Cyclocarya paliurus polysaccharide extraction and method for preparing cyclocarya paliurus polysaccharide solid beverage

Abstract

A method for extracting the cyclocarya paliurus polysaccharide comprises the following steps of: (1) sequentially carrying out freeze-drying, crushing and sieving on raw materials; (2) degreasing, vacuumizing and filtering; (3) pulping and carrying out enzymolysis for the first time; (4) adding ethanol, performing ultrasonic treatment, and filtering to obtain residue; (5) performing enzymolysis for the second time; (6) refluxing and extracting, centrifuging and collecting filtrate and residue; (7) concentrating and distilling the filtrate under reduced pressure, adding ethanol, centrifuging, and collecting precipitate; (8) washing the precipitate and filtering to obtain a cyclocarya paliurus crude polysaccharide blank; (9) purifying the blank; (10) preparing cyclocarya paliurus crude polysaccharide aqueous solution, adding chloroform and n-butanol solution, taking supernatant, adding ethanol, centrifuging, collecting the precipitate, and freeze-drying to obtain cyclocarya paliurus polysaccharide. The method has the advantages that the operation method is simple, the extraction content of the cyclocarya paliurus polysaccharide is improved, the quality is greatly improved, and the preparation of the solid beverage by using the cyclocarya paliurus polysaccharide is beneficial to improving the economic value of the cyclocarya paliurus polysaccharide.

Description

technical field [0001] The invention belongs to the technical field of extracting active ingredients from natural medicinal plants, and in particular relates to a method for extracting paliurus paliurus polysaccharide and preparing a polysaccharide solid beverage of paliurus paliurus paliurus. Background technique [0002] Cyclocarya is also often called money tree, green plum, camellia, sweet tea tree, etc. It is a deciduous tree of the Juglandaceae Cyclocarya genus. It is a unique single-species plant in my country and a national second-level protected tree species. It is distributed in Henan, Mountainous areas in Hubei, Hunan, Jiangxi, Guangxi, Guizhou and other provinces. Folks often pick its tender leaves to make tea for drinking. According to the historical records of traditional Chinese medicine, green caraway tea has many functions such as promoting body fluid and quenching thirst, clearing away heat and relieving summer heat. The research on Cyclocarya paliurus can ...
