Extraction method of auricularia auricula polysaccharides and preparing method of preparations of auricularia auricula polysaccharides

Abstract

The invention provides an extraction method of auricularia auricula polysaccharides and a preparing method of preparations of auricularia auricula polysaccharides and belongs to the field of biological medicine. The extraction method includes the steps of baking raw material of auricularia auricula, superfine grinding, extracting by adding water, and centrifuging to obtain auricularia auricula polysaccharides. Compared with the prior art, the yield and the .02- clearance rate of the auricularia auricula polysaccharides prepared according to the technical scheme are increased greatly.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a method for extracting polysaccharides from fungus and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the improvement of living standards, people's pursuit of high-quality life, health and comfort is becoming more and more intense. Fungal polysaccharides are currently the most promising new resource for health food and medicine. Scientific experiments have shown that fungal polysaccharides have anti-tumor activity, strong inhibitory effect on cancer cells, and play an important role in immune regulation, lowering blood pressure, lowering blood fat, and antithrombotic. At present, the research on the relationship between the structure, properties and pharmacodynamics of polysaccharides has become one of the most active research fields in life sciences. The main active ingredient in black fungus - black fungus polysacchar...

Problems solved by technology

Although the scientific research institutes of colleges and universities and many enterprises have carried out relevant research on the extraction of black fungus by using modern science and technology, they are all in the laboratory scale and stage, mainly because the black fungus extraction system is extremely viscous under normal circumstances, and the separation of material and liquid is difficult. , the extraction efficiency is extremely low, and it is difficult to achieve large-scale production; the difficulty in separating the material and liquid leads to a long extraction cycle, the loss or deterioration of active ingredients, and the existing black fungus extract related products are not only of poor quality, but also seriously adulterated

[0004] At present, the research methods for extracting black fungus polysaccharides mainly include: hot water extraction method, alkali extraction method, enzymatic method, ultrasonic-assisted extraction method, microwave-assisted extraction method, etc. Facilitates the dissolution of active ingredients

Using hot water to extract polysaccharides is a simple and easy method with low cost but low yield and time-consuming

Alkaline extraction of polysaccharides can shorten the time and increase the yield, but if the pH is too high, the biological activity of polysaccharides is easily lost

Enzymatic extraction uses cellulase, pectinase and neutral protease combined with hot water extraction. Although the yield of black fungus polysaccharides is high, the molecular structure of black fungus polysaccharides is destroyed, and the molecular weight of the extracted polysaccharides is greatly changed. Small, thus affecting the efficacy of black fungus polysaccharides
