Punicic acid is a polyunsaturated fatty acid . Its name is derived from the pomegranate ( Punica granatum ), as it was first isolated from pomegranate seed oil in 1935 . But it can also be found in a few other vegetable oils. She is an isomer of α- and γ-linolenic acid , and stereoisomer of α - and β - eleostearic and others.

Punicic acid is a conjugated linolenic acid , abbreviated to CLNA (conjugated linolenic acid). So it contains three conjugated double bonds . Chemically, it is similar to conjugated linoleic acid (CLA), but they only have two conjugated double bonds. In the lipid notation, punicic acid is designated with the abbreviation “18: 3 (ω-5)”, so it belongs to the omega-5 fatty acids .

Punicic acid makes up more than 2/3 of the fatty acids in pomegranate seed oil.
