Abstract:
1. A method of obtaining a product containing at least one glycoside of a mono- or diacylglycerol selected from the group consisting of 3 β- D -galactopyranosyloxy-2-(octadeca-9Z,12Z,15Z-trienoyloxy)propanyl octadeca-9Z,12Z,15Z-trienoate, 3β- D -glucopyranosyloxy-2-(octadeca-9Z,12Z,15Z-trienoyloxy)propanyl octadeca-9Z,12Z,15Z-trienoate, 3-α- D -galactopyranosyloxy-2-(octadeca-9Z,I2Z,I5Z trienoyloxy)propanyl octadeca-9Z,12Z,15Z-trienoate, 3-α- D -glucopyranosyloxy-2-(octadeca-9Z,12Z,15Z-trienoyloxy)propanyl octadeca-9Z,12Z,15Z-trienoate, and mixtures thereof from a plant material, said method consisting of the following steps, taken in sequence, of: obtaining a plant material which contains at least one glycoside of a mono- or diacylglycerol selected from the group consisting of 3 β- (i) optionally milling the plant material, (ii) extracting the optionally milled plant material with water and producing a first liquid phase and a first solid phase which contains the at least one glycoside of a mono- or diacylglycerol; (iii) separating the first liquid phase from the first solid phase, wherein the separated first liquid phase comprises a liquid product containing a glycoside of mono- or diacylglycerol, (iv) extracting the first solid phase obtained from step (iii) with water and producing a second liquid phase and a second solid phase which contains the at least one glycoside of a mono- or diacylglycerol, and, (v) separating the second liquid phase from the second solid phase to obtain in the second solid phase a solid concentrate product containing a concentrate of the at least one glycoside of a mono- or diacylglycerol selected from the group consisting of 3 β- wherein no organic solvents are used in any of steps i-v.
