Abstract

The invention relates to the technical field of chemical extraction of effective components, in particular to a process for extracting polysaccharide from hericium erinaceus spore powder, and the process comprises the following steps: S1, carrying out wall breaking treatment on the hericium erinaceus spore powder to obtain wall-broken hericium erinaceus spore powder; s2, mixing the wall-broken hericium erinaceus spore powder with a mannitol solution according to a solid-to-liquid ratio of 1g: (60-88) mL, and carrying out heating treatment for 45-70 minutes to obtain a wall-broken hericium erinaceus spore powder solution; s3, introducing nitrogen into the wall-broken hericium erinaceus spore powder solution, keeping for 12 minutes to half an hour under the pressure condition of 1-1.3 MPa, and quickly reducing the pressure to standard atmospheric pressure to obtain a polysaccharide crude extract; and S4, carrying out alcohol precipitation separation on the polysaccharide extracting solution, concentrating and drying to obtain the polysaccharide extract. The process provided by the invention is high in polysaccharide extraction yield, high in weight-average molecular weight of polysaccharide, low in equipment requirement and suitable for large-scale industrial production.

Description

technical field

[0001] The invention relates to the technical field of chemical extraction of active ingredients, in particular to a process for extracting polysaccharides from Hericium erinaceus spore powder. Background technique

[0002] Hericium erinaceus spore powder is the powder released when Hericium erinaceus grows and matures. It belongs to sexual spores, similar to plant pollen. Hericium erinaceus spore powder has the same nutritional content as Hericium erinaceus, and it is effective in disease prevention and treatment. It is not inferior to Hericium erinaceus fruiting bodies or Hericium erinaceus mycelium, but there is no targeted use of Hericium erinaceus spore powder at present, and the utilization of Hericium erinaceus spore powder is not sufficient.

[0003] Hericium erinaceus spore powder contains polysaccharides that also exist in the parenchyma of Hericium erinaceus. Utilize the extraction methods of Hericium erinaceus polysaccharides in the prior art, suc...
