|Section2= }} 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).〔Purification and Characterization of Eugeniin as an Anti-herpesvirus Compound from Geum japonicum and Syzygium aromaticum. Masahiko Kurokawa, Toyoharu Hozumi, Purusotam Basnet, Michio Nakano, Shigetoshi Kadota, Tuneo Namba, Takashi Kawana and Kimiyasu Shiraki, JPET, February 1, 1998 vol. 284 no. 2, pages 728-735 ((article ))〕 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.〔 == Metabolism == It is formed by oxidation of pentagalloyl glucose in ''Tellima grandiflora'' by the enzyme pentagalloylglucose: O(2) oxidoreductase, a laccase-type phenol oxidase.〔Oxidation of pentagalloylglucose to the ellagitannin, tellimagrandin II, by a phenol oxidase from Tellima grandiflora leaves. Niemetz R and Gross GG, Phytochemistry, February 2003, volume 62, issue 3, pages 301-306, 〕 It is further oxidized to casuarictin, a molecule formed via oxidative dehydrogenation of 2 other galloyl groups in ''Casuarina'' and ''Stachyurus'' species.〔Tannins of Casuarina and Stachyurus species.
