Abstract

The present invention relates to a method for preparing guluronic acid oligosaccharide by Fenton reaction, which comprises the steps that poly guluronic acid is prepared into 0.1 to 5 wt % of water solution; the present invention is characterized in that an oxidizing agent is added in the water solution until the concentration is from 0.05 to 0.5%, metal ions are added until the concentration of the water solution is from 0.05 to 0.5%, and the water solution is reacted at the temperature of 20 to 40 DEG C; then, reaction solution is separated and purified by Bio-gelP10 and a Q-Sepharose Fast Flow chromatography column after the stopping of reaction. The present invention for preparing the guluronic acid oligosaccharide has the advantages of high reaction speed, high product purity, easy separation and purification, mass production of the guluronic acid oligosaccharide, full utilization of the guluronic acid oligosaccharide, and wide development of function and activity of the mannuronic acid oligosaccharide.

Description

Utilize Fenton's reaction to prepare the method for guluronic acid oligosaccharides
Technical field
The present invention relates to a kind of method of utilizing Fenton (Fenton) prepared in reaction guluronic acid oligosaccharides.
Background technology
Algin is the linear anionic polysaccharide that is connected to form by 1,4 glycosidic link by beta-D-mannuronic acid and α-L-guluronic acid.Above-mentioned two kinds of uronic acid homogeneous or alternately arrangement, the algin fragment that homogeneous is arranged comprises polymannuronic acid (PM) and poly-guluronic acid (PG).The algin source is abundant, and has been widely used in food, chemical industry and pharmaceutical sector etc.Algin oligosaccharide comprised that the physiological action of guluronic acid oligosaccharides constantly was found in recent years, and it has the function of stronger promotion plant-growth, and anticoagulant active, antiviral activity, anti-microbial activity are arranged; Can improve immunizing power, anti-tumor activity and anti-inflammatory activity.Therefore the demand of guluronic acid oligosaccharides grows with each passing day, and has caused the concern that people are bigger.
Summary of the invention
The purpose of this invention is to provide a kind of method of the Fenton of utilization prepared in reaction guluronic acid oligosaccharides, it can satisfy the demand of prior art.
A kind of method of utilizing Fenton's reaction to prepare the guluronic acid oligosaccharides, comprise and to gather guluronic acid to be made into concentration expressed in percentage by weight be 0.1~5% the aqueous solution, it is characterized in that adding oxygenant to concentration to this aqueous solution is 0.05-0.5%, add metal ion to concentration 0.05-0.5%, 20~40 ℃ of reactions down, after the stopping of reaction, reaction solution is concentrated, use Bio-gel P10 then, the separation and purification of Q-Sepharose Fast Flow chromatography column; Described oxygenant is a hydrogen peroxide; Described metal ion is a ferrous ion.
The method for preparing the guluronic acid oligosaccharides of the present invention, speed of response is fast, and the product purity height is easy to separation and purification, and energy mass production guluronic acid oligosaccharides is fully used it, and its function and activity also can be developed widely.
Embodiment
To gather guluronic acid and be made into 2% (concentration expressed in percentage by weight, as follows) the aqueous solution, adding oxidants hydrogen peroxide to concentration is 0.1%, and adding ferrous sulfate to concentration is 0.4%, 25 ℃ of reactions down, after the stopping of reaction, reaction solution is concentrated, use Bio-gel P10 then, the separation and purification of Q-Sepharose FastFlow chromatography column, obtain guluronic acid series oligosaccharides, its structural formula is:
Figure C20031010569400041
N is 1-19 in the formula.
Oxygenant described in the present invention is hydrogen peroxide, hypochlorous acid, hypochlorite or sulfuric acid.Described metal ion is bivalent cupric ion, iron ion.The concentration expressed in percentage by weight of described poly-guluronic acid in the aqueous solution is 0.1-1.5%, and the concentration of oxygenant and metal ion is 0.05-0.5%, and temperature of reaction is 20-40 ℃.
