Example Embodiment

[0007] An example is given below to further illustrate the present invention:

[0008] Crush the dried tubers of Bletilla striata tuber from the orchid family and pass through a 20-mesh sieve. Take 100 g of the sieved solid, add 550 g of deionized water, stir, temperature 72 ℃, dissolution time 2.5 hours, centrifugal precipitation, rotation speed 3000 rpm, centrifuge After 10-15 minutes, remove the insoluble matter to obtain a clear viscous solution, flocculate, 100ml of the solution obtained by centrifugation, add 200ml of 95% ethanol to form a white flocculent precipitate, stand overnight, filter, and dry at 50-60 ℃ to obtain Bletilla striata polysaccharide coarse powder.

Abstract

The invention relates to a method for applying bletilla striata polysaccharide to a hemostatic material. In the prior art, the hemostatic material is used by directly grinding bletilla tuber into powder, so that the method has the disadvantages of much impurity, incapability of controlling the effective content and inconvenience for use. According to the method disclosed by the invention, orchid, namely a dry bletilla tuber product, is dissolved and extracted by adding water and precipitated and dried by using ethanol to form coarse powder; the method has the advantages of non-complex extraction method, low cost, high effective content, less impurity and good hemostatic effect; after being processed, the coarse powder can be made into products, such as a sponge type material, a hemostatic tooth plug and the like; and the method is widely applied to medicine and biomedical engineering.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to a method for using bletilla striata polysaccharides in hemostatic materials. Background technique [0002] The hemostatic material used in the prior art is to directly grind the dry tuber of the orchid plant Bletilla striata into powder for use. The disadvantage is that it does not add extraction, the content of impurities is large, the content of effective substances cannot be controlled, and it is inconvenient to use. Up to now, there is still no A method for extracting effective polysaccharides from bletilla striata tubers. Contents of the invention [0003] The invention aims at the deficiencies in the prior art, and provides a method for using bletilla striata polysaccharide as a hemostatic material. [0004] The object of the present invention can be achieved through the following measures: the extraction method of the hemostatic material Bletilla striata po...
