Abstract

The invention discloses a polysaccharide which is extracted from Chinese pistache and the extraction method; the polysaccharide is extracted by the following steps: the Chinese pistache raw material is added in the strong acidic solution, which is taken as extracting solution and has a concentration of 0.01 to 7mol / L, or the weak acid with the weight percentage concentration of 0.01 percent to 100 percent or the alkaline solution with the concentration of 0.05 to 8.0mol / L or the water according to the material liquid ratio of 1: 1 to 1:200g / ml and is taken out after 1 minute to 8 hours of extraction, the solution after removing the sediment is obtained by centrifugal separation or filtration, then the sufficient amount of solvent is added for full precipitation of the polysaccharide, finally the solution is removed by centrifugalization or filtration, anhydrous ethanol, propyl alcohol or propyl alcohol are used for washing for a plurality of times, and the crude polysaccharide is obtained by freeze drying. The extraction method takes the commonly used acidic solution and alkaline solution or water as the extracting liquid, the extraction conditions are simple and convenient, and the extraction method further takes the ultrasonic or microwave extraction as auxiliary means; the extraction method has higher polysaccharide yield, can greatly improve the additional values of processing and utilizing of the Chinese pistache and has great popularization and application prospects on the industrial aspect.

Description

technical field [0001] The invention relates to a polysaccharide extracted from coptis wood dregs and an extraction method thereof, belonging to the field of biochemistry. Background technique [0002] Pistacia chinensis, also known as medicine tree, medicine tree, etc., belongs to the genus Pistacia chinensis in the Anacardaceae family. It is native to my country and has a wide distribution. It is distributed in North China, East China, Central South, Southwest, South China, Northwest and other places in China. It is also naturally distributed in the Philippines and other places in Southeast Asia. Recent studies have shown that Pistacia chinensis seed oil can be used to extract biodiesel, which is of great significance to solve the current energy crisis, but there are few reports on the development and utilization of its cake after oil extraction. Many plant polysaccharides have been widely studied and utilized as natural active and beneficial macromolecular substances. Ex...
