Abstract

An edible and medicinal fungal polysaccharide low-temperature normal-pressure plasma extraction method includes the first step of adsorption resin preprocessing, the second step of fungal polysaccharide primary extraction, the third step of low-temperature normal-pressure plasma extraction, the fourth step of porous adsorption resin extraction, the fifth step of alcohol precipitation and the sixth step of drying. The fungal polysaccharide prepared through extraction is prepared from lentinula edodes, hericium erinaceus, ganoderma lucidum, black fungi, grifola frondosa, white fungi, flammulina velutipes and any one or combination of edible and medicinal fungi containing polysaccharide compounds. According to the edible and medicinal fungal polysaccharide low-temperature normal-pressure plasma extraction method, the extraction period is shortened, the use amount of solvents is small, production efficiency is high, energy is saved, consumption is reduced, and extraction purity is high.

Description

technical field [0001] The invention relates to a method for extracting active ingredients in edible and medicinal fungi, in particular to a method for extracting polysaccharides from edible and medicinal fungi with low temperature and normal pressure plasma. Background technique [0002] Edible and medicinal fungal polysaccharides generally refer to high molecular polymers separated from the fruiting body, mycelium, and fermentation broth of edible and medicinal fungi, consisting of more than 10 monosaccharide units. Internationally, edible and medicinal fungal polysaccharides are called "biological response modifiers" (Biological Response Modifier, referred to as BRM). Modern pharmacological research shows that it is a class of biological functions such as anti-infection, anti-radiation, anti-coagulation, hypoglycemia, prevention and treatment of tumors, anti-fatigue, etc. It is an important natural medicinal active ingredient and health food. In recent years, with the em...
