Chemical compound

Tellimagrandin II is the first of the ellagitannins formed from pentagalloyl glucose. It can be found in Geum japonicum and Syzygium aromaticum (clove). The compound shows anti-herpesvirus properties.

It is laccase-catalyzed dimerized to cornusiin E in Tellima grandiflora. Casuarictin can be formed from it via oxidative dehydrogenation of 2 other galloyl groups in Casuarina and Stachyurus species.
