Retrieval of specific spectroscopic data from scientific publications remains a challenge, even in the internet age. To address this difficulty, spectroscopic databases have been generated to aid researchers in rapidly retrieving of required information. This presentation will describe the generation and use of a searchable database containing solution-state nuclear magnetic resonance spectroscopy (NMR) data for flavan-3-ol monomers and condensed tannin (CT) dimers, trimers and tetramers obtained from the literature to 2015. This compilation of data contains and is searchable by structure, molecular formula, degrees of polymerization of the CT, <sup>1</sup>H and <sup>13</sup>C chemical shifts, and Reaxys database search number. Citations for all literature references used in this database are also provided. We envision that this database will be valuable resource for scientists working in the field of condensed tannin research. The database will be periodically updated so that new NMR data information will be incorporated as it becomes available, typically on a yearly basis. The database is available, free of charge, for use from the US Dairy Forage Research Center (DFRC) website.
