General description

Punicalagin is one of the main ellagitannins (ETs) or hydrolyzable tannins present in pomegranate. The chemical structure of punicalagin consists of gallagic acid and ellagic acid connected through a glucose molecule. It has two (α and β) isomeric forms that can be found in the pomegranate.

Application

Punicalagin has been used in the inhibition assay to check its anti-fungal effects on two C. albicans strains. It has also been used as a polyphenolic compound to probe pyroptosis in macrophages and monocytes.

Biochem/physiol Actions

Punicalagin exhibits an antioxidant effect. Ellagitannins like punicalagin cannot be absorbed directly in humans. First, it converts to ellagic acid, which is further converted to bioavailable urolithin A derivative by human colonic microflora. It elicits an inhibitory effect on nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling pathway which in turn protects against cancer, neuroinflammation, oxidative stress and memory impairment. It has antimicrobial and antibiofilm activities against S. aureus.
Potent immune suppressant isolated from pomegranate.
