Abstract

The invention relates to a preparation method of micromolecular dendrobium officinale polysaccharide. A dendrobium officinale dried product is used as a starting raw material, and the micromolecularden drobium dendrobium officinale polysaccharide is obtained through a deep eutectic solvent and subcritical extraction. According to the preparation method of the micromolecular dendrobium officinale polysaccharide, the dendrobium officinale polysaccharide with the molecular weight smaller than or equal to 50 kD can be prepared, and the dendrobium officinale polysaccharide with the molecular weight smaller than or equal to 50 kD further has the advantages of being high in purity and high in extraction rate. The micromolecular dendrobium officinale polysaccharide with the molecular weight smaller than or equal to 50 kDa is small in molecular weight, high in purity, beneficial to skin absorption, capable of remarkably improving the skin immune barrier effect and good in anti-inflammatory effect.
