Embodiment 1

[0027] Embodiment 1 Get dry highland barley seedling raw material 10Kg, cut into the small section of 1~2cm or pulverize into coarse powder, use 10 times of raw material weight amount, the ethanol solution that concentration is 10%, at temperature 70 ℃, use Wuhan Huipeng pharmaceutical machinery The TQ-300 small multi-functional extraction unit produced by Equipment Co., Ltd. extracts 1 to 4 times, each time for 0.5 to 4 hours, and the extract is obtained after filtering and sedimenting through the bottom screen of the extraction tank of the multi-functional extraction unit; The SHB-C vacuum pump produced by the limited company pumps air and reduces pressure, recovers the ethanol in the extract until the alcohol concentration is less than 5%, and obtains a concentrated solution of 30Kg.

[0028] After diluting the concentrated solution with 2 times the amount of 60Kg pure water, use the GQ75 tubular centrifuge produced by Shanghai Pudong Tianben Centrifugal Machinery Co., Ltd. ...

Embodiment 2

[0033] Embodiment 2 Get dry highland barley seedling raw material 10Kg, be cut into the subsection of 1~2cm or be pulverized into coarse powder, use the ethanol solution that 20 times of raw material weight, concentration are 60%, use small-scale multifunctional extraction unit at temperature 80 ℃ Extract 1 to 4 times, each time for 0.5 to 4 hours, and obtain the extract after filtering the precipitate through the bottom screen of the extraction tank of the multifunctional extraction unit; After the concentration is less than 5%, 25Kg of concentrated solution is obtained.

[0034] After the concentrated solution is diluted with 2 times the amount of 50Kg pure water, it is centrifuged at a speed of 20000 rpm with a GQ75 type tubular centrifuge to remove suspended particulate impurities such as dust to obtain 75Kg of the centrifuge.

[0035] The centrifugate was filtered with a SJM-FHM-10 type 100nm ceramic microfiltration membrane device to obtain 100Kg of clarified liquid (40K...

Embodiment 3

[0039] Embodiment 3 Get dry highland barley seedling raw material 10Kg, cut into the segment of 1~2cm or pulverize into coarse powder, use 25 times of raw material weight amount, concentration be the ethanol solution of 40%, use TQ-300 small multi-purpose at temperature 90 ℃. The functional extraction unit extracts 1 to 4 times, each time for 0.5 to 4 hours, and the extract is obtained after filtering and sedimenting through the bottom screen of the extraction tank of the multifunctional extraction unit; After ethanol reaches the concentration of alcohol < 5%, 28Kg of concentrated solution is obtained.

[0040] After the concentrated solution is diluted with 2 times the amount of 56Kg pure water, it is centrifuged at a speed of 20000 rpm with a GQ75 type tubular centrifuge to remove suspended particulate impurities such as dust to obtain 83Kg of the centrifuge.

[0041]The centrifugal liquid adopts SJM-FHM-10 type 50nm ceramic microfiltration membrane equipment to filter, and ...

Abstract

The invention relates to a novel process for preparing highland barley flavone extract, comprising the following steps of extracting flavonoids form highland barley seedlings by a normal hydrous alcohol solvent reflux extraction method; removing particular impurities such as dusts by a tubular centrifuge; carrying out the procedures of filtering for clarification through a ceramic membrane, interception for separation through anultrfiltration membrane, desalination for concentration through a nanofiltration membrane and the like; and finally drying by spraying or microwave to obtain the highland barley flavone extract containing 8.1-14.9 percent of total flavone . Meanwhile, the invention also discloses the application of the highland barley flavone extract prepared by the process in health wine. In the invention, purification and separation are carried out in a combined membrane separation mode, so that the invention has the advantages of good separation effect, high yield of effective substances and good stability of the product.

Description

technical field [0001] The invention relates to a new preparation process of highland barley flavone extract and its application in health-care wine. Background technique [0002] Highland barley (Hordeum vulgare L.var.nudum Hook.f.) is a cereal crop of the genus Hordeumvulgare in the Gramineae family. It is also called bare barley, rice barley, and barley because of the separation of the inner and outer glumes and the naked grain. . Highland barley has rich nutritional value and outstanding medical and health care functions. According to the "Supplements to Materia Medica": Highland barley, the lower Qi is wide and medium, strong and lean, dehumidifying and sweating, and antidiarrheal. Tibetan medicine classics "Jingzhu Materia Medica" even uses highland barley as an important medicine to treat various diseases. [0003] In recent years, research on the development of highland barley has mainly focused on the functional component β-glucan in seeds, and there are relative...
