Method for preparing schisandra active component polysaccharides

Abstract

A preparation method of active component in schisandra chinensis, including the preparation steps of the raw material treatment, the polysaccharide extraction, the ethanol classification, the protein removal, the alcohol precipitation and the drying. The raw material treatment is to immerse fresh schisandra or dry schisandra and separate fruit pulp and seeds after the multiple beating; the polysaccharide extraction is to use one or two of cellulose and pectinase for the enzymatic hydrolysis which are extracted with water; the ethanol classification is to add polysaccharide solution in ethanol solution; the protein removal method is to combine acid protease with Sevag. The invention provides a method of extracting the active component polysaccharide from the schisandra, especially paves a way for extracting the active component by a fresh fruits extraction method and a seed-fruit separation method. Both resources and energies are saved and the extraction cost is lowered. And the invention provides the technical support to the reasonable development of the schisandra.

Description

technical field [0001] The invention relates to a production method of schisandra polysaccharide, a functional active ingredient of schisandra chinensis. Background technique [0002] Schisandra chinensis (Tarcz.) Bail1. is the mature fruit of Magnoliaceae Schisandra chinensis (Tarcz.) Bail1. Since the 1950s, scholars from China, Japan, the former Soviet Union and other countries have used modern scientific methods to do a lot of research, proving that Schisandra can reduce serum alanine aminotransferase in patients with hepatitis; treat chemical poison damage to the liver; have an excitatory effect on the central nervous system , can enhance the defense ability of the body to non-specific stimuli; increase the blood pressure of patients with hypotension, but not normal blood pressure; affect the excitation and inhibition of the cerebral cortex, improve people's intelligence, increase memory; enhance the function of the adrenal cortex, Promotes heart activity. Its function...

Problems solved by technology

[0004] However, the above research and patent reports on Schisandra polysaccharides are all reports on the whole fruit of Schisandra chinensis, and most of them are the dried fruits of Schisandra chinensis studied, and there are no reports of fresh fruits

In view of the functional components lignin and polysaccharides of Schisandra chinensis, the contents of different parts have important differences. The polysaccharides of Schisandra chinensis are mostly concentrated in the pulp, and 90% of the lignin is concentrated in the seeds. Using the whole fruit to extract polysaccharides is not conducive to the activity Separation of components and easy waste of resources

In addition, the above reports all use the hot water extraction method to extract polysaccharides, and there are few reports on the method of removing protein. Some use trichloroacetic acid to remove protein. Because of its strong acidity, it is easy to destroy the polysaccharide structure, which is not conducive to the protection Physiological activity of polysaccharides
