Embodiment 1

[0013] This embodiment is suitable for industrialized production. The extraction method starts from the cultivation of the golden ear fungus until finally obtaining the golden ear polysaccharide. The specific process steps include: A', cultivation 1), bacterial strain cultivation——add water to the potato, and the ratio is 100g potato: 1000ml

[0014] Water, boiled and filtered; add sugar and agar to the filtrate, the ratio is 1000ml

[0015] Filtrate: 20g sugar: 18g agar; sterilize after dispensing into test tubes, then cool and put

[0016] into a slanted surface; insert golden ear bacteria at room temperature, cultivate for a week, and place in the refrigerator to form

[0017] Cook for one month; 2), wheat bran strains - add water to the wheat bran, the ratio is 150g wheat bran: 100ml, stir

[0018] Uniform; Divided into Erlenmeyer flasks for sterilization and cooling; Insert the bacteria in the test tube

[0019] 3), seed tank...

Abstract

The present invention relates to a method for extracting main component from tremella mesentarica fungus, belonging to the field of health-care food and medicine technology. The said method includes the steps of separating mycellia in a tank, cooking mycellia, using strong alkali to hydrolyze cooking liquor, centrifugal separating hydrolysate, ultrafiltering, concentrating ultrafiltrate by uisng alcohol and crystallizing, and the said invention provides the method for extracting tremella mesentarica polysaccharide. The said method is simple and easy to implement industrial development.

Description

technical field [0001] The invention relates to a method for extracting effective components in fungi, in particular to a method for extracting main components in auricularia fungus, and belongs to the technical fields of health food and medicine. Background technique [0002] Golden ear is a famous edible and medicinal fungus in Basidiomycetes and Tremellaceae, mainly produced in the deep mountains of my country's Yunnan, Guizhou and other places. According to "Compendium of Materia Medica" records: golden ear can cure "accumulation of addiction to drink, abdominal pain and gold sore". Its nature and flavor effects have been recorded in the literature as "warm in the middle and cold, sweet in taste, can reduce phlegm, stop phlegm, calm asthma, regulate qi, calm liver yang". "Chinese Medicinal Mycology" literature reports that the pharmacological effects of golden ear are: 1. Hypoglycemic and blood lipid-lowering effects; 2. Hepatoprotective effects such as reducing liver t...
