Embodiment 1

[0040] Example 1. Far-infrared-assisted hydrolysis of polysaccharides from Cordyceps sinensis.

[0041] (1) Extraction of polysaccharides from Cordyceps sinensis

[0042] In Example 1, the polysaccharides of Cordyceps sinensis were extracted by the water-alcohol precipitation method, and the samples of Cordyceps sinensis were dried in an oven at 60°C for 3 hours, then mechanically pulverized into powder, and 3 grams of Cordyceps sinensis powder samples were weighed and dispersed in 30 ml of water, and extracted under reflux in a water bath at 100°C 30 minutes, then ultrasonically extracted for 10 minutes, the mixture was filtered to obtain a filtrate, the filtrate was added with an equal amount of absolute ethanol, mixed thoroughly, and centrifuged at 4000 rpm for 10 minutes to separate the polysaccharide precipitate. The precipitate was washed successively with absolute ethanol and acetone, sucked dry under reduced pressure, and then dried in a solid powder drying oven at 60°...

Embodiment 2

[0052] Example 2. Far-infrared-assisted hydrolysis of Radix isatidis polysaccharide.

[0053] Take 3 grams of 24-mesh isatidis powder, add 30 ml of water, heat to boiling and reflux for 30 minutes to extract polysaccharides, then ultrasonically extract for 10 minutes, add the same amount of absolute ethanol to the filtrate obtained by filtration, and centrifuge at 4000 rpm After 10 minutes, the polysaccharide precipitate was separated. The precipitate was washed successively with absolute ethanol and acetone, sucked dry under reduced pressure, and then dried in a solid powder drying oven at 60°C to obtain the Radix isatidis polysaccharide polysaccharide. Weigh about 3 mg Radix isatidis polysaccharide samples dissolved in 3 ml of 2 mol / liter trifluoroacetic acid aqueous solution, in the attached figure 1 The Radix Radix isatidis polysaccharide can be completely hydrolyzed by hydrolysis for 15 minutes in the shown far-infrared hydrolysis device. Due to the small volume of the ...

Abstract

The invention belongs to the technical field of polysaccharide structure analysis and in particular discloses a far-infrared assisted efficient polysaccharide hydrolysis device and method. According to the device, a far-infrared generator, a backflow condensation tube, a hydrolysis container and a pressure regulator are assembled to form a polysaccharide hydrolysis device, polysaccharide is subjected to far-infrared assisted hydrolysis in a hydrolysis container after being dissolved into an aqueous solution with a volatile acid, and can be applied to later monosaccharide spectrum analysis after hydrolysis is completed and the volatile acid is sucked off. Since far-infrared rays can be intensively absorbed by the polysaccharide and solution molecules, vibration of polysaccharide molecules and actions of the polysaccharide molecules with the acid aqueous solution can be accelerated, and the polysaccharide hydrolysis efficiency can be remarkably improved. A far-infrared radiation non-contact heating technique is adopted to replace water bath used in conventional polysaccharide hydrolysis, the polysaccharide hydrolysis time is greatly shortened within 15 minutes from hours of water bath heating hydrolysis, and the hydrolysis effect is remarkably improved. The far-infrared assisted efficient polysaccharide hydrolysis device has the advantages of being simple in equipment, low in energy consumption and simple and convenient to operate, and has good application prospects in polysaccharide structure analysis techniques.

Description

technical field [0001] The invention belongs to the technical field of polysaccharide structure analysis, and in particular relates to a far-infrared-assisted high-efficiency polysaccharide hydrolysis device method. Background technique [0002] Sugars that can be hydrolyzed into multiple monosaccharide molecules or their derivatives are polysaccharides. It is a macromolecular compound formed by condensation and dehydration of 20 to tens of thousands of monosaccharide molecules. Polysaccharides can be formed by condensation of one monosaccharide, such as starch and cellulose, which are called homopolysaccharides; they can also be formed by condensation of different monosaccharides or their derivatives, such as hemicellulose, which are called heteropolysaccharides. Polysaccharides are the most abundant biopolymers in nature. They exist in almost all organisms and have many biological functions such as energy storage, structural support, defense function and antigenic determi...
