Embodiment 1

[0025] see figure 1 Shown process flow diagram, a kind of polysaccharide extracting method of Fructus agaricus of the present invention, comprises the following steps:

[0026] (1) Drying: Take 100kg of sand garden seeds and put them into the drying device at a temperature of 50°C, and dry them until they are brittle.

[0027] (2) Crush and sieve: crush and sieve the dried sand garden seeds with a mesh number of 30 mesh.

[0028] (3) Petroleum ether degreasing: The pulverized Shayuanzi is degreased with petroleum ether for 3 times by continuous extraction method, and refluxed until the petroleum ether extract is colorless.

[0029] (4) Ultrasonic extraction: The degreased Shayuanzi is extracted by ultrasonic method, the ratio of solid to liquid is 1:10, and the extraction time is 20 minutes.

[0030] (5) Centrifugal filtration: Centrifuge the leached sand garden seeds at 1500r / min, and filter.

[0031] (6) Vacuum concentration: take the filtrate and carry out vacuum concent...

Embodiment 2

[0038] see figure 1 Shown process flow diagram, a kind of polysaccharide extracting method of Fructus agaricus of the present invention, comprises the following steps:

[0039] (1) Drying: Take 50kg of sand garden seeds and put them in a drying device at a temperature of 55°C, and dry them until they are brittle.

[0040] (2) Crush and sieve: crush and sieve the dried sand garden seeds with a mesh number of 30 mesh.

[0041] (3) Petroleum ether degreasing: The pulverized Shayuanzi is degreased twice with petroleum ether by continuous extraction method, and refluxed until the petroleum ether extract is colorless.

[0042] (4) Ultrasonic extraction: The degreased sand garden seeds are extracted by ultrasonic method, the ratio of solid to liquid is 1:10, and the extraction time is 15 minutes.

[0043] (5) Centrifugal filtration: Centrifuge the leached sand garden seeds at 1500r / min, and filter.

[0044] (6) Vacuum concentration: take the filtrate and carry out vacuum concentra...

Abstract

The invention discloses a method for extracting a polysaccharide from flatstem milkvetch seeds. The method comprises the steps of drying and crushing the flatstem milkvetch seeds as a raw material, carrying out degreasing treatment by using petroleum ether, carrying out ultrasonic extraction on degreased flatstem milkvetch seed crude powder and centrifugally filtering taken extraction solution to obtain a filtrate; carrying out vacuum concentration on the filtrate, separating and precipitating the obtained concentrate by using absolute ethyl alcohol and sequentially carrying out micro-filtration membrane filtration, ultrafiltration membrane concentration and organic membrane decoloration to obtain a polysaccharide concentrate; and carrying out vacuum drying on the polysaccharide concentrate to prepare a polysaccharide product. The process for extracting the polysaccharide from the flatstem milkvetch seeds is simple in operation, good in extraction stability, low in operation cost and low in pollution, and the obtained polysaccharide product is good in quality.

Description

technical field [0001] The invention belongs to the technical field of preparation of functional sugars, and in particular relates to a method for extracting polysaccharides from Azalea fruticosa. Background technique [0002] Azalea is a precious traditional Chinese medicinal material, which can be used to treat symptoms such as liver and kidney weakness, sore waist and knees, frequent urination, and blurred vision. In terms of the biological activity research of its medicinal monomers, there are more studies on the flavonoids of Fructus Fructus Fructus, but less research on the extraction of Fructus Fructus polysaccharides. Current studies have shown that polysaccharides have good biological activity and can enhance human immunity, and have been used in the treatment of AIDS, hepatitis and other intractable diseases. With the development of chemical synthesis and separation, pharmaceutical purification and membrane technology The continuous development of polysaccharide d...
