The invention discloses wild mulberry silkworm chrysalis polysaccharide as well as a preparation method and application thereof. The polysaccharide is extracted from wild mulberry silkworm chrysalis powder, is homopolysaccharide composed of alpha-D-glucose, and comprises 1, 4-linked alpha-D-glucose residues, 1, 4, 6-linked alpha-D-glucose residues and 1-linked alpha-D-glucose residues, and the molar ratio of the sugar residues is 4: 1: 1. The wild mulberry and silkworm chrysalis polysaccharide has remarkable immunoregulatory activity, can be used for preparing medicines, can also be used for preparing health-care products and food for enhancing immunity, has better application prospects and commercial value, and can also improve the utilization value of silkworm chrysalis. 本发明公开一种野桑蚕蛹多糖及其制备方法和应用。该多糖由野桑蚕蛹粉末提取得到，其为由α-D-葡萄糖组成的同多糖，包含1,4-连接的、1,4,6-连接的和1-连接的α-D-葡萄糖残基，上述糖残基的摩尔比为4:1:1。该野桑蚕蛹多糖具有显著的免疫调节活性，可用于制备药物，也可用于制备增强免疫的保健品和食品，具有较佳的应用前景和商业价值，还可提高蚕蛹的利用价值。
