Problems solved by technology

Previous scientific research mostly focused on extracting polysaccharides from mussels, mud snails and other shellfish by acid method, alkali method or enzymatic hydrolysis method, but the enzyme extraction technology is easily limited due to the specificity of the enzyme, and the extraction technical conditions More stringent, the decomposed extraction solution is easy to be mixed with other non-target products, and other separation steps are needed to obtain high-purity polysaccharides in the follow-up. Destroy the activity of white shellfish polysaccharide
[0004] In addition, the current main method for polysaccharide activity research is to first extract and purify crude polysaccharides, further separate and obtain each component, and then conduct activity detection; this method has many uncertain factors, and active polysaccharide components are easily lost during the separation process, and extraction and separation The obtained shellfish polysaccharides may not be active, which leads to the lack of orientation in the subsequent separation and purification of each component, and there is a waste of resources such as material resources, manpower, and financial resources.

Abstract

The invention discloses a method for extracting monetaria moneta Linnaeu acidic polysaccharose with oxidization resisting and liver protecting effects from monetaria moneta Linnaeu. According to the method, oxidization resistance or liver protection activity is utilized as basis, a water extract and alcohol precipitation method and a Sevag deproteinization method are combined, and the monetaria moneta Linnaeu acidic polysaccharose is extracted from the monetaria moneta Linnaeu for the first time. The method disclosed by the invention has the advantages of simple extracting technology steps, moderate and low-requirement operation conditions, no corrosion to operation equipment, environmental friendliness, no byproduct generation and low production cost, the prepared monetaria moneta Linnaeupolysaccharose has good oxidization resistance and liver protecting activity, and a novel choice is provided for preparing oxidization resisting / liver protecting medicine or health-care products.

Description

technical field [0001] The invention relates to a method for shellfish polysaccharides, in particular to a method for extracting white shellfish acidic polysaccharides with antioxidant and liver-protecting effects from white shellfish. Background technique [0002] Bai Bei ( Monetaria moneta Linnaeus), an edible shellfish, widely exists in the South my country Sea. White shellfish was first recorded in "Shen Nong's Materia Medica", which has the functions of clearing away heat, improving eyesight, diuresis and reducing cloudiness. Modern scientific research has proved that white shellfish is rich in various nutrients, such as polysaccharides, proteins and trace elements. Among them, polysaccharides have many The health care functions of shellfish, such as anti-oxidation, antibacterial, anti-cancer, etc., and most of the biological effects of white shellfish are related to polysaccharides. [0003] At present, there are not many research reports on white shellfish, and the...
