Problems solved by technology

[0003] With the strict control of the use of sulfides in the raw material processing process in terms of food and drug safety, the traditional Gastrodia elata processing technology has been questioned
Especially the separation and preparation method of Gastrodia elata crude polysaccharide and Gastrodia elata alcohol solubles based on different effects has not been reported at present, so the separation and preparation method of Gastrodia elata crude polysaccharide and Gastrodia elata ethanol solubles with fresh gastrodia elata as raw material is a beneficial try

Embodiment 1

[0011] Wash 60kg of fresh Gastrodia elata and then use microwave method to kill green, and the heart of Gastrodia elata shall prevail;

[0012] Crush Gastrodia elata after killing green, add water to refine pulp, and perform centrifugal filtration twice in different ways, that is, coarse filtration with three-legged centrifuge and fine filtration with tubular centrifuge. Add 95% ethanol with three times the volume ratio to the supernatant under stirring, and statically precipitate Gastrodia elata The crude polysaccharide is filtered to take out the Gastrodia elata crude polysaccharide, dried and crushed under normal pressure and a temperature of 50°C to obtain Gastrodia elata crude polysaccharide powder;

[0013] The Gastrodia elata filter residue is percolated and extracted with the alcohol-water clear liquid after the polysaccharide is precipitated, and the extraction parameters of the gastrodia elata ethanol are: the ethanol concentration of the alcohol-water clear liquid is...

Embodiment 2

[0015] Wash the fresh Gastrodia elata and use the steaming method to complete the greening, and the heart of Gastrodia elata shall prevail;

[0016] Crush Gastrodia elata after killing green, add water to refine pulp, and perform centrifugal filtration twice in different ways, that is, coarse filtration with three-legged centrifuge and fine filtration with tubular centrifuge. Add 95% ethanol with three times the volume ratio to the supernatant under stirring, and statically precipitate Gastrodia elata The crude polysaccharide is filtered to take out the Gastrodia elata crude polysaccharide, dried and crushed under vacuum at a temperature of 65°C to obtain Gastrodia elata crude polysaccharide powder;

[0017] The Gastrodia elata filter residue is percolated and extracted with the alcohol-water clear liquid after the polysaccharide is precipitated, and the extraction parameters of the gastrodia elata ethanol are: the ethanol concentration of the alcohol-water clear liquid is 75%,...

Embodiment 3

[0019] Wash the fresh Gastrodia elata and use the microwave method to complete the greening, and the heart of Gastrodia elata shall prevail;

[0020] Crush Gastrodia elata after killing green, add water to refine pulp, and perform centrifugal filtration twice in different ways, that is, coarse filtration with three-legged centrifuge and fine filtration with tubular centrifuge. Add 95% ethanol with three times the volume ratio to the supernatant under stirring, and statically precipitate Gastrodia elata The crude polysaccharide is filtered to take out the Gastrodia elata crude polysaccharide, dried and crushed under vacuum at a temperature of 70°C to obtain Gastrodia elata crude polysaccharide powder;

[0021] The Gastrodia elata filter residue is percolated and extracted with the alcohol-water clear liquid after the polysaccharide is precipitated, and the extraction parameters of the gastrodia elata ethanol are: the ethanol concentration of the alcohol-water clear liquid is 72%...

Abstract

The invention relates to a method for separating and preparing Gastrodia elata crude polysaccharide and Gastrodia elata ethanol solubles using fresh gastrodia elata as raw materials. The technical scheme of the present invention is to clean the collected fresh Gastrodia elata and use microwave method or steaming method to de-enzyme, crush, add water to refine the slurry, use a three-legged centrifuge for coarse filtration and a tubular centrifuge for fine filtration, and the clear liquid is stirred. Add 95% ethanol with a volume ratio three times, statically precipitate Gastrodia elata crude polysaccharide, dry and crush to obtain Gastrodia elata crude polysaccharide powder; Gastrodia elata filter residue is percolated and extracted with alcohol and water after the polysaccharide is precipitated, and the extract is concentrated, dried, and crushed to obtain Gastrodia elata alcohol Soluble powder. The effect and use of the present invention can provide basic raw materials for health food with different curative effects and different functions of Gastrodia elata or single and prescription products of Chinese patent medicine. Under the premise of ensuring the efficacy of Gastrodia elata, it has the advantages of less dosage and easy absorption, ensuring the function of Gastrodia elata The play of Tianma has improved the physiological effects of Gastrodia elata on the human body.

Description

technical field [0001] The invention relates to a method for separating and preparing Gastrodia elata crude polysaccharides and Gastrodia elata ethanol solubles using fresh Gastrodia elata as raw materials, and belongs to the field of extraction and processing of plant active ingredients. technical background [0002] Gastrodia elata, as a precious traditional Chinese medicine raw material, has sedative effects, anticonvulsant effects, analgesic effects, anti-inflammatory effects, anti-aging effects on cells, and effects on the high-level nervous center and cardiovascular system. It has been confirmed by modern pharmacology research and has remarkable efficacy. , has been widely used in modern medical clinics, such as Gastrodia elata buccal tablets, Gastrodia elata wine, Gastrodia elata royal jelly, Gastrodia elata capsules and other products. However, the raw materials used in these products mostly rely on the traditional gastrodia elata raw material processing technology, ...
