Problems solved by technology

The main feature of the sub-health state is the imbalance of immune function, such as the imbalance of the proportion of immune T cells and B cells, and the reduction or imbalance of innate immune function, which leads to the obvious decline of the human body's disease resistance. Studies have shown that immune dysfunction and Chronic inflammation, tumors, autoimmune diseases and other diseases are closely related, which seriously increases the susceptibility of diseases, endangers human health, and brings heavy economic burden to family and social development

Embodiment 1

[0054] The embodiment of the present application provides a preparation method of Ulva polysaccharide, comprising the following steps:

[0055] Soak the Ulva in appropriate amount of water for 30 minutes, rinse with clean water 3 times.

[0056] Mix clean Ulva and deionized water, heat and boil for extraction for 6 hours, wherein the mass ratio of Ulva to water is 1:10, filter through a sieve to remove Ulva residue, collect the filtrate, and centrifuge the filtrate at high speed to remove impurities to obtain an extract , concentrate it to a smaller volume by ultrafiltration to obtain a concentrated solution, carry out alcohol precipitation treatment according to the volume ratio of the concentrated solution: absolute ethanol as 1:5, collect the precipitate after standing for 30 minutes, and obtain Ulva polysaccharide by vacuum freeze-drying .

Embodiment 2

[0058] The embodiment of the present application provides a preparation method of laminarin, comprising the following steps:

[0059] Soak the kelp for 20 minutes and rinse with water 3 times.

[0060] Mix the clean kelp with sodium bicarbonate solution and heat extraction, wherein the concentration of sodium bicarbonate solution is 1‰, the condition of heating extraction is 90°C for 4 hours, the mass ratio of kelp: sodium bicarbonate solution is 1:15, through Sieve and filter to remove kelp residues, collect the filtrate, and concentrate the filtrate to a smaller volume by ultrafiltration to obtain a concentrated solution, carry out alcohol precipitation treatment according to the volume ratio of the concentrated solution: absolute ethanol as 1:4, and collect the precipitate after standing for 30 minutes. Laminarin dried by vacuum freeze drying.

Embodiment 3

[0062] The embodiment of the present application provides a preparation method of bull algae polysaccharide, comprising the following steps:

[0063] Cut bull algae into pieces, soak them in water for 20 minutes, and decolorize them with 70% alcohol for 24 hours. The algae flakes are collected by filtration, rinsed with clean water, and the pretreated bull algae is obtained.

[0064] The pretreated bull algae and the sodium bicarbonate solution are mixed and heated for extraction, the concentration of the sodium bicarbonate solution is 1%, and the conditions for heating and extraction are extracted at 95° C. for 4 hours, and the pretreated bull algae: the mass ratio of the sodium bicarbonate solution is 1: 20. Remove the bull algae residue by sieve and filter, collect the filtrate, concentrate it to a smaller volume by ultrafiltration, and obtain a concentrated solution, carry out alcohol precipitation treatment according to the volume ratio of the concentrated solution: 70% e...

Abstract

The invention belongs to the technical field of immunoregulation, and particularly relates to an algal polysaccharide composition and a preparation method and application thereof. The algal polysaccharide composition is prepared from, by mass, 22-26% of spirulina polysaccharide, 36-40% of ulva polysaccharide, 12-16% of laminarin, 14-16% of spirulina polysaccharide and 6-12% of porphyridium polysaccharide. The algal polysaccharide composition and the preparation method thereof provide an immunoregulation product which is free of toxic and side effects, high in quality and low in price.

Description

technical field [0001] The application belongs to the technical field of immune regulation, and in particular relates to an algae polysaccharide composition and its preparation method and application. Background technique [0002] The immune function system and other functional systems of the human body (such as the nervous system, endocrine system, etc.) mutually restrict and influence each other, and jointly maintain the physiological balance in the life movement. Important physiological functions, the regulation of this function is called immune regulation. [0003] It can be seen that immunity is the body's own defense mechanism. It is the body's recognition and elimination of any foreign objects (viruses, bacteria, etc.) Ability. The low immunity weakens the defense ability of the body, so that it cannot normally play a protective role. In this case, it is very easy to cause infections such as bacteria, viruses, and fungi. Therefore, the performance of low immunity is...
