Summary Several oil sources of gamma‐linolenic acid (GLA) were extracted from their corresponding seeds using several extracting systems: A, supercritical fluid extraction (CO 2 ‐SFE); B, methanol/acetyl chloride/hexane (1:0.05:0.5, v/v/v); C, chloroform/methanol/water (1:2:0.8, v/v); D, hexane/diethyl ether (1:1.5, v/v); E, hexane/ethanol (96%) (1:0.9, v/v); F, hexane/ethanol (96%) (1:2.5, v/v); G, 1‐butanol; H, ethanol (96%); I, ethanol (96%)/water (1:1, v/v); J, potassium hydroxide/ethanol (96%) (0.0223:1, p/v). It is noticeable that the total fatty acids extracted by the solvent system I was significantly lower than the amounts obtained by the other extracting systems ( P < 0.05), while the highest GLA purity for the majority of the seeds was obtained by using the system J.
