Patent ID: 8431176

Claim:
A repeatable method of retarding oxidation of an oxidizable, organic material comprising flaxseed oil, comprising: adding an effective amount of an antioxidant to said oxidizable, organic material wherein the antioxidant comprises at least one separated fraction, the at least one separated fraction being obtained by a fractionation of a polyepicatechin complex from an enzymatic polymerization by the process comprising: preparing a reaction mixture from enzymatic polymerization of a conjugated flavonoid consisting of a synthetic polyepicatichen; introducing said reaction mixture into an HPLC column at a temperature that is in a range from about 35° C. to about 60° C. and wherein the HPLC column comprises a phenyl column; introducing a mobile phase into said column, said mobile phase comprising an organic solvent/water mixture wherein the organic solvent consists of acetonitrile in a concentration gradient as a function of time; increasing the organic solvent concentration of the mobile phase as a function of time via a non-linear gradient; recovering seven subgroups from the synthesized polymers wherein each of the seven subgroups has a separate eluting fraction and each is spaced in time; and selecting one of the eluting fractions to combine with the oxidizable, organic material.
