A method for the preparation and purification of conjugated linolenic acids is described. The method comprises blending a mixture of vegetable oils and or fats including various concentrations of alpha or gamma and or both linolenic acids with a base. The method transforms approximately over two thirds of .alpha.-linolenic acid (9Z,12Z,15Z-octadecatrienoic acid) into 9Z,11E,15Zoctadecatrienoic acid and 9Z,13E,15Z-octadecatrienoic acid. The method also transforms gamma-linolenic acid (6Z,9Z,12Z-octadecatrienoic acid) into 6Z,8E,15Z-octadeccatrienoic acid and 6Z,10E,12Z-octadecatrienoic acid. In all cases, geometrical isomers and fully conjugated isomers are also produced.

Why it's free to use
- Filed August 6, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 6, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 6, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
