Claims8
An extract derived from a mushroom of the Lentinus genus comprising monosaccharides, polysaccharides, and by weight, from 2% to 8% of trehalose, from 1% to 4% of glucose and from 30% to 60% of alditols, relative to the total weight of the dry extract prepared by a method comprising:
- performing at least one extraction on mushrooms of the Lentinus genus comprising boiling the mushrooms in distilled water to obtain a liquid extract and stirring the liquid extract for about 30 minutes at about 90° C.;
- treating the liquid extract with an organic solvent to form a precipitate;
- centrifuging and filtering the precipitate;
- and
- drying the precipitate to obtain the extract.
