This invention relates to the field of traditional Chinese medicine processing, and discloses a compound polysaccharide immune-enhancing composition and its preparation method and application. The composition comprises raw materials made from refined Polygonatum sibiricum polysaccharide, refined Dendrobium officinale polysaccharide, refined Lycium barbarum polysaccharide, and mogroside. The polysaccharides are mixed, and mogroside is added in batches with stirring and homogenization. The mixture is then dried under low temperature vacuum and granulated to produce the finished product. Mogroside molecules penetrate into the polysaccharide aggregates and reconstruct hydrogen bonds, establishing steric hindrance and rearranging charge distribution, inhibiting secondary aggregation of polysaccharides during rehydration and improving dissolution rate. Combined with step-by-step feeding and controlled moisture content, the polysaccharide conformation is solidified, preventing moisture absorption and clumping during storage and maintaining the flowability of the finished product. Purification of the polysaccharides reduces steric hindrance interference from impurities such as proteins and lignin, allowing active binding sites to be fully exposed and bind to corresponding receptors on the surface of different immune cells, thus initiating signal transduction pathways.
