. The sulfated polysaccharides from seaweed are prepared from sea-tangle through pretreatment, two-step water extraction, two-step alcohol precipitation, one-step alcohol dissolving and drying. The preparation method can effectively extract the seaweed sulfated polysaccharides in the sea-tangle and is capable of improving efficiency and yield of the seaweed sulfated polysaccharides through elaborate designing of every technological parameter.

Description

technical field [0001] The invention relates to a method for extracting medicines, in particular to a preparation method for seaweed sulfated polysaccharide. Background technique [0002] Different from the production process of similar varieties that have been chemically modified or processed, the preparation method of seaweed sulfated polysaccharide adopts natural bioactive technology. In the process of extraction, separation and purification, no precipitants and organic reagents such as lead hydroxide, calcium chloride, quaternary ammonium salt, ether, acetone are added, and no acid-base processing or sulfonation chemical modification is required. A preparation medium. This process neither destroys the natural chemical composition of the effective part, but also avoids the pollution caused by the extraction and purification process and the adverse effects of strong acid and strong alkali on the drug. [0003] While extracting the effective components of sulfated polysac...
