| Common Name | Casuarinin |

| Description | Casuarinin belongs to the class of organic compounds known as hydrolyzable tannins. These are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) that are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units. In model 2, contains at least two galloyl units C-C coupled to each other, and do not contain a glycosidically linked catechin unit. Casuarinin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, casuarinin has been detected, but not quantified in, guava. This could make casuarinin a potential biomarker for the consumption of these foods. After conversion of casuarictin to pedunculagin, the pyranose ring of the glucose opens and the family of compounds including casuariin, casuarinin, castalagin, and castlin, vescalagin and vescalin forms. In some plants including oak and chestnut, the ellagitannins are formed from 1,2,3,4,6-pentagalloyl-glucose and further elaborated via oxidative dehydrogenation (tellimagrandin II and casuarictin formations). It is also found in Casuarina and Stachyurus species and in Alnus sieboldiana. It is a highly active carbonic anhydrase inhibitor. Casuarinin is an ellagitannin. Casuarinin is found in Casuarina sticta, Casuarina stricta, Corylus heterophylla , Cowania mexicana , Eucalyptus viminalis , Kunzea ambigua, Liquidambar formosana , Osbeckia chinensis , Stachyurus praecox, Terminalia chebula and Tibouchina multiflora. Casuarinin was first documented in 2005 (PMID: 15770544). It is an isomer of casuarictin (PMID: 21621513). |
