Problems solved by technology

[0005] The purpose of the present invention is to provide a method for extracting Phellinus polysaccharides, which overcomes the changes in the structure of polysaccharides caused by the use of high temperature and high pressure for a long time in the prior art to reduce the activity, and the use of ultrasonic and enzymatic hydrolysis processes makes the yield of polysaccharides unstable. high cost

Embodiment 1

[0016] Grinding the dried Phellinus Phellinus with an ordinary pulverizer, passing through a 40-mesh sieve, adding the Phellinus Phellinus coarse powder passed through the 40-mesh sieve into a high-energy nano-impact mill, and pulverizing to obtain Phellinus Phellinus nano-powder with an average particle size of 100-500 nanometers;

[0017] Add 10kg Phellinus nanopowder into the extraction tank, leaching with 150kg water at 80°C with stirring for 90min, cool to room temperature, filter, and the filtrate is Phellinus polysaccharide solution.

Embodiment 2

[0019] Grinding the dried Phellinus Phellinus with an ordinary pulverizer, passing through a 40-mesh sieve, adding the Phellinus Phellinus coarse powder passed through the 40-mesh sieve into a high-energy nano-impact mill, and pulverizing to obtain Phellinus Phellinus nano-powder with an average particle size of 100-500 nanometers;

[0020] Add 10kg Phellinus nanopowder into the extraction tank, leaching with 200kg water for 30min under stirring at 100°C, cool to room temperature, filter, and the filtrate is Phellinus polysaccharide solution.

Embodiment 3

[0022] Grinding the dried Phellinus Phellinus with an ordinary pulverizer, passing through a 40-mesh sieve, adding the Phellinus Phellinus coarse powder passed through the 40-mesh sieve into a high-energy nano-impact mill, and pulverizing to obtain Phellinus Phellinus nano-powder with an average particle size of 100-500 nanometers;

[0023] Add 10kg Phellinus nanopowder into the extraction tank, leaching with 160kg water at 90°C for 60min with stirring, cool to room temperature, filter, and the filtrate is Phellinus polysaccharide solution.

[0024] Phellinus polysaccharide content was determined by phenol-sulfuric acid method, and the theoretical polysaccharide content in Phellinus raw material was 2.18%, that is, 1kg Phellinus contained 21.8 grams of polysaccharide.

[0025] Thermal extraction method 1 refers to that Phellinus Phellinus is crushed with an ordinary pulverizer and passed through a 40-mesh sieve, adding water 20 times the weight of Phellinus Phellinus, extractin...

Abstract

The invention provides a method of extracting Phellinus igniarius polysaccharides, and the method is characterized by comprising: crushing the dried Phellinus igniarius with a grinder, sieving with a 40-mesh screen, placing into a high-energy nano impact mill for pulverization, and obtaining Phellinus igniarius nano powder with an average particle size of 100-500 nm; and then, extracting for 30 ~ 90min at a temperature of 80-100 DEG C by using water with a weight of 15-20 times of that of the Phellinus igniarius, cooling to the room temperature and filtering to give a Phellinus igniarius polysaccharide solution. According to the method of extracting Phellinus igniarius polysaccharides of the invention, the extraction temperature is low and the extraction time is short, thereby preventing damage of the Phellinus igniarius polysaccharide molecular structure, and maintaining the biological activity of polysaccharides.

Description

technical field [0001] The invention relates to a method for extracting Phellinus polysaccharides, which belongs to the field of plant active ingredient extraction. Background technique [0002] Phellinus igniarius (L.: Fr.) Quél. Chinese aliases Phellinus igniarius, Phellinus igniarius, Sang Ganoderma lucidum. It is recorded in Chinese medicine books that Phellinus has the effects of benefiting the five internal organs, softening the firmness, detoxifying, stopping bleeding, promoting blood circulation, harmonizing the stomach and relieving diarrhea. The triterpenoids, polysaccharides and flavonoids in Phellinus Phellinus are the active components of Phellinus Phellinus, among which polysaccharides are the main ones. Phellinus polysaccharides can improve the body's immunity, accelerate blood microcirculation, improve blood oxygen supply capacity, reduce the body's ineffective oxygen consumption in a static state, eliminate free radicals in the body, improve the sealing deg...
