Problems solved by technology

[0003] Most of the existing wolfberry polysaccharide extraction processes are traditional hot water extraction or hot water extraction after degreasing with organic solvents (ether, ethanol, petroleum ether, etc.). These conventional methods use a large amount of solvent, take a long time and have a low extraction rate. In order to improve the economic benefits of Lycium barbarum and increase the extraction rate of effective hair in Lycium barbarum, it is an important research topic for the industrialization of Lycium barbarum to find a fast and effective extraction method of Lycium barbarum polysaccharide

Embodiment Construction

[0013] After removing impurities, drying and crushing the wolfberry, use a functional extractor to degrease and decolorize the petroleum ether, filter the petroleum ether, then extract through microwaves, filter the solution, take the filtrate and add it to ethanol precipitation, and the solution is centrifuged at 8000r / min After 10 minutes, discard the supernatant to obtain a precipitate, dissolve the precipitate with distilled water, accurately absorb the solution, develop color, measure its absorbance, calculate the polysaccharide content according to the obtained regression line equation, and calculate the polysaccharide yield according to the following formula:

[0014] Lycium barbarum polysaccharide yield (%)=(the mass of polysaccharide in the filtrate) / (lycium barbarum mass)×100.

[0015] Weigh wolfberry powder, carry out microwave extraction according to the ratio of material to liquid (g / ml) of 1:10, and extraction power of 700W, and take samples every 5 minutes. .

Abstract

The invention discloses a lycium barbarum polysaccharide extraction technology, belonging to lycium barbarum polysaccharide extraction technologies. The invention provides a lycium barbarum polysaccharide extraction technology. The technology comprises the following steps of: purifying, drying and grinding lycium barbarum; degreasing and decolorizing in petroleum ether with a functional extractor; filtering out the petroleum ether; performing microwave extraction, and filtering the solution; adding anhydrous ethanol into the filtrate for alcohol precipitation; centrifuging the solution at a speed of 8,000r / min for 10min; discarding the supernatant to obtain the precipitate; dissolving the precipitate with distilled water; accurately absorbing the solution; developing and measuring the light absorption value; and calculating the polysaccharide content according to the obtained regression line equation.

Description

technical field [0001] The invention belongs to the extraction process of wolfberry polysaccharide. Background technique [0002] Lycium barbarum is a traditional traditional Chinese medicine, first recorded in "Shen Nong's Materia Medica", listed as top grade. "Compendium of Materia Medica" claims that it nourishes the kidney, nourishes the lungs, produces essence and replenishes qi. "Shenghuifang" contains wolfberry wine to tonify deficiency and damage, strengthen muscles and bones, please complexion, and keep fit. Lycium barbarum is flat in nature and sweet in taste, and has the effects of nourishing liver and kidney, benefiting energy and improving eyesight. Modern clinics are widely used in regulating immune function, lowering blood fat, lowering blood sugar, protecting liver, anti-tumor and promoting aging, etc. Lycium barbarum polysaccharide has a certain inhibitory effect on bacteria and mold, and the factor that plays an important role in the above functions of Ly...
