Method with ultra-high pressure for extracting ganoderma lucidum polysaccharide in glossy ganoderma

Abstract

The purpose of the present invention is to overcome the disadvantages of relatively low extraction rate and low extraction purity of conventional techniques, and provide a method for extracting polysaccharides from Ganoderma lucidum by using ultra-high pressure technology. The application of ultra-high pressure technology in the present invention is a treatment method that applies a pressure greater than 100 hydrostatic pressure to the raw material under normal temperature and near normal temperature conditions. The ultra-high pressure can make the solvent enter the interior of the plant cells, and the solvent can carry the active ingredient after the pressure is released. And overflow, to achieve high extraction efficiency of plant active ingredients, use macroporous resin to adsorb and purify Ganoderma lucidum polysaccharides, good adsorption selectivity to Ganoderma lucidum polysaccharides, fast adsorption and resolution, and large adsorption capacity.

Description

Technical field:

[0001] The invention belongs to the field of natural organic chemistry and relates to a purification method of ganoderma lucidum polysaccharides, in particular to a method for extracting ganoderma lucidum polysaccharides from ganoderma lucidum by ultra-high pressure technology. Background technique:

[0002] Ganoderma lucidum, also known as Lingzhi, grows best in the forest and has the highest medicinal effect. At present, there are also artificial greenhouses for cultivation, mainly growing in humid places. Ganoderma lucidum is a high-temperature fungus, which can grow between 15-35°C, and the optimum temperature is 25-30°C. Fruiting bodies can grow in the range of 10-32°C, but the optimum temperature for primordium differentiation and fruiting body development is 25-28°C. Below 25°C, the fruiting body grows slowly and the color of the shell is poor; above 35°C, the fruiting body will die. Ganoderma lucidum needs high humidity to grow. With the increase...
