Abstract

The invention discloses an extraction method of a hericium erinaceus anti-allergic active polysaccharide. According to the extraction method, the hericium erinaceus anti-allergic active polysaccharideis obtained by adopting a technology comprising hot water extraction and DEAE (Diethyl Aminoethanol) Sepharose Fast Flow ion exchange chromatography purification. After the hericium erinaceus anti-allergic active polysaccharide obtained by the extraction method is subjected to high performance gel permeation chromatography detection, the hericium erinaceus anti-allergic active polysaccharide hasa single symmetrical peak and uniform purity; the molecular weight calculated relative to a standard curve is 10kDa; the hericium erinaceus anti-allergic active polysaccharide has an obvious inhibition effect on hyaluronidase and has anti-allergic activity.

Description

technical field [0001] The invention relates to the technical field of preparation of anti-allergic active polysaccharides, in particular to a method for extracting anti-allergic active polysaccharides from Hericium erinaceus. Background technique [0002] Hericium erinaceus (Hericium erinaceus) is a well-known medicinal and edible fungus in China. It has attracted much attention because of its biological activity in the prevention and treatment of gastritis and stomach protection. At present, a variety of active ingredients in Hericium erinaceus have been studied, such as polysaccharides, alkaloids, terpenoids, phenolic acids, etc. Research on the active ingredients of Hericium erinaceus has also expanded from stomach protection, immune regulation, anti-tumor, and anti-oxidation to improving mild cognitive impairment, antibacterial, and anti-inflammatory aspects. However, there are few studies on the antiallergic activity of Hericium erinaceus polysaccharides. The relevan...
