Tellimagrandin II is the first of the ellagitannins formed from 1,2,3,4,6-pentagalloyl-glucose. It can be found in Geum japonicum and Syzygium aromaticum (clove).^[1]

Tellimagrandin II is an isomer of punicafolin or nupharin A, but the hexahydroxydiphenoyl group is not attached to the same hydroxyl groups in the glucose molecule.

The compound shows anti-herpesvirus properties.^[1]

Metabolism

It is further oxidized to casuarictin, a molecule formed via oxidative dehydrogenation of 2 other galloyl groups in Casuarina and Stachyurus species.^[3]

It has an extremely weak basic(essentially neutral) compound. The compound shows anti-herpesvirus properties.
