Abstract

The invention discloses a soft coral polysaccharide and a preparation method and application thereof. The monosaccharide components in the soft coral polysaccharide are: mannose, rhamnose, glucuronic acid, glucose, galactose and xylose. In the present invention, the inventors extracted and isolated soft coral polysaccharide from Lobophytum sp. for the first time, and found that the soft coral polysaccharide can promote the proliferation of RAW264.7 macrophages, and promote the secretion of NO, IL-1β, IL-1β, Cytokines such as TNF-α and IL-6 can also improve the phagocytic ability of cells and can be used as a better immune regulator. The extraction process provides an effective technical reference for the development and improvement of the subsequent extraction process of coral polysaccharides. It has important research significance and development value for the utilization of coral polysaccharides.

Description

technical field [0001] The invention belongs to the field of natural product extraction, in particular to a soft coral polysaccharide and a preparation method and application thereof. Background technique [0002] Lobophytum sp. belongs to Coelenterata, Anthozoa, Octocorallia, Alcyonacea, Alcyoniidae. It is a marine lower invertebrate, commonly found in tropical and subtropical waters. The pod soft coral has various colors and is very ornamental. It mainly feeds on plankton in the ocean and is a kind of seabed attached organism. Pod soft corals are hardly aggressive, and individual corals can live for hundreds of years under the right conditions. [0003] According to the Compendium of Materia Medica, coral can be used medicinally. Coral reefs in the ocean are rich in resources, accounting for about 22.4% of the total marine organisms. In related technologies, the research on corals is limited to secondary metabolites, and there is little research on polysaccharides. As ...
