摘要： A natural biological liquid extract comprising plant (e.g. vegetable) and/or animal and/or prokaryotic biological material obtained by the extraction method, wherein the method comprises the following steps:
a. immersing, while stirring, a ground or unground biological material in a solvent, wherein the solvent is a clear, stable and fluid mixture comprising:
(i) betaine (trimethyl glycine) or a hydrated form of betaine;
(ii) at least one hydrogen bond donor compound selected from the group consisting of polyols and organic acids; and
(iii) water;
wherein the ratio of betaine or a hydrated form of betaine to the at least one hydrogen bond donor is from 1:1.5 to 1:3 and the proportion of water added to the mixture is from 15 to 30% by weight;
with the proviso that the eutectic extraction solvent does not contain any exogenous sugar and/or amine salt and/or anion; b.
macerating or percolating or infusing the mixture obtained in step a. at a temperature between 20 and 60°C; then
c. filtering the extraction product obtained at b., thereby obtaining a natural biological liquid extract derived from the plant (e.g. vegetable) and/or animal and/or prokaryotic biological material.
