Method for extracting, separating and purifying lyciumbarbarum polysaccharide, lyciumbarbarumglycopeptide and hypoglycemic medicament

Abstract

The invention belongs to the technical filed of extraction, separation and purification; the invention discloses a method for extracting, separating and purifying lyciumbarbarum polysaccharide, lyciumbarbarumglycopeptide and a hypoglycemic medicament. The lyciumbarbarumpolysaccharide has effects in enhancing immunity, preventing aging, enhancing hematopoiesis, and preventing genetic injury; the lyceum barbarum polysaccharide (LBP) is a complex polysaccharide composed of acidic heteropolysaccharide and polypeptide or protein, and has glycopeptide structure of Glycano-O-Ser; the anti-tumor effect of the lyciumbarbarumglycopeptide is completed through an extremely complex regulation and control mode: the production of liver glycogen is inhibited by interfering the expression of related enzymes and proteins, so that the effect of reducing blood sugar is achieved. LBP has a positive effect on insulin and islet cells so as to indirectly achieve the effect of reducing blood sugar, LBP does not achieve the effect of reducing blood sugar by promoting pancreas to secrete insulin, and is a very good product for treating diabetes.

Description

technical field [0001] The invention belongs to the technical fields of extraction, separation and purification, and in particular relates to a method for extracting, separating and purifying wolfberry polysaccharides, wolfberry glycopeptides and hypoglycemic drugs. Background technique [0002] At present, the prior art commonly used in the industry is like this: the nature and flavor of wolfberry fruit are sweet and flat; the nature and flavor of wolfberry leaves are bitter and sweet; cool in nature. Functionally, wolfberry can nourish the liver, nourish the kidney and nourish the lungs. Lycium barbarum leaves have the specific effect of tonifying deficiency and benefiting essence, clearing away heat and improving eyesight. Lycium barbarum polysaccharide is a water-soluble polysaccharide, which is the most important active ingredient in wolfberry, with a relative molecular mass of 68-200; Lycium barbarum polysaccharide is one of the main active ingredients in wolfberry, w...

Problems solved by technology

Lycium barbarum polysaccharide is a water-soluble polysaccharide, which is the most important active ingredient in wolfberry, with a relative molecular mass of 68-200; Lycium barbarum polysaccharide is one of the main active ingredients in wolfberry, which has the functions of enhancing immunity, anti-aging, enhancing hematopoietic function, To prevent genetic damage and other effects, most of the prior art utilizes the crude product of Lycium barbarum polysaccharide; the purification method of the current existing technology is to use the traditional alcohol precipitation water extraction process, resulting in a yield of less than 1% for purified Lycium barbarum products, Moreover, the complex structure of the mixture cannot obtain a product that satisfies efficacy

[0004] (1) The purification methods of the existing technology all use the traditional alcohol precipitation and water extraction process, resulting in a yield of less than 1% for purified wolfberry products, and the structure of the mixture is complex, and products with satisfactory efficacy cannot be obtained;

[0005] (2) The process of the prior art is unstable, the structure of the product obtained each time is uncertain, the test results vary widely each time, and the yield is very low
