Abstract

The invention discloses an aqueous extraction method of cinnamon polysaccharides. The aqueous extraction method of the cinnamon polysaccharides comprises the following steps: cinnamomum is smashed into 60 meshes, petroleum ether is added for reflux and degreasing, the solid-liquid ratio is 1:20, and extraction with hot water is performed after a solvent is volatilized; the extraction temperature is 100 DEG C, the pH value is 5, and the extraction time lasts for 2h; an extract liquid is filtered, concentrated and precipitated with absolute ethanol with the volume being eight times that of the extract liquid, suction filtration is performed, filter residues are obtained, dried and washed with absolute ethanol three times, vacuum drying is performed, and the cinnamon polysaccharides are obtained. With the yield of water-soluble polysaccharides taken as the index, the single-factor experiment and orthogonal experiment research of the extraction process of the water-soluble cinnamon polysaccharides is performed, extraction optimized technological parameters of the cinnamon polysaccharides is obtained, and scientific basis is provided for the research and development of cinnamon. The reproducibility of optimized conditions is good, and industrial production is facilitated. The cinnamon total polysaccharides extracted with the method has an effect in reducing blood glucose of mice with diabetes, and a theoretical basis is provided for further development of medicinal value of cinnamomum.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction, and in particular relates to a water extraction method of cinnamon polysaccharide. Background technique [0002] Cinnamon (Cinnamomum cassia presl), a Lauraceae plant, its dry bark is one of the articles that can be used as food and medicine as announced by the Ministry of Health of my country. my country is the main producing area of ​​cinnamon, rich in cinnamon resources. The chemical components contained in cinnamon include volatile oil, phenols, organic acids, tannins, polysaccharides, glycosides, steroids, lactone, coumarin, etc. Pharmacological tests have shown that cinnamon polysaccharides have physiological activity of lowering blood sugar. There is a literature report on a method for extracting cinnamon polysaccharides: crush cinnamon into coarse powder, add 5 times the amount of petroleum ether to reflux twice, each time for 2 hours, and filter; the filter residue i...
