Problems solved by technology

However, due to the complexity of the structure of the polysaccharide itself, it is difficult to clarify the relationship between the chemical structure of the active ingredient and these functional activities, and the mechanism of action is difficult to clarify, which hinders the development of polysaccharide drugs or health products.
[0004] At present, the research on polysaccharide extraction technology at home and abroad mostly adopts the traditional hot water extraction method, which has a single extraction solvent and is difficult to release polysaccharides from plant cells; moreover, water extraction and alcohol precipitation are often used in laboratories to obtain crude polysaccharides. However, the molecular weight of polysaccharides prepared by the current process is relatively dispersed and chaotic, the active ingredients are unknown and the reproducibility is poor, and targeted research cannot be carried out

Abstract

The invention discloses a preparation method and application of jasmine flower residue active polysaccharide, and belongs to the technical field of plant extraction. The jasmine flower residue activepolysaccharide is prepared by taking a jasmine flower byproduct, jasmine flower residues, as a raw material through the steps of jasmine flower residue pretreatment, jasmine flower residue total extract preparation, total extract fractional extraction, jasmine flower residue crude polysaccharide preparation, jasmine flower residue polysaccharide separation and purification and the like. Accordingto the method, the jasmine flower residue polysaccharides with different molecular weights can be prepared, and the jasmine flower residue polysaccharides with different functional activities can be efficiently separated and purified. According to different molecular weights, the jasmine flower residue polysaccharide disclosed by the invention can be applied to preparation of medicines for regulating immunity, anti-insomnia or anti-depression medicines, anti-diabetic medicines and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of plant extraction, and in particular relates to a preparation method and application of jasmine residue active polysaccharide. 【Background technique】 [0002] Jasmine slag is the waste and foreign matter after the jasmine buds in the genus Jasmine of Oleaceae are smoked for tea, and it is the main waste in the process of processing and producing jasmine tea. Air-dried samples are yellow-brown in color and have a strong jasmine fragrance. Jasmine slag contains 20.8% of crude protein, 2.4% of crude fat, 12.4% of crude fiber, 8.04% of water-soluble carbohydrate, 3.41% of free amino acid, and 0.21% of vitamin C. Jasmine slag is usually treated as waste, resulting in waste of resources and environmental pollution. At present, domestic and foreign research on jasmine residue polysaccharides mainly focuses on the polysaccharide extraction process, and there are few reports on the separation and purification o...
