Punicic acid (PA) is a polyunsaturated fatty acid (18:3 n-5), which is classified as a conjugated linolenic acid. PA is also referred to as a “super CLnA” whose effect is even more potent than that of an ordinary CLnA. It is found mainly in the seeds of the pomegranate fruit (Punica granatum) and Trichoxanthes kirilowii and some other minor sources. It possesses a wide array of biological properties including antidiabetic, antiobesity, antiproliferative, and anticarcinogenic activity against various forms of cancer. In spite of this, the PA has not been explored as a nutraceutical or as an ingredient of food products which can be aimed at specific consumer target groups.

These flavonoid-rich pomegranate phenolic divisions are obligated for anticancer action. Pomegranate peel gives more significant returns of phenolics, flavonoids, and proanthocyanidins than the mash. Flavonoid content was fundamentally more noteworthy inside the strip than the pulp (59 versus 17mg/g), as were proanthocyanidins (11 versus 5mg/g).
