Abstract

The invention discloses a preparation method of a dendrobium huoshanense polysaccharide. The preparation method comprises the following steps of 1), crushing; 2), pulping; 3), extraction; 4), alcoholprecipitation; 5), discoloration treatment; 6), enzymolysis; 7), alcohol precipitation once again; 8), filtration; 9), third-time alcohol precipitation; 10), centrifugal separation; 11), freeze-drying, so as to obtain a dendrobium huoshanense polysaccharide pure product. A raw material adopted by the preparation method is subjected to the freeze-drying and superfine grinding; effective componentscan be prompted to be quickly dissolved out; much water is added in the extraction step for high-temperature extraction; the sufficient extraction of the effective components is facilitated, and a dendrobium huoshanense polysaccharide product obtained by the preparation method provided by the invention is high in extraction rate and high in purity, meanwhile, has excellent drug activity, and has an outstanding advantage in application.
