Abstract

The invention discloses a method for extracting hericium erinaceus polysaccharide from hericium erinaceus. The method comprises the following steps of (1) extracting hericium erinaceus by a hydrochloric acid solution with the mass fraction being 0.25 to 0.35 percent for 1 to 3h at 30 to 40 DEG C to obtain an extracting solution; (2) adding alkali into the extracting solution to regulate the pH value to be 7.5 to 8.0, and then performing solid-liquid separation to remove insoluble substances to obtain a clear water solution A; (3) adding acid into the water solution A to regulate the pH value to be 4.0 to 4.5, and then performing solid-liquid separation to remove insoluble substances to obtain a clear water solution B; (4) adding the water solution B into a macroporous absorption resin column; firstly using water to wash macroporous absorption resin to remove impurities which are not adsorbed; then using an ethanol solution with the volume fraction being 15 to 20 percent to wash the macroporous absorption resin to remove impurities with high polarity; next using an ethanol solution with the volume fraction being 65 to 70 percent as deabsorption liquid to wash the macroporous absorption resin, collecting the washed deabsorption liquid, and performing vacuum concentration and drying to obtain hericium erinaceus extracts. The method has the advantages that the process is reasonable; the extraction efficiency is high; the operation is simple; the method is suitable for industrial production.

Description

technical field [0001] The invention relates to a method for extracting Hericium erinaceus polysaccharide from Hericium erinaceus, and the invention relates to the field of biomedicine. Background technique [0002] Hericium erinaceus (scientific name: Hericium erinaceus), also known as Hericium erinaceus, Monkey mushroom, Hericium erinaceus, Hericium erinaceus, is named for its shape resembling Hericium erinaceus. [0003] The nutritional content of Hericium erinaceus is very high, and the dry product contains 26.3 grams of protein per 100 grams, which is twice that of shiitake mushrooms. It contains as many as 17 kinds of amino acids, of which 8 are needed by the human body. Every 100 grams of hericium contains 4.2 grams of fat, which is a veritable high-protein, low-fat food, and is also rich in various vitamins and inorganic salts. Hericium erinaceus has the effects of increasing appetite, enhancing the barrier function of gastric mucosa, increasing the transformation ...
