Embodiment 1

[0017] A method for extracting and purifying polysaccharides from Desmodium desmodium, comprising the following steps: extracting 300 g of dried desmodium desmodium with 1800 ml of ether Soxhlet for 2 hours to remove oil, and evaporating the residue to dryness. The residue after evaporating to dryness was extracted three times with 750ml boiling water, combined the boiling water extracts obtained three times, concentrated, centrifuged, and the supernatant was taken, and the supernatant was added with absolute ethanol 3 times the volume of the clear liquid for alcohol precipitation, and stood overnight (12h), centrifuge again to collect the precipitate. The precipitate was washed three times with 300ml ethanol and 300ml acetone in turn, and then dissolved in distilled water, then papain with a weight of 1‰ of the precipitate was added and placed in a water bath at 50°C for 2 hours, and the protein was removed by the Sevage method. Add 8g of activated carbon and place it in a 70...

Embodiment 2

[0020] A method for extracting and purifying polysaccharides from Desmodium desmodium, comprising the following steps: extracting 300g of dried Desmodium desmodium with 2000ml of ether Soxhlet for 4 hours to remove oil, and evaporating the residue to dryness. The residue after evaporating to dryness was extracted with 750ml of boiling water for 3 times, and the boiling water extracts obtained three times were combined, concentrated, centrifuged, and the supernatant was taken, and anhydrous ethanol with 3 times the volume of the clear liquid was added for alcohol precipitation, and stood for 12 hours , and centrifuge again to collect the precipitate. The precipitate was washed three times with 300ml of ethanol and 300ml of acetone in turn, then dissolved in distilled water, and then papain with a weight of 2‰ of the precipitate was added, placed in a water bath at 50°C for 4 hours, and the protein was removed by Sevage method.

Abstract

The invention relates to a desmodium polysaccharide and its extraction and purification method, specifically: extracting the crushed dry desmodium with ether Soxhlet, volatilizing the residue and then extracting it with boiling water, concentrating and centrifuging the boiling water extract, and taking the supernatant Let the liquid alcohol settle down, collect the precipitate by centrifugation again, dissolve it with distilled water after washing, then add 1-2‰ papain, place it in a water bath at 50±5°C for 2-4 hours, use the Sevage method to remove the protein, decompress with activated carbon Concentrate, cool down, and dialyze with running water. After the dialyzing is over, let it stand for alcohol precipitation again, and dry the precipitate at 60-70°C to obtain crude polysaccharide. The test proves that the desmodium polysaccharide of the present invention has a good physical and sensory moisturizing effect on cigarettes, and can reduce the irritation and miscellaneous gas of cigarettes, improve the roundness and comfort of cigarette smoke, and can be used as a kind of cigarette with excellent performance. Tobacco humectants are used in cigarettes.

Description

technical field [0001] The invention belongs to the technical field of humectants, and in particular relates to a desmodium polysaccharide, an extraction and purification method and its application as a tobacco humectant. Background technique [0002] At present, glycerin, propylene glycol, sorbitol and other polyhydroxy substances are mainly used as humectants in the cigarette industry in my country. The main purpose of using such humectants is to maintain the moisture content of shredded tobacco during processing and improve the processing resistance of shredded tobacco. The above-mentioned humectant has unsatisfactory effects on maintaining the moisture content of finished cigarettes and improving smoking comfort. [0003] Polysaccharides are composed of a large number of monosaccharides, and a large number of hydroxyl groups form hydrogen bonds with water molecules, which can make them have strong water holding capacity. At present, there is no relevant report on the app...
