Ultrasonic Extraction of polysaccharides is the use of ultrasonic waves to produce high speed, strong cavitation effect and stirring effect, which makes the cell wall of traditional Chinese medicine plants easy to break, and is conducive to the dissolution of polysaccharide.To improve the extraction effective.

Extracting Processing :

1. Pre-treatment: Clean fresh mushrooms, remove impurities such as roots and inedible parts, and then slice or crush them.
2. Ultrasonic assisted extraction: The pulverized mushroom powder is mixed with water in a certain proportion, and the ultrasonic assisted extraction equipment is used to extract at a set temperature (such as 60 ° C) and time (such as 30 minutes). The cavitation effect of ultrasonic waves helps to break down the cell walls of mushrooms and release polysaccharides.

3. Centrifugal separation: After ultrasonic extraction, the solid residue in the extraction liquid is separated by centrifugation.

4. Alcohol precipitation: Add an appropriate amount of ethanol or other organic solvents to the extraction solution after centrifugation for precipitation, and the polysaccharide is insoluble in ethanol, so that it can be separated by precipitation.

5. Washing: The precipitated polysaccharide is repeatedly washed by solvents such as ethanol, acetone or ether to remove impurities such as protein and pigment.

6. Drying: The washed polysaccharide is dried by freeze-drying or spray drying and other methods to obtain polysaccharide powder.
