FIELD: food industry.

SUBSTANCE: composition is concentrated in terms of compound ethers of pinosylvine and produced by way of crude tall oil distillation or evaporation; the compound ethers acidic residue is formed by linoleic, linolenic, oleic acid or tricyclic, aliphatic or aromatic carboxylic acid. Stilbenes are extracted from the crude tall oil distillation or evaporation fraction containing stilbenes compound ethers; the fraction is concentrated. Then the stilbenes compound ethers are modified into the desired stilbenes by way of stilbenes compound ethers separation from their compound ether group. The crude tall oil distillation or evaporation fractions contain pinosylvine or its compound ethers in an amount of 5 - 95 % of the total weight of the composition.

EFFECT: invention relates to fat-and-oil industry, in particular, to a composition suitable for stilbenes production, to its production method, to a method for extraction of stilbenes from crude tall oil, to a compound ether of resin acid and pinosylvine or to its simple monomethyl ether.
