Abstract

The invention relates to an immunological adjuvant containing fucosan sulfate and application of the immunological adjuvant. The technical problems that at present, the kinds of immunological adjuvants are few, side effects cannot be avoided, and a great number of vaccines need to be provided when infectious diseases break out are solved. The immunological adjuvant consists of the following components in mass ratio: fucosan sulfate, ginsenoside and the rest of carriers, wherein the carriers consist of the following components in mass ratio: an emulsifying agent, an emulsifying auxiliary agent, oil phase and aqueous phase. The immunological adjuvant can be widely used in the preparation field of vaccines.

Description

technical field [0001] The invention relates to an immune adjuvant containing fucoidan sulfate, and also relates to an influenza vaccine containing the fucoidan sulfate immune adjuvant, which belongs to the fields of biotechnology and biomedicine. Background technique [0002] Fucoidan sulfate, as an intercellular polysaccharide inherent in brown algae such as kelp, exists in the cell wall matrix of brown algae and is a unique biologically active substance of brown algae. For example, Fucoidan extracted from kelp (Laminaria japonicia) is mainly composed of sulfate-containing fucose; secondly, it is also accompanied by a small amount of galactose, mannose, wood Sugar, arabinose, uronic acid, etc. are water-soluble heteropolysaccharides, also known as fucoidan and fucoidan sulfate. The main active ingredient is α-L-fucose-4-sulfate . [0003] Fucoidan sulfate is an excellent raw material for health food and pharmaceuticals. Because it naturally contains sulfate groups, it ha...
