The invention belongs to the technical field of medicines, and particularly relates to acetylated hawthorn
polysaccharide as well as a preparation method and application thereof. The preparation method of the acetylated hawthorn
polysaccharide comprises the following steps: adding fresh hawthorn fruits into a deep-eutectic
solvent for homogenization, and extracting by adopting a physical method to obtain an extracting solution; carrying out
alcohol precipitation and
centrifugation on the extracting solution to prepare crude
polysaccharide; and adding water into the crude polysaccharide, redissolving, deproteinizing, concentrating, dialyzing and freeze-
drying to obtain the acetylated hawthorn polysaccharide. The method utilizes a physical method to cooperate with
deep eutectic solvent extraction, is green and
pollution-free, can realize efficient preparation and effective separation of acetylated hawthorn polysaccharide, has high
acetylation degree, has in-vitro and in-vivo intestinal mitochondrial
homeostasis regulation activity, has no toxic or
side effect, is suitable for people with intestinal mitochondrial related diseases, and also has the functions of improving intestinal mitochondrial
homeostasis regulation. And the composition is also suitable for preventing intestinal diseases of
normal people.
