Separation preparation method of gastrodia elata crude polysaccharide and gastrodia elata alcohol extract using fresh gastrodia elata as raw material

Abstract

The invention relates to a separation and preparation method of crude polysaccharide of gastrodia tuber which takes fresh gastrodia tuber as the raw material and a gastrodia tuber alcohol-soluble substance. The technical scheme of the invention is characterized in that the collected fresh gastrodia tuber is washed, deactivated to remove enzymes by a microwave method or a cooling process, crashed and pulped into pulp with water, and the pulp is roughly filtered by a three-column centrifuge and finely filtered by a tubular centrifuge to obtain a clear solution, which is added with 95% ethanol 3 times the volume of the clear solution while being stirred and kept standing to precipitate the crude polysaccharide of the gastrodia tuber; the crude polysaccharide is dried and crashed to obtain crude polysaccharide powder of the gastrodia tuber; diacolation extraction is carried out on the filter residue of the gastrodia tuber by the ethanol-water clear solution which is used for precipitating the polysaccharide so as to obtain an extracting solution, and the extracting solution is condensed, dried and crashed to obtain the gastrodia tuber alcohol-soluble powder. The effect and use of the crude polysaccharide of the gastrodia tuber can provide a base material for single and compound Chinese patent medicine products or healthcare foods which are made of the gastrodia tuber and have different treatment effects and different actions. The crude polysaccharide of the gastrodia tuber has the advantages of low amount requirement and easy absorption in the precondition that efficacies of the gastrodia tuber are guaranteed, thus ensuring effects of the gastrodia tuber and improving the physiological effects of the gastrodia tuber on 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, ...

AI Technical Summary

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
