| description | The invention relates to the technical field of plant extraction, and particularly discloses a high-molecular-weight and low-molecular-weight dendrobium officinale polysaccharide extracting solution as well as a preparation method and application thereof. According to the preparation method, firstly, the macromolecular dendrobium officinale polysaccharide is prepared through a microbial fermentation method, and the extraction rate of the dendrobium officinale polysaccharide is increased; furthermore, in consideration that the solubility of the high-molecular-weight dendrobium officinale polysaccharide is relatively low and the dendrobium officinale polysaccharide is not beneficial to crossing multiple cell membrane obstacles to enter organisms, the immobilized compound enzyme is adopted for performing enzymolysis on the crude fermentation liquor, and the high-molecular-weight dendrobium officinale polysaccharide in the crude fermentation liquor is partially subjected to enzymolysis to obtain the low-molecular |
