Embodiment 1

[0023] A method for extracting natural bamboo juice polysaccharides, comprising the steps of:

[0024] (1) Juice extraction: From 20:00 every night to 06:00 the next morning, from the green bamboo in Guangxi [Taiwan Sweet Bamboo, Dendrocalamopsis oldhami (Munro) Keng f.] from natural bamboo juice.

[0025] (2) Impurity removal and preservation: quickly filter the obtained bamboo juice to remove insoluble impurities, then put the obtained bamboo juice into a sterilized food-grade plastic container, and place it in a refrigerator at 0-4°C for later use.

[0026] (3) Concentration at low temperature: Put 2000mL of bamboo juice in a rotary evaporator, and concentrate it to 50mL under a negative pressure of 0.1MPa and a low temperature of 50°C to obtain a concentrated solution.

[0027] (4) Ethanol precipitation: Mix the concentrated solution and ethanol evenly at a volume ratio of 1:8, then let it stand for 2 hours to settle, wait for the precipitation to separate out, and carry...

Embodiment 2

[0036] A method for extracting natural bamboo juice polysaccharides, comprising the steps of:

[0037] (1) Juice extraction: From 20:00 every night to 06:00 the next morning, from the green bamboo in Guangxi [Taiwan Sweet Bamboo, Dendrocalamopsis oldhami (Munro) Keng f.] from natural bamboo juice.

[0038] (2) Impurity removal and preservation: quickly filter the obtained bamboo juice to remove insoluble impurities, then put the obtained bamboo juice into a sterilized food-grade plastic container, and place it in a refrigerator at 0-4°C for later use.

[0039] (3) Concentration at low temperature: put the bamboo juice in a rotary evaporator, and concentrate it at a negative pressure of 0.15MPa and a low temperature of 40°C to obtain a 40-fold concentrated solution.

[0040] (4) Ethanol precipitation: Mix the concentrated solution and ethanol evenly at a volume ratio of 1:8, and then set aside to settle for 2 hours. After the precipitation is separated, perform centrifugation, ...

Embodiment 3

[0049] A method for extracting natural bamboo juice polysaccharides, comprising the steps of:

[0050] (1) Juice extraction: From 20:00 every night to 06:00 the next morning, from the green bamboo in Guangxi [Taiwan Sweet Bamboo, Dendrocalamopsis oldhami (Munro) Keng f.] from natural bamboo juice.

[0051] (2) Impurity removal and preservation: quickly filter the obtained bamboo juice to remove insoluble impurities, then put the obtained bamboo juice into a sterilized food-grade plastic container, and place it in a refrigerator at 0-4°C for later use.

[0052] (3) Concentration at low temperature: put the bamboo juice in a rotary evaporator, and concentrate it at a negative pressure of 0.05MPa and a low temperature of 60°C to obtain a 40-fold concentrated solution.

[0053] (4) Ethanol precipitation: mix the concentrated solution and ethanol evenly at a volume ratio of 1:8, and then set aside to settle for 3 hours. After the precipitation is separated, carry out centrifugati...

Abstract

The invention discloses an extraction method of natural bamboo juice polysaccharides. The extraction method includes the steps of juice selection, impurity removing and preservation, low-temperature concentration, ethanol precipitation, protein removing, secondary alcohol precipitation, drying and the like. By the extraction method, the extracted bamboo juice polysaccharides are high in purity, the purity of the polysaccharides reaches 80-85%, the high-purity soluble polysaccharides are stable in quality, the original immune function enhancing effect of the polysaccharides is kept, and the obtained bamboo juice polysaccharides has potential effects of strengthening the physique and healthcare.

Description

technical field [0001] The invention relates to the technical field of deep processing of ethnic medicinal materials, in particular to a method for extracting natural bamboo juice polysaccharides. Background technique [0002] Bamboo juice is the water of life and living water. It is filtered, purified and activated by the bamboo itself. It is very pure and contains rich nutrients and biological enzymes. It is used for detoxification and hangover, relieving cough and phlegm, sore mouth and tongue, cough and shortness of breath, clearing heart and irritability, vomiting during pregnancy, gastrointestinal ulcer, chest pain, fullness in chest cavity, refreshing spleen and appetizing, and children's wind-heat shock and pain. Anti-cancer and anti-cancer effects. Chinese and foreign scientists have shown that bamboo juice contains a variety of precious trace elements, such as silicon, zinc, selenium, germanium, iron and more than 20 kinds of trace elements and calcium, phosphorus...
