For the Contracting States : BE, CH, DE, GB, IT, LI, LU, NL, SE 1. Triglycérides with the general formula (I) : see diagramm : EP0120169,P9,F1 in which R représents the acyl fragment of a polyunsatured fatty acid containing from 18 to 22 carbon atoms, the said acyl fragment being able to be oxidized, R, however, not being able to represent the acyl fragment of eicosatetrayn - 5, 8, 11, 14 - oic, and in which n represents a whole number which can vary from 2 to 16. For the Contracting State : AT 1. Preparation process for triglycerides with the general formula I : see diagramm : EP0120169,P10,F1 in which R représents the acyl fragment of a polyunsatured fatty acid containing from 18 to 22 carbon atoms, the said acyl fragment being able to be oxidized, R, however, not being able to represent the acyl fragment of eicosatetrayn - 5, 8, 11, 14 - oic, and in which n represents a whole number which can vary from 2 to 16, characterized in that dihydroxy acetone is esterified with two molar equivalents of a functional derivative of an acid with the formula II : see diagramm : EP0120169,P11,F2 in which n is defined as previously, a product with the formula III : see diagramm : EP0120169,P11,F3 is obtained, which is treated by a reducing agent not causing saponification of the ester groups, a product with the formula IV : see diagramm : EP0120169,P11,F4 is obtained which is esterified with a functional derivative of a polyunsatured fatty acid, the acid acid having as its formula ROH, R having the same significance as that indicated previously ; in order to obtain a triglyceride with the formula I, which is oxidized, if the case arises, in the case where R is an oxidized acyl fragment, by the action of lipoxygenases or by simple oxidation, in order to obtain the product with the formula I in which R is an oxidized acyl fragment. |
