Corilagin

Corilagin is an ellagitannin. Corilagin was first isolated in 1951 from Dividivi extract and from Caesalpinia coriaria,[1][2] hence the name of the molecule. It can also be found in Alchornea glandulosa and in the leaves of Punica granatum (pomegranate).[3]

It is a weak carbonic anhydrase inhibitor.[4]

Ellagic acid and corilagin inhibit TGF-β1–dependent EMT and has been shown to attenuate fibrogenesis in a mouse model.[5] Fibrosis is also indicated in many health conditions, including skin aging and MRSA susceptibility.[6]
