This invention discloses a lily
polysaccharide composition, its preparation method, and its applications, belonging to the field of
biomedicine and
functional food technology. The lily
polysaccharide composition includes water-extracted polysaccharides, acid-extracted polysaccharides, and alkali-extracted polysaccharides extracted from lily. Furthermore, this invention provides a method for preparing the above-mentioned lily
polysaccharide composition, comprising the following steps: S1, preparation of water-extracted polysaccharide LSWP; S2, preparation of acid-extracted polysaccharide LSAP; S3, preparation of alkali-extracted polysaccharide LSKP; S4, mixing the water-extracted polysaccharide LSWP, the acid-extracted polysaccharide LSAP, and the alkali-extracted polysaccharide LSKP to obtain the lily polysaccharide composition. In addition, this invention also proposes an application of the above-mentioned polysaccharide composition in the preparation of immunomodulatory drugs and / or anti-inflammatory drugs, functional foods, or health products. This polysaccharide composition exhibits excellent immunomodulatory and anti-inflammatory activities.
