Problems solved by technology

However, the operation of the ultrasonic-assisted compound enzyme method is cumbersome, and the strong shear force of the ultrasonic wave may destroy the structure of the polysaccharide, and the enzyme is a protein whose reaction conditions are very strict, and it is easy to deteriorate and lose its activity. The dissolved quality is unstable, so that the extraction yield of polysaccharides is fluctuated

Abstract

The invention discloses a preparation method of phellinus linteus polysaccharides. The preparation method comprises the following steps: (1) removing impurities from wild phellinus linteus and crushing the wild phellinus linteus; (2) freezing phellinus linteus in the step (1) to obtain freeze-dried powder; (3) breaking the wall of the freeze-dried powder obtained in step (2) in a low temperature environment to obtain phellinus linteus powder; (4) adding water to the phellinus linteus powder treated in the step (3) for leaching, taking a filtrate, and performing concentration under reduced pressure to obtain a water extract; (5) adding a mixture of ethanol, n-butanol and methanol to the water extract of the step (4) to obtain a precipitate; (6) washing the precipitate with an organic solvent and drying the precipitate to obtain the phellinus linteus polysaccharides. The preparation method of the phellinus linteus polysaccharides has the advantages that on the premise of maintaining activity of the phellinus linteus polysaccharides, the content and purity of the phellinus linteus polysaccharides are increased, and the medicinal value of the phellinus linteus polysaccharides is further improved.

Description

technical field [0001] The invention relates to an extraction method of natural products, in particular to an extraction method of Phellinus polysaccharide. Background technique [0002] Phellinus polysaccharide is an active substance existing in Phellinus chinensis, and it is a helical three-dimensional structure. Therefore, the current technology for extracting and purifying Phellinus polysaccharide is water extraction and alcohol precipitation method, that is, using a large amount of water to boil and reflux The raw material of Phellinus Phellinus was cooked for a long time to dissolve Phellinus polysaccharides from the cells, then add ethanol to precipitate the polysaccharides, and then filter to obtain Phellinus polysaccharides. Although Phellinus polysaccharides can be extracted from Phellinus polysaccharides by high temperature and high pressure treatment, the dissolution rate of Phellinus polysaccharides can be improved, and the recovery rate of polysaccharides can b...
