Title:
BIOLOGICALLY ACTIVE SUBSTANCE, METHOD FOR MANUFACTURING SAME AND USE THEREOF AS AN AGENT FOR PROTECTING A BIOLOGICAL TISSUE
Document Type and Number:
WIPO Patent Application WO/2020/128991
Kind Code:
A1
Abstract:
The biologically active substance is obtained or capable of being obtained by alkaline extraction, using an aqueous solution of at least one base in the presence of at least one reducing agent, of at least one macroscopic edible mushroom reduced to powder, to obtain a mixture having a liquid portion containing the soluble extracted materials and a solid portion formed of insoluble solid particles; filtering the resulting mixture to remove the solid portion and optionally clarifying the liquid portion; neutralising the liquid portion using at least one cation exchange resin and optionally filtering/clarifying the liquid portion thus neutralised to obtain the biologically active substance in the aqueous phase; and treating the resulting aqueous phase, the treatment being selected from dilution in water, concentration, dehydration and lyophilisation, to obtain a biologically active substance which is, respectively, more diluted in water, in an aqueous solution that is more concentrated, dehydrated in powder form or lyophilised.
